TALAWRENCE DONYEA TENNELL, Appellant

V.

THE STATE OF TEXAS, Appellee

On Appeal from the 85th District Court

Brazos County, Texas

Trial Court Case No. 15-01993-CRF-85

MEMORANDUM OPINION

A jury found appellant Talawrence Donyea Tennell guilty of capital murder

in the death of a seven-month-old baby girl. See TEX. PENAL CODE § 19.03(a)(8).

The court sentenced him to life in prison, without the possibility of parole. See id.

§§ 19.03(b), 12.31(a)(2). Tennell filed a motion for new trial alleging that the State 

failed to disclose exculpatory evidence before trial and that the same evidence

entitled him to a new trial. After a hearing, the trial court denied the motion.

On appeal, Tennell re-urges the grounds for his motion for new trial. He also 

contends that the trial court erred by admitting evidence over his hearsay objection 

and by denying his request for an instruction on the lesser-included offense of 

manslaughter. 

We conclude that Tennell waived his hearsay objection, and he has failed to 

show that he was entitled to a jury instruction on manslaughter. He also has failed 

to prove that the State withheld evidence or that his failure to discover the evidence 

at issue was not caused by his own lack of diligence. To the extent he has 

 

 Pursuant to its docket equalization authority, the Supreme Court of Texas 

transferred this appeal from the Court of Appeals for the Tenth District of 

Texas to this Court. See Misc. Docket No. 17–9066, Transfer of Cases from 

Courts of Appeals (Tex. June 20, 2017); see also TEX. GOV’T CODE § 73.001 

(authorizing transfer of cases). We are unaware of any conflict between 

precedent of that court and that of this court on any relevant issue. See TEX.

attempted to raise constitutional arguments on appeal, they have been waived. 

Accordingly, we affirm the trial court’s judgment. 

Background

Appellant Talawrence Donyea Tennell lived with his girlfriend Crystal 

Harris. Two children lived with them, Harris’s seven-month-old daughter, Hailey, 

and her five-year-old daughter, Riley. 

One afternoon, Harris left Hailey at home, and she asked Tennell to watch 

the baby. When Harris returned home approximately two hours later, Tennell was 

holding Hailey. The baby was unresponsive, and her forehead was bruised. Harris 

started CPR and called 911. An ambulance responded, and Hailey was transported 

to the hospital where she was later pronounced dead. Her cause of death was 

determined to be blunt-force injuries. 

That same evening, detectives of the Bryan Police Department interviewed 

Tennell. He told the detectives that the previous evening, a plastic mouthwash 

bottle containing liquid PCP (phencyclidine) burst in his pants pocket. He claimed 

that the drug contacted his skin, and he started to “trip” from it. Tennell stated that 

Hailey was sleeping when Harris left, and subsequently he also fell asleep.

According to his statement, when he woke, Hailey was on the floor, and she was 

unresponsive. 
4

Tennell was arrested and charged with Hailey’s murder. He was taken to the 

hospital, had blood drawn for a drug test, and was later booked at the Brazos 

County Jail. He was indicted on counts of capital murder, felony murder, and 

injury to a child. He pleaded not guilty, and the case proceeded to trial. Tennell’s 

defensive theory was that he was extremely intoxicated when he killed Hailey, due 

to transdermal absorption of a large dose of PCP that had leaked through his jeans. 

Harris testified that Tennell’s behavior was normal when he returned home

on the evening before Hailey’s death. When Harris left the next day, Hailey was in 

the adults’ bedroom. Upon her return approximately two hours later, Tennell was

in the bedroom, holding Hailey. There was blood on his shirt, and Hailey was 

unresponsive. Harris repeatedly asked Tennell what happened, but he did not 

respond. She stated that he “didn’t look normal.”

During cross-examination, defense counsel asked Harris whether she had 

ever seen or smelled PCP in her apartment while Tennell was there, whether she 

smelled PCP on his pants the night before Hailey’s death, and whether she was 

aware that he sold drugs. Harris stated that she was familiar with the smell of PCP 

from a prior relationship, but she had never smelled or seen PCP in her apartment 

while Tennell was there, including the night before and the day of Hailey’s death. 

Officer R. Snell was one of the first officers to arrive at Harris’s apartment. 

He testified that he spoke with Tennell, who claimed that Hailey had fallen off the 
5

bed while sleeping. Tennell had difficulty answering questions, and Snell believed 

he was under the influence of “some type of substance.” Snell smelled PCP at the 

residence, and he recovered a travel-sized mouthwash bottle from the bottom of the 

steps outside of the apartment. The bottle contained tobacco leaves, which Snell 

testified was consistent with a common method of smoking PCP. The bottle tested 

positive for PCP. 

The emergency room physician who treated Hailey and the assistant medical 

examiner who performed the autopsy each testified. Hailey had sustained various 

fractures to her body and numerous fractures to her skull. Both witnesses believed 

that Hailey’s injuries were not consistent with an accidental fall, but instead had 

been inflicted intentionally by a person.

A crime-scene investigator testified that she collected a pair of folded blue 

jeans from behind the front door of the apartment. The jeans were admitted into 

evidence. A swatch cut from the jeans tested positive for PCP. 

A trained paramedic working in the medical jail division of the Brazos 

County Sheriff’s office, testified that her job was to assess the mental and physical 

status of inmates upon their arrival at the jail. Medical intake was done for every 

booked inmate and included the completion of an “Initial Inmate Medical 

Interview” form. The form had spaces for the inmate’s identifying information, and 

it included questions about medical history, allergies, prescribed medicine, and 
6

history of drug and alcohol use and treatment. The paramedic testified that the 

purpose of the interview was to ascertain the inmate’s medical issues and to better 

treat the inmate in case “something happened in the jail.” 

The paramedic completed Tennell’s medical interview form when he arrived 

at the Brazos County Jail on the evening of Hailey’s death. Tennell admitted that 

he used PCP. The paramedic testified that when inmates admitted to drug use, she 

asked follow-up questions to determine whether an inmate would “detox,” and 

whether there might be behavioral issues due to the drug use. When the paramedic 

asked follow-up questions about Tennell’s drug usage, he said that he had been 

smoking PCP since the beginning of the year, he smoked “a lot” each day, and he 

had last smoked PCP that same day. He further stated: “[I] probably have a lot of 

PCP in my system.” The paramedic recorded Tennell’s responses on the medical 

interview form, which was admitted into evidence over a hearsay objection. Blood 

samples drawn from Tennell hours after Hailey’s death were positive for the 

presence of PCP.

The defense presented testimony from Dr. Mansoor Khan, an expert in 

pharmaceutical science with a specialization in drug delivery systems. He testified 

that based on his review of literature discussing the molecular structure of PCP and 

his knowledge of transdermal absorption, there is a “very high possibility” that the 

substance could permeate through the skin. He further explained that side effects of 
7

high dosages of PCP could include disassociation, agitation, violence, coma, 

memory loss, and death. 

The lead investigator in the case, Detective S. Davis of the Bryan Police 

Department, was not called to testify. Thus the jury never heard about Tennell’s 

statement to Davis that he had spilled PCP on his pants the night before Hailey’s 

death. During trial, Tennell put on the jeans that had been offered into evidence to 

demonstrate to the jury that they were his. 

At the close of evidence, the trial court presented the parties a proposed jury 

charge which included instructions on capital murder and the lesser-included 

offense of felony murder based on the underlying offense of reckless injury to a 

child. Tennell asked the court to also include instructions on the lesser-included

offenses of manslaughter, criminally negligent homicide, and felony murder based 

on the underlying offense of possession of a controlled substance. The court denied 

the requests. The trial court also denied Tennell’s request for an instruction on 

involuntary intoxication. 

During closing arguments, the State argued that Tennell “wanted [Hailey]

dead,” and he had intentionally killed her. Tennell’s counsel argued that the State 

had not proved its case beyond a reasonable doubt. Defense counsel also argued 

that PCP had been absorbed into his skin through the jeans, which were in 

evidence. The State objected to the argument, arguing that there had been no 
8

evidence of transdermal absorption through the jeans, or that Tennell had worn 

them on the day of the murder. The court overruled the objection. 

Defense counsel argued that because Tennell was a “PCP addict,” he knew 

how PCP affected him. But “something different happened the day Hailey died”;

Tennell took a larger dose of PCP than he had ever had before, and that dose 

“could have” come from the PCP on the jeans. Defense counsel showed the jeans

to the jury and argued that when they were collected, the jeans “had a huge wet 

stain” from the PCP. Counsel argued that the smell of PCP was still present on the 

jeans at the time of trial and that she found it “impossible to believe” that Harris 

had no idea that Tennell used and dealt drugs. Counsel asked, “How is it that other 

witnesses who are walking into that house for the very first time immediately smell 

PCP . . . and she couldn’t?” Counsel argued that rather than Tennell being “totally 

normal” when Harris left the apartment, it made more sense that “he was already 

stoned out of his gourd.”

The jury found Tennell guilty of capital murder, and it found that he had 

used a deadly weapon to commit the crime. He was sentenced to life in prison. 

Tennell filed a motion for new trial, alleging that the State withheld evidence that 

Harris saw him wearing the PCP-stained jeans before she left the apartment. After 

a hearing, the trial court denied the motion for new trial. Tennell appeals.

Analysis

Tennell raises two issues relating to events during the trial—the admission 

of hearsay evidence and the denial of a jury instruction about a lesser-included 

offense. We address these issues first. We then consider issues relating to Tennell’s 

motion for new trial and the allegation that the prosecution withheld evidence.

Finally we address the waiver of two issues attempting to challenge the conviction

with constitutional arguments made for the first time on appeal.

I. Medical intake interview form as hearsay

Tennell argues that the trial court erred by admitting, over his objections, a 

page from his medical interview form completed upon his admittance to the Brazos 

County Jail. Trial courts have broad discretion to determine the admissibility of 

evidence, and we will find error only upon a showing of a clear abuse of discretion. 

Montgomery v. State, 810 S.W.2d 372, 378–79 (Tex. Crim. App. 1990); Roberts v. 

State, 29 S.W.3d 596, 600 (Tex. App.—Houston [1st Dist.] 2000, pet. ref’d). As 

long as the trial court’s ruling was within the “zone of reasonable disagreement,” 

there is no abuse of discretion. Montgomery, 810 S.W.2d at 391. 

The State offered into evidence a page from the medical intake questionnaire 

completed by a trained paramedic working for the Brazos County Sheriff’s Office. 

Tennell objected to the exhibit as hearsay. The State argued that the document fell 

under the hearsay exception for statements made for the purpose of medical 
10

diagnosis. See TEX. R. EVID. 803(4). Tennell argued that the document was 

prepared by law enforcement and therefore did not fall under the hearsay 

exception. The State responded that the questionnaire was a “recording” of 

Tennell’s statement, “just like a transcript would be.” The trial court overruled the 

hearsay objection. 

On appeal, the State argues that the questionnaire was admissible as a record 

of regularly conducted business activity. See TEX. R. EVID. 803(6). It further 

contends, as it did at trial, that the exhibit was properly admitted as a statement 

made for medical treatment or diagnosis under Rule 803(4). 

Tennell argues that the paramedic did not testify as a records custodian for 

the Brazos County Jail and the State failed to lay the proper predicate for the 

business-records hearsay exception. However, the rule provides that the predicate 

may be established by the custodian of records for the business or “another 

qualified witness.” TEX. R. EVID. 803(6)(D); see also Melendez v. State, 194 

S.W.3d 641, 644 (Tex. App.—Houston [14th Dist.] 2006, pet. ref’d). Tennell fails 

to provide any argument that the paramedic, despite not being described as a 

records custodian, was not a qualified witness to sponsor the evidence. The 

paramedic specifically testified that she completed the medical interview form 

based on knowledge that she acquired at the time it was imparted to her by 

Tennell. See TEX. R. EVID. 803(6)(A). She further testified that it was a record that 
11

she created “regularly” as part of “the regular course of business at the jail.” See 

TEX. R. EVID. 803(6)(B), (C). We conclude that the trial court would not have 

abused its discretion to admit the document pursuant to the business-record

exception to the hearsay rule. See TEX. R. EVID. 803(6); see, e.g., Moyer v. State, 

948 S.W.2d 525, 528 (Tex. App.—Fort Worth 1997, pet. ref’d).

When a document is admissible as a business record under Rule 803(6), 

statements contained within it nevertheless may be inadmissible hearsay. Garcia v. 

State, 126 S.W.3d 921, 926 (Tex. Crim. App. 2004). If the record contains 

information from a person outside of the business who had no duty to report or to 

report accurately, such information is not admissible unless there is an independent 

qualification for its admission under a hearsay exception. Id. at 926–27. That a 

statement was made for medical diagnosis or treatment can qualify as an 

independent basis for a statement’s admissibility under an exception to the hearsay 

rules. Id.; see TEX. R. EVID. 803(4). A statement made for and reasonably pertinent 

to a medical diagnosis or treatment, and which “describes medical history; past or

present symptoms or sensations; their inception; or their general cause” may be 

admissible as an exception to the rule against hearsay. TEX. R. EVID. 803(4). 

Tennell argues that he was not at the jail seeking treatment for a medical 

condition, and his statements therefore do not fall under the hearsay exception for 

medical diagnosis or treatment. “Rule 803(4) is premised on the declarant’s desire 
12

to receive an appropriate medical diagnosis or treatment, and the assumption that 

the declarant appreciates that the effectiveness of the diagnosis or treatment may 

depend on the accuracy of the information provided.” Munoz v. State, 288 S.W.3d 

55, 58 (Tex. App.—Houston [1st Dist.] 2009, no pet.). A two-part test is used to 

determine whether the declarant believed that his statements would be utilized for 

the purpose of his medical diagnosis or treatment and that the truthfulness of his 

statements can therefore be relied upon. Id.; see Taylor v. State, 268 S.W.3d 571, 

588–89, 591 (Tex. Crim. App. 2008). “First, the statement must be made for the 

purpose of diagnosis or treatment, and the declarant must know that it is made for 

the purpose of diagnosis and treatment.” Munoz, 288 S.W.3d at 58 (citing Taylor, 

268 S.W.3d at 588–89). Second, the statement must be relevant to a medical 

diagnosis or treatment. Id. (citing Taylor, 268 S.W.3d at 591). If the record 

circumstantially supports an inference that the declarant understood the purpose of 

his statement to be for medical treatment or diagnosis, and the need to be truthful 

in his statement, it may be excepted from the rule against hearsay under Rule 

803(4). See Taylor, 268 S.W.3d at 585; see also Munoz, 288 S.W.3d at 58. 

Tennell relies upon Garcia v. State, 126 S.W.3d 921 (Tex. Crim. App. 

2004), to support his contention that his statements were not made for the purpose 

of medical treatment or diagnosis. In Garcia, the Court of Criminal Appeals held 

that Rule 803(4) was inapplicable to statements made by the complainant to an 
13

employee of a women’s shelter because there was no evidence that the 

complainant had visited the shelter for the purpose of receiving a medical 

diagnosis or treatment, or that she actually received medical diagnosis or treatment 

from the shelter’s employees. 126 S.W.3d at 927. 

The facts of this case are distinguishable from Garcia. The trained 

paramedic testified that she worked in the medical division of the jail. She was 

responsible for assessing the mental and physical status of incoming inmates to 

determine whether they had any particular medical needs, and to provide informed 

treatment for inmates during their time at the jail. Unlike the circumstances of the 

complainant’s reports to a shelter employee as described in Garcia, the paramedic 

in this case testified that questions about drug use were used to determine whether 

“the inmate may detox.” As part of the intake process, Tennell’s blood pressure 

and pulse were taken, he was asked about his allergies, medical history, current 

health problems, current physician, and prescribed medications. Although Tennell 

did not go to the jail for the purpose of medical treatment or diagnosis, the trial 

court reasonably could have inferred that the specific purpose of the paramedic’s 

questions was to determine whether Tennell was in need of medical treatment for a 

physical or mental condition, and that the circumstantial evidence demonstrated 

that he answered the questions in cooperation with and in furtherance of that 

purpose. Accordingly, the trial court did not abuse its discretion by admitting the 
14

questionnaire or the statements contained therein. See Munoz, 288 S.W.3d at 58.

We therefore overrule Tennell’s appellate complaint about the admission of 

hearsay evidence. 

II. Lesser-included charge instruction

Tennell was charged with capital murder for intentionally or knowingly 

causing the death of an individual under ten years of age. See TEX. PENAL CODE 

§§ 19.02(b)(1), 19.03(a)(8). The trial court’s proposed jury charge included an 

instruction on capital murder and an instruction on the lesser-included offense of 

felony murder based on the underlying offense of reckless injury to a child. See id. 

§§ 19.02(b)(3), 22.04(a). At the charge conference, Tennell requested additional 

instructions on the lesser offenses of manslaughter, criminally negligent homicide, 

and felony murder based on the underlying offense of possession of a controlled 

substance. The court denied the requests. Despite the option of convicting on the 

lesser-included charge of felony murder, the jury found Tennell guilty of capital 

murder. On appeal, he challenges only the denial of his request for a manslaughter 

instruction. 

Because the manslaughter instruction was requested at trial, if the denial of 

the instruction was an error we will reverse if “some harm” resulted. Nangurai v. 

State, 507 S.W.3d 229, 234 (Tex. App.—Houston [1st Dist.] 2014, pet. ref’d). A

two-part test is applied to determine whether a defendant is entitled to an 
15

instruction on a lesser-included offense. See Cavazos v. State, 382 S.W.3d 377, 

382 (Tex. Crim. App. 2012). The first step is a question of law, which compares

the elements alleged in the indictment with the elements of the lesser offense to 

determine “if the proof necessary to establish the charged offense also includes the 

lesser offense.” Id. The second step of the analysis requires consideration of 

whether there is some evidence that would allow a rational jury to acquit the 

defendant of the greater offense while convicting him of the lesser-included 

offense. Id. at 383; Sweed v. State, 351 S.W.3d 63, 68 (Tex. Crim. App. 2011).

Tennell’s appellate brief acknowledges that a “jury’s failure to find an 

intervening lesser-included offense (one that is between the requested lesser 

offense and the offense charged) may, in appropriate circumstances, render a 

failure to submit the requested lesser offense harmless.” Masterson v. State, 155 

S.W.3d 167, 171 (Tex. Crim. App. 2005). He further concedes that the mental state 

required for manslaughter—recklessness—was the same mental state required for 

the felony-murder charge rejected by the jury in favor of its guilty verdict on the 

capital-murder charge. Still, Tennell suggests that “differences remain” between 

the proposed lesser-included offense of felony murder based on reckless injury to a 

child and manslaughter because the jury would have had to find that he committed 

an act clearly dangerous to human life to convict him of felony murder, see TEX.
16

PENAL CODE § 19.02(b)(3), but that is not an element of manslaughter, see id.

§ 19.04. 

Tennell’s argument does not explain why he was entitled to a manslaughter 

instruction in addition to the lesser-included felony-murder instruction that was 

given. He attempts to analogize his case to Roy v. State, 509 S.W.3d 315 (Tex. 

Crim. App. 2017), a murder case in which the Court of Criminal Appeals held that 

a lesser-included manslaughter instruction was required. Roy is distinguishable 

because some evidence in that case suggested that the appellant deliberately caused 

a fatal car crash, and he was charged with a different theory of murder, TEX. PENAL 

CODE § 19.02(b)(2), which required proof that he intended to cause serious bodily 

injury. Roy, 509 S.W.3d at 317. The Court held that other evidence would have 

allowed a jury to find that the appellant did not intend to cause harm yet did 

disregard the risk of causing death by driving while intoxicated, thus requiring the 

manslaughter instruction. Id. at 319. Unlike this case, Roy did not feature the 

circumstance of a capital-murder charge premised on intentional conduct paired 

with an instruction on a lesser-included felony-murder offense that was premised 

on reckless conduct. 

Tennell fails to suggest what evidence would have allowed a rational jury to 

convict him of only manslaughter while acquitting him of the felony-murder 

charge premised on reckless injury to a child. Cf. Sweed, 351 S.W.3d at 68. “[I]t is 
17

not enough that the jury may disbelieve crucial evidence pertaining to the greater 

offense, but rather there must be some evidence directly germane to the 

lesser-included offense for the finder of fact to consider before an instruction on a 

lesser-included offense is warranted.” Bullock v. State, 509 S.W.3d 921, 925 (Tex. 

Crim. App. 2016). While he suggests that a jury could have chosen to convict him 

of manslaughter because that charge would not have required the jury to find that 

he committed an act clearly dangerous to human life, he fails to suggest what 

evidence would have supported a rational jury in drawing that distinction. See 

Hudson v. State, 449 S.W.3d 495, 498 (Tex. Crim. App. 2014) (holding appellant 

was not entitled to a lesser-included instruction on manslaughter when the proof 

upon which she relied was also sufficient to prove another, greater lesser-included 

offense of capital murder); Flores v. State, 245 S.W.3d 432, 439 (Tex. Crim. App. 

2008) (“A defendant does not satisfy the second prong” of the standard for 

determining if a lesser-included instruction is required “if there is evidence that he 

committed an offense that is a lesser-included of the charged offense but greater 

than the requested lesser-included offense.”). Nor does he explain how he could 

have been harmed by the failure to give the manslaughter instruction when the jury 

convicted him of capital murder despite having the option of convicting him of 

felony murder based on reckless injury to a child. See Masterson, 155 S.W.3d at 
18

171. Accordingly, we overrule Tennell’s challenge to the jury instructions. See

TEX. R. APP. P. 38.1(i).

III. Denial of motion for new trial

Tennell’s remaining issues relate to the denial of his motion for new trial. 

On the morning after he was sentenced, the prosecution informed him that Harris 

stated that when she left Hailey with him, he was wearing the same jeans that had 

been admitted into evidence at trial. Tennell filed a motion for new trial asserting 

that this information was illegally withheld. The motion also argued that this 

information justified a new trial because it constituted newly discovered evidence, 

and that deadlines applicable to a motion for new trial were unconstitutional as 

applied to him.

Prior to trial, Harris had stated that Tennell was wearing jeans on the

morning of the day when Hailey died. The prosecution provided that information 

to defense counsel, in discovery responses, almost two years before trial. The State 

also produced documents indicating that jeans had been collected from the 

apartment and submitted for toxicology testing. Shortly before trial, the jeans were 

tested for the presence of PCP, and the positive results were provided to defense 

counsel. At a hearing on the motion for new trial, the lead prosecutor testified that 

he had not suspected that the jeans in evidence were the same jeans Harris had 

referenced in her pretrial statements indicating that Tennell had been wearing jeans 
19

on the day Hailey died. The prosecution had not shown the jeans or pictures of the 

jeans to Harris prior to trial, and only after sentencing did they learn from Harris 

that she had seen Tennell that day in those particular jeans. 

The State offered into evidence a written report, titled “Supplement: 0033,”

which had been prepared by Detective Davis and which included a brief summary 

of an interview with Harris on the day after Hailey’s death. According to the 

summary, Harris told the detectives that when she left the apartment to take Riley 

to the doctor’s appointment, Tennell was sitting on the living room sofa, wearing 

“a T-shirt, jeans and slides.” Defense counsel agreed that Supplement 33 was 

provided in the State’s first batch of discovery responses, almost two years before 

trial. Defense counsel also agreed that Supplement 33 would have been one of the 

first things reviewed in preparation for the case. 

The State also offered into evidence two recordings of Detective Davis 

interviewing Tennell. The first recording was an interview conducted on the day of 

Hailey’s death, in which Tennell claimed that a bottle of PCP burst in his pocket 

the night before, spilling PCP onto his skin. During the second interview, 

conducted approximately one week later, Detective Davis confronted Tennell with 

inconsistencies between his and Harris’s accounts of certain details about the day 

of Hailey’s death. Detective Davis explained that Harris had said she remembered 

that Tennell was sitting on the couch when she left, and he was wearing a white 
20

t-shirt, jeans, and “red slides.” Defense counsel conceded that recordings of both 

interviews of Tennell were included in the State’s first batch of discovery

responses. Counsel further stated that both audio files had been reviewed “multiple 

times.” Nevertheless, two different lawyers working on Tennell’s defense each 

testified that they had missed both references to “jeans” in the State’s discovery

responses. 

One of the defense lawyers testified that she had asked Tennell if he had 

been wearing the jeans, but he told her he could not remember. That lawyer never 

attempted to speak to Harris before trial, nor did she send an investigator to speak 

with her. The attorney testified that she was worried about damaging Tennell’s 

case if someone from the defense team contacted Harris before trial and said 

something to upset her. 

Noting that the defense asked Harris at trial if she had smelled PCP on 

Tennell’s “pants” the night before Hailey died, the State asked defense counsel 

why she had not also asked Harris about her statement to Detective Davis that 

Tennell had been wearing jeans. Counsel stated that at that time she had not 

remembered the word “jeans” from the report. In an affidavit attached to Tennell’s 

motion for new trial, defense counsel stated that she chose not to ask Harris 

whether she had seen Tennell wearing the PCP-stained jeans because she did not 

know how Harris would answer the question. Counsel believed that if Harris 
21

denied that she had seen Tennell in the jeans, it would destroy the defensive 

theory. Both defense lawyers conceded that Detective Davis would have been 

available as a defense witness, but they made a strategic decision not to call him to 

the stand. 

In support of the argument that the State knew the PCP-stained jeans were 

the same ones Harris had seen him wearing on the day of the murder, Tennell 

offered into evidence a recording and transcript of a call between Harris and a 

defense investigator. During the call, which took place several weeks after trial, 

Harris told the investigator that she had explained to the prosecution prior to trial 

that Tennell’s story about PCP spilling in his pocket the night before Hailey’s 

death could not be true because he was wearing shorts that night, and he did not 

put on “those jeans” until the next morning. 

Harris testified at the hearing on the motion for new trial. She clarified that 

she had told prosecutors and detectives in the case that Tennell was wearing blue 

jeans when she last left him with Hailey, but the prosecution had never shown her 

the jeans or pictures of the jeans that had been collected from the apartment. The 

first time she saw the jeans again after Hailey’s death was when defense counsel 

held them up during closing argument. Harris then realized that they were the jeans 

she had seen Tennell wearing that day, and she informed the prosecutors the 

following day. 
22

Tennell also offered into evidence notes from a meeting Harris had with 

three prosecutors approximately two weeks before trial. Notes from each of the 

three prosecutors indicated that Harris had stated Tennell wore “blue” or “dark

blue” jeans. These notes were not provided to the defense until after trial. 

The motion for new trial was denied. We review a trial court’s ruling on a 

motion for new trial under an abuse-of-discretion standard. Webb v. State, 232 

S.W.3d 109, 112 (Tex. Crim. App. 2007). We view the evidence in the light most 

favorable to the trial court’s ruling, and we must uphold the trial court’s ruling if it 

was within the zone of reasonable disagreement. Id. “[A] trial court abuses its 

discretion in denying a motion for new trial only when no reasonable view of the 

record could support the trial court’s ruling.” Id.

A. Brady violation

Tennell contends that the trial court erred by denying his motion for new 

trial because the State withheld exculpatory evidence. He asserts that the 

prosecution withheld the information that when Harris last left their apartment 

before Hailey’s death, she saw Tennell wearing jeans, and that the jeans were the 

same ones collected from the apartment and that later tested positive for PCP. He 

contends that this information would have supported his theory of transdermal 

absorption of PCP, and therefore would have made the lesser-included offense of 

felony murder based on reckless injury to a child a more viable option for the jury. 
23

“A prosecutor has the affirmative duty to turn over material, favorable 

evidence to the defense.” Little v. State, 991 S.W.2d 864, 866 (Tex. Crim. App. 

1999). The suppression of evidence favorable to a defendant violates his 

due-process rights if the evidence is material either to guilt or punishment, without 

regard to the good or bad faith of the prosecution. Brady v. Maryland, 373 U.S. 83, 

87, 83 S. Ct. 1194, 1196–97 (1963). To establish a Brady violation, a defendant 

must show: (1) the State failed to disclose evidence; (2) the withheld evidence is 

favorable to the defendant; and (3) the evidence is material, that is, there is a 

reasonable probability that had the evidence been disclosed, the outcome in the 

trial court would have been different. Pena v. State, 353 S.W.3d 797, 809 (Tex. 

Crim. App. 2011); Hampton v. State, 86 S.W.3d 603, 612 (Tex. Crim. App. 2002). 

“Favorable evidence is any evidence that, if disclosed and used effectively, may 

make a difference between conviction and acquittal and includes both exculpatory 

and impeachment evidence.” Harm v. State, 183 S.W.3d 403, 408 (Tex. Crim. 

App. 2006). Exculpatory evidence is that which may justify, excuse, or clear the 

defendant from fault, and impeachment evidence is that which disputes, 

disparages, denies, or contradicts other evidence. Id. 

The state’s obligation to reveal Brady material attaches when the 

information comes into the state’s possession. Id. at 407. Brady does not, however, 

require the prosecution to disclose exculpatory or potentially exculpatory evidence
24

that it does not have in its possession and that is not known to exist. Id. Nor is the 

prosecution required “to seek out exculpatory evidence independently on 

appellant’s behalf, or furnish appellant with exculpatory or mitigating evidence 

that is fully accessible to appellant from other sources.” Id. 

It is undisputed that the State provided discovery responses to Tennell’s 

defense counsel almost two years before trial. This information included Detective 

Davis’s report indicating that Harris told him that Tennell was wearing “jeans” 

when she last left him alone with Hailey. It included a recording of Tennell’s first 

interview with police in which he stated that he spilled PCP on his pants the night 

before Hailey’s death. And it included a recording of a second interview of Tennell 

in which Detective Davis told him that Harris claimed he was wearing jeans when 

she left him with Hailey. It is also undisputed the defense was aware prior to trial

that jeans, ultimately admitted into evidence at trial, had been collected from the 

apartment and that a swatch from the jeans tested positive for PCP. 

Tennell disparages the discovery provided to his defense team as a 

“discovery dump.” But he presents no argument or evidence that the State 

deliberately obscured the information that Harris stated he was wearing jeans 

before she left the apartment. The record shows that the State disclosed to 

Tennell’s lawyers the very information that he now complains was illegally 

withheld. To the extent Tennell complains that the State failed to disclose that 
25

Harris saw him wearing the same jeans that tested positive for PCP, he has failed 

to show that the State had that particular information before trial. 

Without a failure to disclose evidence, there is no Brady violation. Harm, 

183 S.W.3d at 406. By providing counsel discovery materials that contained 

references to Harris’s statement and the results of the PCP testing on the jeans, the 

State fulfilled any obligation it had with respect to that evidence. Cf. Gill v. State, 

No. 01-09-01012-CR, 2010 WL 4910210, at *4 (Tex. App.—Houston [1st Dist.] 

Dec. 2, 2010, no pet.) (mem. op., not designated for publication) (citing Harm, 183

S.W.3d at 407) (If the State opens its files for examination by defense counsel, it 

generally fulfills its obligation to disclose exculpatory evidence, unless the 

evidence is not contained in the file.). 

Because Tennell has failed to establish that the State withheld information in 

its possession or that it knew to exist, he has failed to satisfy the first prong

required to show that a Brady violation occurred. Further, the State did not have a 

duty to investigate or develop Tennell’s defense for him. We therefore conclude 

that the trial court did not abuse its discretion by failing to grant a new trial based 

on the alleged Brady violation. 

B. Newly discovered evidence

Tennell separately contends that the trial court erred by denying his motion 

for new trial based on his discovery of material evidence. As with the Brady claim, 
26

this issue is premised on the theory that he did not learn until after trial that Harris 

saw him on the day of Hailey’s death wearing the PCP-stained jeans. 

“A new trial shall be granted an accused where material evidence favorable 

to the accused has been discovered since trial.” TEX. CODE CRIM. PROC.

art. 40.001. To obtain relief under this rule, the defendant must satisfy the 

following four-prong test: (1) the newly discovered evidence was unknown or 

unavailable to the defendant at the time of trial; (2) the defendant’s failure to 

discover or obtain the new evidence was not due to his lack of due diligence; (3) 

the new evidence is admissible and not merely cumulative, corroborative, 

collateral, or impeaching; and (4) the new evidence is probably true and will 

probably bring about a different result in a new trial. State v. Arizmendi, 519 

S.W.3d 143, 149 (Tex. Crim. App. 2017).

Defense counsel claimed they were unaware at the time of trial that Harris 

saw Tennell wearing the PCP-stained jeans the day of Hailey’s death. But even to 

the extent they were subjectively unaware of this information, to be entitled to a 

new trial based on newly discovered evidence, Tennell had to show that the failure 

to discover this evidence was not due to his own lack of diligence. 

Counsel was provided with discovery that included two references to the fact 

that Harris saw Tennell wearing “jeans” the morning of the murder. These

references were contained in the report of the lead detective and in an interview of
27

Tennell himself. The information was provided to defense counsel almost two 

years before trial. 

Even to the extent Tennell’s legal team failed to find or perceive the 

significance of the information disclosed in discovery about Harris’s statement, 

Tennell himself was aware of the facts that he was with Harris on the night before

Hailey’s death and on the following morning. He had personal knowledge of the 

facts at issue, including the circumstance that Harris was a witness who possibly 

could have confirmed the information. Nevertheless, his legal team did not attempt 

to speak with Harris before trial. Tennell’s defense counsel testified at the hearing 

on motion for new trial that this was a strategic decision. 

The trial court reasonably could have determined that through reasonable 

diligence, Tennell could have obtained the information that Harris saw him 

wearing the PCP-stained jeans on the day of Hailey’s death. Accordingly, the court 

did not abuse its discretion by denying a new trial based on the claim of newly 

discovered evidence.

IV. Constitutionality of new-trial motion deadlines

Tennell argues that the deadline for filing a motion for new trial is 

unconstitutional as applied to him because it thwarted his ability to defend his 

constitutional rights.
28

A motion for new trial is a prerequisite to presenting a point of error or issue 

on appeal when it is necessary to adduce facts not in the record. TEX. R. APP.

P. 21.2. Such a motion must be filed within 30 days after the date the trial court 

imposes or suspends sentence in open court. TEX. R. APP. P. 21.4(a). Tennell 

argues that, under his circumstances, the deadline for filing a motion for new trial 

did not allow for “adequate investigation and accompanying support” for 

“extra-record matters.” He broadly argues that because he is indigent and has been 

jailed since his sentencing, and because his trial and appellate counsel were court 

appointed, he is unable to make a substantial claim that he received ineffective 

assistance of counsel. 

While Tennell’s brief outlines potential arguments that he received 

ineffective assistance of counsel, he provides no argument about how the existing 

procedures were inadequate to allow his counsel to raise those issues on the 

schedule established by the rules of procedure, so as to be unconstitutional as

applied to him in this case. See London v. State, 526 S.W.3d 596, 599–600 (Tex. 

App.—Houston [1st Dist.] 2017, pet. ref’d). The brief recites the Fifth, Sixth, and 

Fourteenth Amendments of the U.S. Constitution and Sections 10 and 19 of the 

Texas Bill of Rights as constitutional provisions that are violated by a “systemic 

failure” of rules that are not specifically identified, but the brief makes no legal 

argument about how particular procedural rules violate particular constitutional 
29

protections. See TEX. R. APP. P. 38.1(i) (appellant’s brief must contain “a clear and 

concise argument for the contentions made, with appropriate citations to 

authorities”). Accordingly, we conclude that Tennell has waived his constitutional 

challenge to the procedures governing motions for new trials by failing to support 

the challenge with appropriate legal arguments.

V. Constitutionality of Penal Code Chapter 19 

Finally, Tennell argues that the trial court erred by denying his motion to 

declare Chapter 19 of the Penal Code unconstitutional and failing to set aside the 

indictment on that basis. Chapter 19 codifies the substantive law applicable to 

criminal homicide in Texas.

On appeal Tennell argues that Chapter 19 violates his right to equal 

protection under the federal and state constitutions. In the trial court Tennell made 

an oral motion to the trial court, asking it to declare Penal Code Section 12.31 and 

Code of Criminal Procedure Article 37.071, Section 1 unconstitutional, based on 

the mandatory sentence of life without parole applicable to capital murder 

convictions. However, the record does not reflect that Tennell ever argued that 

Chapter 19 is unconstitutional. 

Because Tennell’s argument on appeal differs from his argument in the trial 

court, he has not preserved this issue for review. See TEX. R. APP. P. 33.1(a); 

Wilson v. State, 71 S.W.3d 346, 349 (Tex. Crim. App. 2002).
