________________________________________________

SCHWARTZMAN, Judge Pro Tem

Chris Allen Stone appeals from his judgment of conviction entered following his 

conditional plea of guilty to second degree murder, Idaho Code §§ 18-4001, 18-4002, 18-

4003(g). Specifically, Stone challenges the district court’s order denying his motion to suppress 

statements he made to police officers. We affirm.

I.

FACTS AND PROCEDURE

Police officers were dispatched to a residence to investigate a shooting. Upon arrival, 

officers made contact with Stone who told the officers that “it was self-defense, she had stabbed 

him and that he had to do it.” Officers then discovered Stone’s estranged wife slumped in the 

back of a van in the driveway with two gunshot wounds in the back of her head. The officers 
2

read Stone his Miranda1 warnings and Stone responded that he understood his rights. Stone then 

volunteered information about himself, including that he was forty-nine years old, he was a 

speech pathologist, he had a concealed weapon permit, he had never been arrested, and he had 

never previously shot anyone or been stabbed.

An ambulance arrived and transported Stone to a hospital for treatment of a stab wound. 

An officer accompanied Stone in the ambulance and stayed with him at the hospital. During the 

ambulance ride, and while at the hospital, Stone continued to volunteer information to the officer

and medical staff. He told the officer that his wife went to his house to pick up some belongings, 

stabbed him with a knife, and then he pulled a gun out of his pocket and shot her twice. Stone 

also said his wife only married him “for a green card.” 

While at the hospital, a detective arrived and, again, read Stone his Miranda warnings. 

Stone reiterated that he understood his rights. The detective also informed Stone that he was not 

under arrest or in custody. Stone then proceeded to tell the detective the same story he told the 

officer. Eventually, Stone received a CT scan, the results of which indicated to the detective that 

Stone was not stabbed by his wife, but instead the stab wound was likely self-inflicted. After 

being confronted with this information, Stone altered his story slightly. He told the detective that 

he and his wife engaged in a verbal altercation and his wife told him that she only married him 

for a green card. Stone told the detective that after hearing those words, he pulled out his gun 

and threatened her. She then allegedly stabbed him and he then shot her twice. Stone was 

placed in custody following his medical treatment. While in jail, Stone called his mother and 

told her the same story he told the detective. 

Stone was charged with second degree murder. He filed a motion to suppress all 

evidence obtained: (1) during the interrogation at his residence; (2) during the interrogation in 

the ambulance; (3) during the interrogation at the hospital; and (4) during his telephone

conversation with his mother while he was in jail. At the suppression hearing, defense counsel 

called two expert witnesses to testify. The first expert, a sociology professor, testified about 

police interrogation techniques and how those techniques were applied during Stone’s 

interrogation. The second expert, Dr. Beaver, a neuropsychologist, testified regarding Stone’s 

psychological makeup and Stone’s medical status during the interrogation. The State objected to 

 

1 Miranda v. Arizona, 384 U.S. 436 (1966).
3

this testimony in its entirety on the grounds of relevance. The district court deferred its ruling on 

the objection until after hearing the testimony. Following testimony, the district court ruled that 

it would consider Dr. Beaver’s testimony regarding Stone’s medical status, but it would not 

consider his testimony regarding Stone’s psychological makeup. 

Following the hearing, the district court denied Stone’s motion to suppress. Stone 

entered a conditional guilty plea to second degree murder, reserving his right to appeal the 

district court’s denial of his motion to suppress. The district court imposed a unified term of 

twenty years, with nine years determinate. Stone appeals.

II.

ANALYSIS

Stone claims that the district court erred when it denied his motion to suppress. 

Specifically, Stone argues that: (1) the district court erred in concluding that Stone’s statements 

were voluntary; and (2) the district court erred by declining to consider the entire testimony of 

Dr. Beaver. The standard of review of a suppression motion is bifurcated. When a decision on a 

motion to suppress is challenged, we accept the trial court’s findings of fact that are supported by 

substantial evidence, but we freely review the application of constitutional principles to the facts 

as found. State v. Atkinson, 128 Idaho 559, 561, 916 P.2d 1284, 1286 (Ct. App. 1996). At a 

suppression hearing, the power to assess the credibility of witnesses, resolve factual conflicts, 

weigh evidence, and draw factual inferences is vested in the trial court. State v. Valdez-Molina, 

127 Idaho 102, 106, 897 P.2d 993, 997 (1995); State v. Schevers, 132 Idaho 786, 789, 979 P.2d 

659, 662 (Ct. App. 1999). 

A. Voluntariness of Statements

Stone claims that police conduct during interrogation became coercive and undermined 

his free will when officers: (1) made implied promises of leniency; (2) used the “false friend” 

interrogation technique; and (3) employed minimization techniques. Stone claims that such 

tactics constitute police coercion and require suppression. Stone also contends that even if this

conduct is not sufficient on its own to merit suppression, the totality of the circumstances 

demonstrate that the officers’ interrogation caused his will to be overborne, resulting in an 

involuntary confession. To support this contention, Stone maintains that: (1) his Miranda

warnings were downplayed; (2) he had no prior experience with law enforcement; (3) he was 

questioned over an eight-hour period; (4) he was in a highly stressful environment; (5) he was in 
4

pain resulting from his stab wound; (6) he had a high blood glucose level; (7) he had been 

administered Dilaudid; (8) he was unable to meet with his parents; and (9) he was highly

suggestible. Based on these factors, Stone contends that the totality of the circumstances show 

that his statements were involuntary and should be suppressed. 

1. Police coercion

In State v. Valero, 153 Idaho 910, 285 P.3d 1014 (Ct. App. 2012), we stated:

The United States Supreme Court has recognized that a noncustodial 

interrogation might in some situations, by virtue of some special circumstance, be 

characterized as one where a defendant’s confession was not given voluntarily. 

See Beckwith v. United States, 425 U.S. 341, 347-48 (1976); see also State v. 

Troy, 124 Idaho 211, 214, 858 P.2d 750, 753 [(1993)]. In order to find a violation 

of a defendant’s due process rights by virtue of an involuntary confession, 

coercive police conduct is necessary. Colorado v. Connelly, 479 U.S. 157, 167 

(1986); State v. Whiteley, 124 Idaho 261, 268, 858 P.2d 800, 807 (Ct. App. 1993). 

The state must show by a preponderance of the evidence that the defendant’s 

statements were voluntary. Whiteley, 124 Idaho at 268, 858 P.2d at 807.

The proper inquiry is to look to the totality of the circumstances and then 

ask whether the defendant’s will was overborne by the police conduct. Arizona v. 

Fulminante, 499 U.S. 279, 287 (1991); Troy, 124 Idaho at 214, 858 P.2d at 753.

In determining the voluntariness of a confession, a court must look to the 

characteristics of the accused and the details of the interrogation, including: 

(1) whether Miranda warnings were given; (2) the youth of the accused; (3) the 

accused’s level of education or low intelligence; (4) the length of the detention; 

(5) the repeated and prolonged nature of the questioning; and (6) deprivation of 

food or sleep. Schneckloth v. Bustamonte, 412 U.S. 218, 226 (1973); Troy, 124 

Idaho at 214, 858 P.2d at 753.

Id. at 911-12, 285 P.3d at 1015-16 (quoting State v. Cordova, 137 Idaho 635, 638, 51 P.3d 449,

452 (Ct. App. 2002)). If the defendant’s free will is undermined by threats or through direct or 

implied promises, then the statement is not voluntary and is inadmissible. Valero, 153 Idaho at 

912, 285 P.3d at 1016; State v. Wilson, 126 Idaho 926, 929, 894 P.2d 159, 162 (Ct. App. 1995).

We start by addressing Stone’s contention that police coercion--using implied promises 

of leniency, the “false friend” interrogation tactic, and minimization techniques--requires 

suppression by itself. First, Stone argues that the detective made implied promises of leniency, 

as demonstrated by the following statements by law enforcement officers: 

The difference between me and a judge, you know, I’ve got the powers to 

investigate. I’ve got the powers to make recommendations and I’ve got the 

powers to keep people safe but, ultimately, he’s the decision maker.

. . . .
5

Who do you think the judge is going to be more lenient, going to be more--going 

to want to work with more, okay?

. . . .

I had every intention of doing--honoring exactly what I told you but once you 

started lying to me about this stuff, you know, all bets are off. I can’t.

. . . .

From my experience, somebody who wants to bullshit the system versus 

somebody who takes accountability, there seems to be some disparity between the 

sentence, okay?

Stone claims that these statements were designed to implicate that confession would lead to 

leniency, and denying guilt would lead to severe punishment. Promises of leniency, especially 

vague assurances of leniency, do not necessarily render a confession involuntary. State v. 

Radford, 134 Idaho 187, 192, 998 P.2d 80, 85 (2000); Wilson, 126 Idaho at 929, 894 P.2d at 162. 

“Rather, they are only a factor to be considered under the totality of the circumstances.” 

Radford, 134 Idaho at 192, 998 P.2d at 85. “The reviewing court must determine whether the 

statements made to the defendant were sufficient to undermine the defendant’s free will.” 

Wilson, 126 Idaho at 929, 894 P.2d at 162. “Promises made by law enforcement officers without 

the authority to fulfill such promises may render a confession involuntary.” Valero, 153 Idaho at

915, 285 P.3d at 1019.

The district court found that any promise of leniency was not sufficiently compelling to 

undermine Stone’s will. We agree. The detective’s statements were vague assurances of 

leniency, if anything. His statements were not connected to a promise of a specific benefit. 

Thus, unlike State v. Kysar, 114 Idaho 457, 459, 757 P.2d 720, 722 (Ct. App. 1988), where the 

officer told the defendant he would be out of jail before his baby was born, the detective never 

promised Stone a specific sentence. The only representation the detective made was that the 

judge could provide a shorter sentence if he cooperated. Further, the detective informed Stone 

that the judge was the ultimate decision maker. See Whiteley, 124 Idaho at 269, 858 P.2d at 808 

(holding that one reason the district court did not err in denying Whiteley’s motion to suppress 

was because the officer informed him that he did not have the authority to fulfill any promise as 

to sentencing). 

Next, Stone contends that the detective and officer used an improper “false friend” 

interrogation tactic that “deprived him of critical information necessary to fairly understand the 

situation and to exercise his free will.” Stone points this Court to State v. Rettenberger, 984 P.2d 
6

1009, 1016-17 (Utah 1999), to explain the “false friend” technique. Using this technique, police 

officers represent to the defendant that they are his friends and that they are acting in his best 

interest. The Utah Supreme Court determined that the false friend technique could become 

coercive if other tactics and factors are present. Id. That Court held that the defendant’s mental 

disabilities and deficiencies, along with the “false friend” interrogation tactic, rendered the 

defendant’s confession involuntary. Id. The eighteen-year-old defendant was found to have 

mental deficiencies because he suffered from A.D.D., had the maturity level of a fifteen-yearold, had a below average I.Q., and was more susceptible to stress and coercion than the average 

person. Id. at 1014. 

In the instant case, Stone maintains that the “false friend” technique combined with his 

mental deficiencies render his statements involuntary. In order to demonstrate that the “false 

friend” tactic was employed, Stone asserts that the detective and officer cast themselves as 

friends and protectors rather than accusers, as demonstrated by the following statements:

STONE: I hope I don’t get in trouble over this. I know I killed 

someone. I hope I don’t get in trouble over this.

UNIDENTIFIED: I’m not a police officer.

[OFFICER]: Again, like he mentioned earlier, our main concern now is 

your well-being internally, you know?

. . . . 

STONE: Will you guys be contacting me? 

[DETECTIVE]: We’re going to cover all this. This is--we’re still--

understand this is--we do--we have to do a very thorough 

investigation just to protect you as much as to protect her, 

right? There’s nobody--

STONE: When you say “her,” do you mean--

[DETECTIVE]: Well, there’s nobody to speak for her so we have to look 

into that, but [by] the same token, we have to protect you 

just as much. Does that make sense in a way?

STONE: I hope so because right now, I feel like I’m all on my own 

and--

[DETECTIVE]: We weren’t there so we have to gather all the facts 

together. [Alright]? And go from there. So that’s what 

we’re trying to do right now.

Stone asserts that this tactic was overbearing because he, like the defendant in 

Rettenberger, suffered from a mental deficiency; namely, that he was highly suggestible, as 

described by Dr. Beaver in the portion of his testimony that was not considered by the district 

court. Stone contends that the “false friend” tactic, combined with his suggestibility, contributed 
7

to a coercive environment that overcame his free will. The district court found that tactics used 

by the police during interrogations did not go “beyond what’s considered appropriate.” 

Additionally, Stone contends that the detective used minimization techniques during the 

interrogation, citing to the following statements:

STONE: I’m going to be a great dad in prison.

[DETECTIVE]: No. This is not the crime of the century. There’s going to 

be consequences but I’ll tell you what, they’re going to be a 

whole hell of a lot more severe if you keep on playing the 

lie and deceit game, okay?

. . . . 

[DETECTIVE]: I’m not saying this is a good thing but it’s not the end of the 

world regardless of what you think in the back of your 

head. But I’ll tell you what, you’re digging yourself in 

deeper by not (inaudible).

. . . . 

[DETECTIVE]: You know, what separates a man from a boy isn’t the 

mistakes they make. It’s the ability to man up and not 

make excuses, make lies, blame everybody else on what 

happened. A bad thing happened, yes. It’s terrible but it’s 

not the end of the world. But you make it and you lie about 

it and you fabricate stuff, yes, you’re going to dig yourself 

in deep. You’re taking a bad situation. You’re making it 

worse.

STONE: What’s worse than murder?

[DETECTIVE]: A liar by far.

Stone argues that these statements demonstrate a minimization technique that contributed 

to the coercive environment. Downplaying the seriousness of the accusation is a factor to 

consider in the totality of the circumstances. Valero, 153 Idaho at 915, 285 P.3d at 1019. A 

finding that the defendant understood the nature of his rights and realized the seriousness of the 

events weighs against a finding of involuntariness. See Wilson, 126 Idaho at 929, 894 P.2d at 

162. The district court found “no evidence that Stone did not understand his rights,” and that he

understood the seriousness of the events. Stone made several comments throughout the 

interrogation indicating that he was aware he could “go to jail for the rest of [his] life.” 

We conclude that the foregoing scenario does not support a finding that Stone’s 

statements were involuntary or that coercive police interrogation techniques were used to 

undermine Stone’s free will. Indeed, the record reflects that Stone’s prior statements were 

substantially the same as his statements following the alleged police coercion. Earlier, Stone 
8

repeatedly stated that he shot his wife after she stabbed him with a knife. When police officers 

first arrived at Stone’s residence, Stone maintained:

And if I hadn’t have had my gun, she’d be calling you right now telling 

you I’m dead.

. . . . 

She stuck that fucking knife deep inside me.

. . . . 

I tell you one thing, if I wouldn’t have had my gun with me, she’d be 

calling you right now telling you I’m dead and she’s alive.

. . . . 

The next thing I know, she’s got her head turned and I got a knife in me 

and a fight (inaudible).

. . . . 

I told you two or three times. I’ll say it again. Right now. If I hadn’t -- I 

have a concealed weapons permit and if I hadn’t have had that fricking concealed 

weapons permit and a gun on me, my wife would be standing here right now 

telling you why I’m dead.

Thereafter, Stone was taken to a hospital where he was treated for his stab wound. While 

receiving medical treatment, Stone was questioned by a detective. Throughout the questioning, 

Stone continued to assert that he shot his wife after she stabbed him:

She turned her head kind of like this and that’s when I saw the knife coming and 

the knife went in me and I immediately grabbed her hand--her hand was on the 

knife and my hand was on her hand and she was trying to push it in me and I was 

trying to take it out. In the meantime, the knife was getting twisted around pretty 

good and it felt like forever and I have a concealed weapons permit.

. . . . 

And I thought of my gun, I took my gun out and I shot her twice.

Again, Stone made these statements prior to any alleged police coercion. Following the results 

of the CT scan, the detective confronted Stone with the theory that Stone shot his wife first and 

then stabbed himself afterwards. However, Stone continued to maintain his original story, 

stating: “She stabbed me and I shot her. That’s the bottom line,” and “All I’m telling you is she 

stabbed me and we played with the knife and I shot her.” Nonetheless, the detective continued to 

question Stone. Eventually, Stone admitted the following:

She said--we said some nasty words while we were walking out but the 

real ones were the (inaudible) “I just married you for a green card,” and she said 

that with her back to me. And I pulled out my gun and I said, “I should just 

fucking kill you you lousy whore.” I remember I said whore or bitch. I think I 

said whore.
9

And she turned around and she had her little knife with her and we got 

into each other’s face and we started saying shit to each other and she poked me 

with the knife and she started--and I lifted my gun up and that’s when I was going 

to shoot her and she turned her back to me and I killed her and that is the end of 

that.

Though Stone added additional facts, such as the specific verbal altercation and the fact 

that he took out his gun before being stabbed, he continued to assert that his wife stabbed him 

before he shot her. Nevertheless, the detective continued to ask if Stone’s wife really stabbed 

him:

[DETECTIVE]: Did she really stick you?

STONE: Yeah, she really stuck me. She really did and I’m not 

going to bullshit you.

. . . . 

[DETECTIVE]: Straight up, Chris, did she stick you?

STONE: Yes, she did stick me.

[DETECTIVE]: I just want to make sure that we’re being completely 

honest.

STONE: Yes, she did stick me. Yes, she did stick me.

Throughout the course of the interrogation, Stone continually maintained that his wife 

stabbed him and never adopted the detective’s version of events that he stabbed himself. Thus, 

the statements made after the alleged police coercion were substantially the same as those made 

prior to the alleged coercion. In both instances, Stone asserted that he shot his wife after she 

stabbed him. Based on the foregoing, we conclude that the conduct of law enforcement officers, 

including their alleged statements of implied promises, their alleged minimization of the crime, 

and their alleged “false friend” interrogation tactic, were not sufficiently coercive to overcome 

the will of Stone and render his statements involuntary. Accordingly, we uphold the district 

court’s conclusion that Stone’s statements were not the product of police coercion elicited 

through the use of improper interrogation techniques.

2. Totality of the circumstances

We next address Stone’s contention that the Bustamonte factors weigh in favor of a 

finding that Stone’s statements were involuntary. As to the first factor discussed in Bustamonte,

Stone contends that his Miranda warnings were downplayed as mere formalities, and therefore 

he never understood the adversarial nature of the police officers’ interrogations. A police officer 
10

provided Stone his Miranda warnings upon arrival at Stone’s residence. Immediately after 

providing Stone with those rights, the following conversation occurred:

[OFFICER]: . . . Do you understand those?

STONE: Yeah.

[OFFICER]: Okay. 

STONE: Is it in my best interests to just be quiet?

[OFFICER]: Completely up to you.

STONE: (Inaudible) what happened.

[OFFICER]: And obviously we like to get two sides of the story, you know 

what I mean? I want you to go ahead and stand up for me real 

quick, okay?

STONE: Okay. I’ll do whatever you want. I’m a professional.

Stone then proceeded to volunteer information about the incident. Stone received 

Miranda warnings a second time at the hospital. He again stated that he understood his rights. 

The district court found “there is no question that the rights were given.” Further, the district 

court found that Stone “understood his rights and chose not to rely on those rights when he 

spoke.” Accordingly, the court found that Stone “waived his rights.” The district court’s 

findings are supported by substantial and competent evidence. A district court’s conclusion that 

a defendant made a knowing and voluntary waiver of his or her Miranda warnings will not be 

disturbed on appeal where it is supported by substantial and competent evidence. State v. 

Custodio, 136 Idaho 197, 201, 30 P.3d 975, 979 (Ct. App. 2001).

As to the youth of the accused and his level of education, the record demonstrates that

Stone was forty-nine years old at the time of the interrogation. He was well-educated and had a 

master’s degree in speech pathology. “Such a person is more resistant to interrogation than a 

person who is very young, uneducated, or weak-minded.” Valero, 153 Idaho at 912, 285 P.3d at

1016 (determining that the characteristics of a thirty-eight-year-old defendant with a high school 

education weighed against finding that the confession was involuntary).

As to the deprivation of food or sleep, the district court found that Stone was not

“deprived of his basic needs during the time that he was hospitalized.” However, while at the 

hospital, Stone was administered Dilaudid, which is an opiate-type medication that relaxes the 

patient. Additionally, Stone’s blood was tested and his blood glucose level was over four times 

the normal level. Stone asserts that this impaired his ability to think clearly. The district court 

did not find “any evidence to substantiate claims that the medication or the high blood sugar was 

affecting [Stone’s] mental acuity.” We agree. Our review of the record indicates that Stone 
11

understood the questions posed to him and delivered clear and articulate responses. Further, 

Stone admitted that he was “cognitive, coherent” even though he was in pain. Additionally, 

Stone was described by the detective as “pleasant, lucid, joking, alert, and outgoing.”

As to the length of the detention, the record demonstrates that officers asked Stone 

questions during a span of six to eight hours. However, during that time span Stone was at a 

hospital receiving medical treatment for a stab wound and undergoing medical examinations, 

such as a CT scan. Therefore, Stone was not consistently or continually questioned during the 

six to eight-hour time span. Further, the district court found that the questioning would not have 

lasted as long as it did if Stone “hadn’t volunteered so much information.” 

We conclude that the factors discussed in Bustamonte weigh against a finding that

Stone’s statements were involuntary. Stone was provided his Miranda warnings on two 

occasions and stated that he understood his rights. He was forty-nine years old at the time and 

well-educated. There is no evidence to support the assertion that the medication he was given,

his blood glucose level, or the pain resulting from his wound diminished his ability to understand 

his situation. On the contrary, the record demonstrates that Stone clearly understood the events 

as they transpired and continually volunteered information to law enforcement officers at his 

residence, during transportation to the hospital, and while at the hospital.

Finally, this case is distinguishable from our recent decision in Valero, where we 

affirmed the district court’s decision to suppress statements on the basis that they were 

involuntary. In that case, Valero initially denied all the allegations. Following a polygraph 

examination, the detective told Valero that polygraph examinations were one-hundred percent 

accurate and were admissible in court. Valero, 153 Idaho at 914, 285 P.3d at 1018. The 

detective further informed Valero that he could be charged with a more serious crime of lying to 

the police if he did not confess. Id. at 916, 285. P.3d at 1020. Thereafter, Valero changed his 

initial statements and confessed to the crimes charged. This Court held that under the totality of 

the circumstances, Valero’s confession was involuntary because the detective threatened him 

with a greater crime of lying to the police and the detective made legal misrepresentations and 

assertions. Id. The instant case is distinguishable in several aspects. First, Stone never 

materially changed his initial account of the events and never admitted to the crime. Second, the 

detective never made any legal misrepresentations and never threatened Stone with a greater 

crime of lying to the police. 
12

Based on the foregoing, we conclude that the district court’s findings are supported by 

substantial evidence from the record. Accordingly, the district court did not err in denying the 

motion to suppress, under the totality of the circumstances, on the basis of the evidence it 

considered. 

B. Testimony of Dr. Beaver

Stone contends that Dr. Beaver’s testimony regarding Stone’s psychological makeup, 

including his suggestibility, was relevant to show that his statements were not made voluntarily. 

The State contends that police coercion must be established before determining whether 

Dr. Beaver’s testimony regarding Stone’s psychological makeup was relevant. The State argues 

that police coercion did not exist; therefore, Stone’s inquiry regarding Dr. Beaver’s testimony is 

not reached. We review questions of relevancy de novo. State v. Raudebaugh, 124 Idaho 758, 

764, 864 P.2d 596, 602 (1993). “[T]he Rules of Evidence generally govern the admission of all 

evidence in the courts of this State.” State v. Meister, 148 Idaho 236, 240, 220 P.3d 1055, 1059 

(2009) (emphasis in original). “All relevant evidence is admissible except as otherwise provided 

by these rules or by other rules applicable in the courts of this state.” Idaho Rule of 

Evidence 402. Evidence is relevant if it has “any tendency 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.” I.R.E. 401. 

In the instant case, the district court found that Dr. Beaver’s testimony regarding Stone’s 

psychological makeup, including his suggestibility, was not relevant to its determination of 

whether Stone’s confession was voluntary. However, the district court did consider Dr. Beaver’s 

testimony regarding the effects of pain medications administered to Stone and the effects of 

Stone’s diabetes. During the suppression hearing, Dr. Beaver testified that Stone was “highly 

suggestible in comparison to the average person,” and tested higher than the average person in 

respect to his suggestibility. As a result, the expert testified that Stone was “more prone to want 

to please people in authority or power.” Additionally, Dr. Beaver testified that Stone was 

socially anxious with few close friends and was very attached to his parents. Stone argues that 

this evidence should be a factor in determining whether police coercion caused his will to be 

overborne and, thus, resulted in involuntary statements. We agree.

The United States Supreme Court has said, “coercion can be mental as well as physical.” 

Fulminante, 499 U.S. at 287 (quoting Blackburn v. Alabama, 361 U.S. 199, 206 (1960)). “[A]s 
13

interrogators have turned to more subtle forms of psychological persuasion, courts have found 

the mental condition of the defendant a more significant factor in the ‘voluntariness’ calculus.” 

Colorado v. Connelly, 479 U.S. 157, 164 (1986). Idaho courts have also looked to the 

defendant’s subjective characteristics in considering the voluntariness of a confession. See

Woodward v. State, 142 Idaho 98, 108, 123 P.3d 1254, 1264 (Ct. App. 2005) (among other 

factors, court looks to facts that defendant was “of normal intelligence,” and had “had prior 

experience with law enforcement officers.”); State v. Cordova, 137 Idaho 635, 639, 51 P.3d 449, 

453 (Ct. App. 2002) (court lists whether defendant had “a history of mental illness” as a 

consideration bearing on the voluntariness of his statements, but notes that only counsel’s 

representation to this effect, as opposed to actual evidence, was presented at the suppression 

hearing); State v. Tapp, 136 Idaho 354, 364, 33 P.3d 828, 838 (Ct. App. 2001) (unusually low 

I.Q. or cognitive defects).

Here, Dr. Beaver testified that Stone was highly suggestible and socially anxious. While 

Stone’s suggestibility and mental condition alone are not sufficient to justify suppression absent 

a showing of police coercion; nonetheless, it is a factor the court should have considered under 

the totality of circumstances. Therefore, we determine that the district court erred by failing to 

consider Dr. Beaver’s testimony concerning the psychological makeup of Stone. 

Next we must determine whether the district court’s failure to consider Dr. Beaver’s 

testimony regarding Stone’s psychological makeup requires remand to the district court or 

whether this Court can address the merits of the issue. The district court made an evidentiary 

ruling when it found that Dr. Beaver’s testimony regarding Stone’s psychological makeup was 

irrelevant. The Idaho Rules of Evidence require that when appealing an exclusion of evidence, 

the “substance of the evidence was made known to the court by offer or was apparent from the 

context . . . .” I.R.E. 103(a)(2). The purpose of this rule is to preserve a record for appeal and to 

enable the court to rule on the evidence’s admissibility. Kuhn v. Coldwell Banker Landmark, 

Inc., 150 Idaho 240, 251, 245 P.3d 992, 1003 (2010). See also State v. Joslin, 145 Idaho 75, 82, 

175 P.3d 764, 771 (2007). In the instant case, the district court elected to hear Dr. Beaver’s 

entire testimony as an offer of proof, as well as received briefing and oral argument regarding the 

issue. Therefore, the record contains a sufficient offer of proof for this Court to determine 

whether the entirety of Dr. Beaver’s testimony would alter the district court’s finding that 
14

Stone’s statements were voluntary. We conclude that remand is unnecessary and elect to address 

the merits of the issue.2

We hold that the district court’s error was harmless. “In Idaho, the harmless error test 

established in [Chapman v. California, 386 U.S. 18 (1967)] is now applied to all objected-toerror.” State v. Perry, 150 Idaho 209, 221, 245 P.3d 961, 973 (2010). See State v. Pearce, 

Docket No. 30502 (Ct. App. May 30, 2007) (unpublished) (holding that the district court’s error 

of excluding an expert’s testimony regarding suggestibility, where an extensive offer of proof 

had been made, was harmless error);

3 cf. State v. Critchfield, 153 Idaho 680, 685, 290 P.3d 1272, 

1277 (Ct. App. 2012) (applying the harmless error analysis where the district court improperly 

excluded expert testimony and finding that the error was not harmless). Accordingly, the State 

has the burden of demonstrating that the error did not contribute to the district court’s decision to 

deny Stone’s motion to suppress. The State asserts that even if the district court were to consider 

Dr. Beaver’s testimony, the totality of the circumstances support the finding that Stone’s 

statements were voluntary. We agree. 

The purpose of Dr. Beaver’s testimony was to demonstrate that Stone’s psychological 

makeup, particularly his high suggestibility, contributed to his will becoming overborne. 

Dr. Beaver testified that suggestibility measures how easily it is to change a person’s opinion, 

recollection, or perception. Dr. Beaver further testified that Stone had a high level of 

suggestibility that caused Dr. Beaver to “have significant concern about how easily . . . his 

memory of events could be changed.”

Even considering Dr. Beaver’s entire testimony, the record reveals that Stone never 

submitted himself to the detective’s version of events. The detective implied that he believed 

Stone shot his wife and then stabbed himself with a knife. Stone never admitted to this version 

 

2 We note that the district judge handling this case has since retired from the bench.

3 State v. Pearce, Docket No. 30502 (Ct. App. May 30, 2007) (unpublished) is an opinion 

that was not published in the permanent law reports. In that opinion, this Court determined that 

the trial court erred by excluding expert testimony, but that the error was harmless. Following 

this Court’s opinion, the Idaho Supreme Court took the case on review. The Idaho Supreme 

Court affirmed the ruling of the district court, but on different grounds. The Idaho Supreme 

Court determined that the trial court’s exclusion of expert testimony was not error; therefore, it 

never discussed the harmless error test. State v. Pearce, 146 Idaho 241, 245-48, 192 P.3d 1065, 

1069-72 (2008).

of events. Instead, Stone continued to assert that his wife stabbed him and then he shot her 

afterwards. As the night progressed, the only change that Stone made in his version of events 

was that he admitted to taking his gun out of his pocket and threatening his wife prior to being 

stabbed. Nonetheless, he still claimed that his wife stabbed him. Even after being presented 

with evidence indicating the stab wound was self-inflicted, Stone continued to maintain that the 

stab wound was created by his wife. As such, Stone’s recollection of the events was never 

substantially altered to submit to the detective’s “suggested” version.

Further, the totality of the circumstances, including considering Dr. Beaver’s testimony in 

its entirety, show that Stone’s statements were voluntary. As discussed above, Stone was aware 

of his Miranda rights, the seriousness of his accusations, and the questions posed to him. His 

responses to questions demonstrate that he was coherent, rational, and knowledgeable. He 

willingly volunteered information to law enforcement officers prior to being questioned and 

continued, unrestrained, to volunteer information throughout the night whether a question was 

posed to him or not.

On the whole, the district court had before it the audio recordings of Stone’s

interrogation, the transcript of the interrogation, expert testimony regarding police interrogation 

tactics, and expert testimony regarding Stone’s mental acuity and physical condition at the time 

he made incriminating statements. Additionally, the district court acknowledged that Stone

“never did truly adopt [the detective’s] position that he had stabbed himself.” Given the fact that 

we have the entire record before us, we conclude the district court’s selective exclusion of 

Dr. Beaver’s “suggestibility” testimony amounts to harmless error and that remand is 

unnecessary because the trial court’s conclusions would have been the same.

III.

CONCLUSION

Stone’s statements to law enforcement authorities were not the product of police coercion 

elicited through the use of overreaching interrogation techniques. In addition, under the totality 

of the circumstances, his statements were voluntary. Therefore, the district court’s order denying

Stone’s motion to suppress is affirmed.
