AFFIRMED

Appellant Aritzaid Santiago was convicted by a jury of injury to a child causing serious 

bodily injury and assessed punishment at five years confinement and a $10,000.00 fine. On 

appeal, Santiago asserts: (1) the trial court erred in admitting testimony over an objection to 

relevancy, and (2) the evidence was factually insufficient to sustain Santiago’s conviction. We 

affirm the judgment of the trial court.

BACKGROUND

On April 11, 2006, Santiago was taking care of N.B, the five month-old victim, while the 

child’s mother was at work. With twin girls of her own only a year older than N.B., Santiago 

had become good friends with N.B.’s mother and cared for N.B. on a regular basis. When N.B.’s 

father arrived for N.B., Santiago explained that N.B. had not slept and had been crying all day. 

After many disturbing warning signs, such as N.B.’s eyes rolling backward, vomiting, and 

eventually becoming pale and listless, N.B.’s parents took him to the hospital. 

Based on a physical examination and medical tests, a pediatric neurosurgeon concluded 

N.B. was suffering from subdural bleeding. The hospital staff then contacted the police amid 

concerns that the injury was intentional. While N.B. was in surgery, N.B’s parents as well as 

Santiago were questioned by police. Santiago admitted to shaking N.B., even demonstrating 

how she shook the infant, because he would not stop crying. After pleading not guilty, a jury 

convicted Santiago of causing serious bodily injury to a child.

RELEVANCY OF TESTIMONY

In her first issue on appeal, Santiago argues the trial court erred in allowing Dr. Mario 

Fierro to testify about N.B.’s continuing physical impairment over an objection to relevancy. 

We review the admissibility of evidence for an abuse of discretion. Weatherred v. State, 15 

S.W.3d 540, 542 (Tex. Crim. App. 2000). An abuse of discretion occurs when a trial court’s 

decision lies outside the zone of reasonable disagreement. Id. Further, no reversible error exists 

in the exclusion or admission of evidence unless a substantial right of a party is affected. TEX. R.

APP. P. 44.2 (b); Rodriguez v. State, 974 S.W.2d 364, 370 (Tex. App.—Amarillo 1998, pet. 

ref’d).

The State argues Dr. Fierro’s testimony was offered to prove serious bodily injury. 

Serious bodily injury means “bodily injury that creates a substantial risk of death or that causes 

death, serious permanent disfigurement, or protracted loss or impairment of the function of any 

bodily member or organ.” TEX. PENAL CODE ANN. § 1.07 (a)(46) (Vernon 2003). “Evidence of 

a victim’s serious bodily injury [may] be admissible at the guilt/innocence phase of the trial.” 

See Wilson v. State, 772 S.W.2d 118, 120 n.4 (Tex. Crim. App. 1989). Rule 401 states evidence 

is relevant only if it tends to make “the existence of any fact that is of consequence to the 

determination of the action more probable or less probable than it would be without the 

evidence.” TEX. R. EVID. 401. 

Dr. Fierro began treating N.B. a few weeks after the surgery and placed N.B. in an early 

childhood intervention program for physical and occupational therapy. Dr. Fierro testified as to 

N.B.’s physical and neurological development. Because the testimony is directly related to the 

issue of protracted loss or impairment, it is relevant to the question of serious bodily injury. See 

Moore v. State, 739 S.W.2d 347, 352 (Tex. Crim. App. 1987) (requiring the prosecution to 

present “probative evidence from which a rational trier of fact could infer beyond a reasonable 

doubt that the bodily injury [was serious bodily injury]”). Because Dr. Fierro’s testimony makes

it more probable that N.B. suffered serious bodily injury than it would have been without the 

evidence, the testimony was relevant. See TEX. R. EVID. 401; Montgomery v. State, 810 S.W.2d 

372, 376 (Tex. Crim. App. 1990) (finding that evidence is relevant when a reasonable person 

finds it helpful in determining the truth or falsity of any consequential fact). Accordingly, the 

trial court did not abuse its discretion by admitting the testimony.

FACTUAL SUFFICIENCY

Santiago also asserts the evidence at trial was factually insufficient for the jury to 

conclude N.B.’s injury was the result of being shaken. When considering a factual sufficiency 

challenge, an appellate court views all of the evidence in a neutral light and only sets aside the 

verdict if the evidence is so weak that the verdict is “clearly wrong and manifestly unjust;” or if 

the verdict is “against the great weight and preponderance of the evidence.” Watson v. State, 204 

S.W.3d 404, 414-15 (Tex. Crim. App. 2006). 

To prove the charged offense, the State had to establish Santiago “intentionally, 

knowingly, recklessly, or with criminal negligence, by act” caused “serious bodily injury” to 

N.B., a child fourteen years or younger. See TEX. PEN. CODE ANN. § 22.04 (a)(1) & (c)(1) 

(Vernon 2003). On appeal, Santiago only challenges the sufficiency of the evidence related to 

the cause of N.B.’s injury. Our analysis must consider the evidence Santiago claims to be most 

important in allegedly undermining the jury’s verdict. Sims v. State, 99 S.W.3d 600, 603 (Tex.

Crim. App. 2003); accord Cain v. State, 958 S.W.2d 404, 408 (Tex. Crim. App. 1997).

Santiago argues the testimony of medical experts from both sides is conflicting and, 

therefore, insufficient to support the conviction. We disagree. When presented with inconsistent 

testimony, it was within the jury’s purview to determine the credibility of the testimony. See 

Fuentes v. State, 991 S.W.2d 267, 271 (Tex. Crim. App. 1999) (noting that inconsistency goes to 

the credibility of the witnesses and the jury is the sole judge of that issue). Especially in cases, 

such as this, with conflicting expert testimony, we are not at liberty to say the jury should have 

believed Santiago’s expert over the State’s expert, when both opinions were based on probative 

evidence. See Barry v. State, 165 Tex. Crim. 204, 305 S.W.2d 580, 585-86 (1957) (“The jury 

was at liberty to believe any part of the [conflicting expert] testimony and reject the 
04-08-00788-CR

- 5 -

remainder.”); see also Alexander v. State, 282 S.W.3d 701, 711 (Tex. App.—Houston [14th 

Dist.] 2009, pet. filed); Maness v. State, No. 04-97-00848-CR, 1998 WL 690998, at *8 (Tex.

App.—San Antonio Oct. 07, 1998, pet. ref’d) (mem. op., not designated for publication).

At trial, the attending physician, a pediatric neurosurgeon, testified that N.B.’s injuries 

were the result of being shaken. She also testified that the injuries occurred up to twelve hours 

before the Computerized Axial Tomography (CT scan) at 6:00 p.m. Santiago argues that since 

multiple people cared for N.B. during those twelve hours, that one or more individuals could 

have caused the injuries. However, the videotaped recording of Santiago answering police 

questions and demonstrating how she shook N.B. earlier that day was also admitted before the 

jury. In Santiago’s defense, Dr. Richard Hirschberg testified that, in his opinion, N.B.’s medical 

record did not show conclusive evidence of an intentional act of shaking.

In the face of conflicting testimony, the jury was free to believe the opinion of the State’s 

experts that N.B.’s symptoms were consistent with shaken baby syndrome. See Barry, 305 

S.W.2d at 585-86. This evidence was factually sufficient to support the jury’s finding that 

N.B.’s injury was the result of being shaken by Santiago. Consequently, we cannot say that the 

evidence is so weak that the verdict is clearly wrong and manifestly unjust, or against the great 

weight and preponderance of the evidence. See Watson, 204 S.W.3d at 414-15.

CONCLUSION

We hold that Dr. Fierro’s testimony was directly related to the issue of serious bodily 

injury and was, thus, relevant and properly admitted by the trial court. Additionally, we hold the 

evidence is factually sufficient to support the conviction. We, therefore, affirm the judgment of 

the trial court.
