[¶ 1] Dean Michaud (“Michaud”) appeals from the judgment of the Superior Court (Aroostook County, Calkins, J.) in a jury-waived trial finding him guilty of reckless manslaughter in violation of 17-A M.R.S.A. § 203(1)(A) (1983 & Supp.1998), 1 and from the sentence imposed. Michaud contends that: (1) the court erred in denying his motion to suppress; (2) the evidence was not sufficient to either (a) establish the corpus delicti for homicide, (b) establish recklessness, (c) establish causation, or (d) disprove his self-defense claim; (3) the court erred in denying his request for specific findings of fact and conclusions of law; and (4) the court erred in sentencing. Finding no error, we affirm both the judgment and the sentence.
[¶ 2] The State presented evidence at trial that would permit the following factual findings: On September 11, 1996, Michaud caused the death of Thomas Mató (“Mató”) by drowning him in the St. John River in Frenchville, Maine. Prior to the incident, Maid had recently begun courting Michaud’s former girlfriend, Barbie Ouellette (“Ouel-lette”). After an “on again, off again” romantic relationship that lasted approximately fourteen months, Michaud broke up with Ouellette for the third and final time on September 3,1996. Mató met Ouellette during the same week and began spending time with her, much to Michaud’s chagrin. Mi-chaud became jealous because Ouellette showed a growing interest in Mató. After many unsuccessful attempts to salvage his relationship with Ouellette, Michaud asked Mató to accompany him to the St. John River to talk on September 11, 1996. An altercation broke out between Michaud and Mató in the shallow water near the rocky shore of the river. During the struggle, Michaud pushed or struck Mató and caused him to fall on his back and hit his head on the rocks. While grappling in the shallow water with Michaud on top of him, Mató inhaled water while his head was below the surface. At the time of the drowning, Michaud was an eighteen-year-old student at the University of Maine at Fort Kent (“UMFK”) and a citizen of New Brunswick, Canada. Maid was a twenty-year-old UMFK student. Michaud was approximately 6’4” tall and weighed around 180 to 200 pounds. Mató was 5’10” tall and weighed 150 pounds. An autopsy examination revealed numerous injuries to Maki’s head, throat, neck, and back. Michaud had no injuries except for one or two small red spots on his face.
I.
[¶ 3] Michaud first asserts that the court erred in denying his motion to suppress statements made to the police on September 11 and 12, 1996, because he was “in custody” and did not receive Miranda
2
warnings. The United States Supreme Court in
Miranda v. Arizona
held that, in order to safeguard an uncounseled criminal defendant’s Fifth Amendment privilege against self-incrimination, law enforcement officers may not begin a custodial interrogation before warning the
*1226
suspect “that he has a right to remain silent, that any statement he does make may be used as evidence against him, and that he has a right to the presence of an attorney, either retained or appointed.”
Miranda v. Arizona,
[If 4] A defendant is “in custody” if subject to either: (a) a formal arrest; or (b) a “restraint on freedom of movement [to] the degree associated with a formal arrest.”
Stansbury v. California,
(1) the locale where the defendant made the statements;
(2) the party who initiated the contact;
(3) the existence or non-existence of probable cause to arrest (to the extent communicated to the defendant);
(4) subjective views, beliefs, or intent that the police manifested to the defendant, to the extent they would affect how a reasonable person in the defendant’s position would perceive his or her freedom to leave;
(5) subjective views or beliefs that the defendant manifested to the police, to the extent the officer’s response would affect how a reasonable person in the defendant’s position would perceive his or her freedom to leave;
(6) the focus of the investigation (as a reasonable person in the defendant’s position would perceive it);
(7) whether the suspect was questioned in familiar surroundings;
(8) the number of law enforcement officers present;
(9) the degree of physical restraint placed upon the suspect; and
(10) the duration and character of the interrogation.
See, e.g., State v. Gardner,
[¶ 5] After examining the above factors in light of the September 11,1996 hospital interview, the court concluded that, “under the totality of the circumstances, ... a reasonable person in the defendant’s position would not have believed he was in police custody and constrained to a degree associated with formal arrest.” After analyzing the facts surrounding the September 12, 1996 interview at the crime scene, the court also found “little merit to the suggestion that the interviews ... were custodial.” Based on the above custodial interrogation factors, the record contains evidence that rationally supports the conclusion that Michaud was not “in custody” when he spoke with the police at the hospital.
See State v. Carr,
*1227 ii.
A.
[¶6] Michaud challenges the trial court’s
corpus
delicti
3
ruling. In a homicide case, the
corpus delicti
rule requires the State to establish both that: (1) the victim died; and (2) a criminal agency was responsible for the death.
4
See State v. Buzzell,
[¶ 7] Under the first prong of the State’s burden of proof, we review the trial court’s factual findings only for clear error.
See Chad B.,
[¶ 8] Pursuant to the
corpus delicti
rule, a court may not allow a defendant’s admission in evidence
5
until the State has met its burden of proving the
corpus delicti
to a “substantial belief’ standard, under the first prong.
6
See State v. Reed,
[¶ 9] When viewed objectively, the facts as the court found them were “sufficient to establish a substantial belief that [Maki] died as the result of a criminal agency,” independent of Michaud’s post-conviction admissions.
Id.
In light of Maki’s injuries and Dr. Ryan’s testimony, the evidence “would warrant a prudent and cautious person to believe” that Maki died as a result of criminal means, rather than by natural causes, accident, or suicide.
Id.
Nor would the existence of other explanations for the circumstances surrounding Maki’s death preclude such a finding.
7
See State v. Reed,
[¶ 10] Under the second prong of the State’s burden of proof, we review the entire record (including the defendant’s confessions or admissions) to see if it discloses sufficient evidence for the factfinder rationally to find beyond a reasonable doubt every element of the
corpus delicti. See Chad B.,
B.
[¶ 11] Michaud next claims that the court erred in finding him guilty of manslaughter in violation of 17-A M.R.S.A. § 203 because the evidence was not sufficient to prove the element of “recklessness.”
8
We review the sufficiency of the evidence “in the light most favorable to the State to determine whether a trier of fact rationally could find beyond a reasonable doubt every element of the offense charged.”
Chad B.,
[¶ 12] Reckless manslaughter consists of “[r]ecklessly ... causing] the death of another human being.” 17-A M.R.S.A. § 203(1). Recklessness involves a conscious disregard of risk that grossly deviates from “the standard of conduct that a reasonable and prudent person would observe in the same situation.” 17-A M.R.S.A. § 35(3) (1983 & Supp.1998). 9 When viewing the evidence in the light most favorable to the State, it is reasonable to infer from the record that Michaud forcefully caused Maki to fall on his back and strike his head on rocks and that Maki inhaled water while Michaud straddled him and held his head under water. 10 Such behavior certainly involves a eon- *1229 scious disregard of risk that grossly deviates from a reasonable and prudent standard of care, particularly in light of Michaud’s size advantage over Maki.
[¶ 13] The court found that “Michaud acted in conscious disregard that his actions created the risk of death to Maki, and his actions were a gross deviation from how a reasonable and prudent person would act under the circumstances.” Upon “[viewing the evidence in the light most favorable to the State and drawing all reasonable inferences therefrom,” the evidence was clearly sufficient to support a finding of recklessness beyond a reasonable doubt.
Wells,
C.
[¶ 14] Michaud also claims that the evidence was insufficient to prove causation beyond a reasonable doubt. The court found that Michaud caused Maki’s death because the death would not have occurred but for Michaud’s conduct. When viewed in the light most favorable to the State, the medical evidence, Michaud’s three conflicting stories, and his emotional behavior and jealousy toward Maki all support a reasonable inference that Maki would not have died but for Michaud’s conduct.
See Chad B.,
D.
[¶ 15] Michaud further contends that the court erroneously concluded that the evidence was not sufficient to raise the issue of self-defense. 11 He argues that, in reaching its decision, the court misconstrued and improperly applied 17-A M.R.S.A. § 101(1). 12 As a result, Michaud claims, the court erroneously excused the State from the burden of proof that section 101(1) imposes.
[¶ 16] “A person is justified in using deadly force on another when the person reasonably believes that another person is about to use unlawful, deadly force against the person or a third person.”
State v. Sullivan,
Pursuant to 17-A M.R.S.A. § 101(1) (1983), the State must disprove beyond a reasonable doubt any statutory defense “in issue as a result of evidence admitted at the trial which is sufficient to raise a reasonable doubt on the issue.” A defense is “in issue” within the meaning of section 101 if the evidence is “sufficient to make the existence of all the facts constituting the defense a reasonable hypothesis for the factfinder to entertain.” Either the State or the defense may introduce evidence that generates the State’s obligation.
State v. Case,
1.
[¶ 17] In determining whether the evidence is sufficient to raise the issue of self-defense, “[a trial] court must view the evidence in the light most favorable to the defendant.”
See Sullivan,
[¶ 18] Michaud’s third statement
13
to the police is sufficient for a court to entertain a “reasonable hypothesis” that Michaud acted in self-defense, if viewed in the light most favorable to him (i.e., assuming he told the truth, despite his two earlier conflicting versions).
See State v. Begin,
2.
[¶ 19] After concluding that sélf-defense is “in issue,” a court must determine whether the State has met its burden of disproving self-defense beyond a reasonable doubt.
See Case,
[¶ 20] Error in a criminal prosecution is only' harmless if it is “highly probable that the error did not affect the factfinder’s judgment.”
State v. Jordan,
III.
[¶ 21] Michaud claims that the court’s written order on his motion for further findings of fact was erroneous because it did not specifically address every finding of fact and conclusion of law that he requested. Although he concedes that there is little Maine law to support his contention, he claims that the use of the word “shall” in M.R.Crim. P. 23(c) 14 “creates a mandatory duty for the *1231 [court] to respond to a request for findings on issues that are not covered within the written decision.”
[¶ 22] Rule 23(c) requires a trial court to make specific findings of fact upon request.
15
See
M.R.Crim. P. 23(c). However, Rule 23(c) does not require a court to specify all the evidence it relied on in making its findings of ultimate fact.
See State v. Levi,
[¶ 23] The elements of reckless manslaughter are that:
(1) the defendant acted recklessly, by consciously disregarding a risk ...; (2) this disregard ... of a risk rises to a gross deviation from the standard of conduct that a reasonable and prudent person would observe in the same situation; and (3) the defendant’s reckless ... conduct caused a death.
State v. Bennett,
IV.
[¶ 24] Finally, Michaud claims that the court’s sentence contains a “facial jurisdictional infirmity recognizable on direct appeal” because the court set the basic period of incarceration in a range of nineteen to twenty years, rather than a definite term of years. Michaud contends that 17-A M.R.S.A. § 1252-C “contemplates a specific term [for the basic period of incarceration,] rather than a range of years.” As we said in
State v. Ardolino,
a range of years rather than a definite term is not a misapplication of principle and does not require vacation of a sentence.
See State v. Ardolino,
The entry is:
Judgment affirmed. Sentence affirmed.
Notes
. Section 203 of Title 17-A states, in relevant part:
1. A person is guilty of manslaughter if that person:
A. Recklessly, or with criminal negligence, causes the death of another human being[;]
17-A M.R.S.A. § 203(1) (1983 & Supp.1998).
.
See Miranda v. Arizona,
.
"Corpus delicti"
literally means “body of the crime,” and consists of two elements: (1) the fact of the victim’s death; and (2) the existence of a criminal agency responsible for the death. Field & Murray,
Maine Evidence
§ 801.9 at 403 (4th ed.1997) [hereinafter Field & Murray];
State v. Reed,
. Since the fact of Maki's death is not in dispute, only the second element of the corpus delicti (i.e., criminal agency) is at issue on appeal.
. (Pursuant to the M.R. Evid. 801(d)(2) hearsay exclusion.)
. Caveat: As Field & Murray noted:
Proof of corpus delicti as a legal prerequisite to admissibility of a criminal defendant’s confession or admission does not mean that the corpus delicti must necessarily be established before the confession can be received at the trial. There is a "strong preference” for proof of the corpus delicti before actually admitting any inculpatory statement of the defendant. However, the trial court's discretion under Rule 611(a) as to the order of proof can extend to permitting the introduction of an inculpatory statement subject to later proof of corpus de-licti.
Field & Murray § 801.9 at 404 (citing
State v. Snow,
.Field & Murray notes that ”[t]he 'probable cause’ aspect of the corpus delicti rule can be established by any kind of evidence which will *1228 support the inference that a criminal act actually was committed.” Field & Murray § 801.9 at 404.
. Although either recklessness or criminal negligence may support a manslaughter conviction pursuant to section 203 of Title 17-A, the trial court only focused on recklessness, and did not discuss whether Michaud was criminally negligent. See 17-A M.R.S.A. § 203.
. 17-A M.R.S.A. § 35(3) (1983 & Supp.1998) defines recklessness as follows:
3. “Recklessly.”
A. A person acts recklessly with respect to a result of his conduct when he consciously disregards a risk that his conduct will cause such a result.
B. A person acts recklessly with respect to attendant circumstances when he consciously disregards a risk that such circumstances exist.
C. For purposes of this subsection, the disregard of the risk, when viewed in light of the nature and purpose of the person’s conduct and the circumstances known to him, must involve a gross deviation from the standard of conduct that a reasonable and prudent person would observe in the same situation.
.Michaud claims , that the State has failed to prove beyond a reasonable doubt the underlying facts supporting the inference that Michaud acted recklessly. Michaud cites
State v. Flash,
. 17-A M.R.S.A. § 108 (1983 & Supp.1998) provides in pertinent part:
2. A person is justified in using deadly force upon another person:
A. When the person reasonably believes it necessary and reasonably believes such other person is:
(1) About to use unlawful, deadly force against the person or a 3rd person;
C. However, a person is not justified in using deadly force as provided in paragraph A, if:
(1) With the intent to cause physical harm to another, he provokes such other person to use unlawful deadly force against anyone;
. Section 101(1) provides, in pertinent part:
The State is not required to negate any facts expressly designated as a “defense,” or any exception, exclusion or authorization that is set out in the statute defining the crime by proof at trial, unless the existence of the defense, exception, exclusion or authorization is in issue as a result of evidence admitted at the trial that is sufficient to raise a reasonable doubt on the issue, in which case the State must disprove its existence beyond a reasonable doubt....
17-A M.R.S.A. § 101(1) (1983 & Supp.1998).
. In Michaud’s first two conflicting statements, he claimed that Maki slipped and fell in the water, and that Michaud was unable to save him from drowning. In his third statement, Michaud conceded that an altercation broke out between them, but claimed he acted in self-defense.
. Rule 23(c) governs trials without a jury in the Superior Court and provides:
*1231 In a case tried in the Superior Court without a jury the court shall make a general finding and shall in addition on request find the facts specially. If an opinion or memorandum of decision is filed, it will be sufficient if the findings of fact appear therein.
M.R.Crim. P. 23(c) (emphasis added).
. The purpose of Rule 23(c) is to “enable the requesting party, and the appellate court on review, to ascertain the factual and legal bases for the court’s decision.”
