The defendant, Richard Rodriquez, was convicted by a jury of vehicular homicide, § 18-3-106, C.R.S.1973 (1978 Repl.Yol. 8) and vehicular assault, § 18-3-205, C.R.S. 1973 (1978 Repl.Vol. 8). He contends that there was insufficient evidence to sustain the conviction, that the trial court abused its discretion by limiting his closing arguments to 30 minutes, that the trial court erred in failing to make factual findings concerning his motion to suppress blood sample results and statements, and that the blood sample and statements were taken in violation of his constitutional rights. Finding error in the failure to make factual findings, we remand for further proceedings.
The record reveals the following uncon-troverted facts. On the afternoon of November 15, 1977, Rodriquez, Joe Tree, and Ernest Archuleta left a bar in Arboles and *859 drove north toward Ignacio. The driver failed to negotiate a сurve in the road, and the car crashed in a field. Rodriquez and Tree were seriously injured, and Archuleta died as a result of injuries sustained during the aceident.
Rodriquez and Tree were taken to a hospital, and the Colorado State Patrol officer investigating the accident ordered blood samples to bе taken from both men. On the day following the accident, several officers and a district attorney visited Rodriquez in the intensive care ward of the hospital. Officer Poole told Rodriquez that they were investigating the accident, and asked Rodriquez whether he was driving. Rodriquez said he believed he was driving, and at that point hе was given Miranda warnings and responded to further questioning. The main issue at trial was the identity of the driver of the car.

The defendant contends that the evidence at triаl was insufficient as a matter of law to sustain his convictions for vehicular assault and vehicular homicide. Where the sufficiency of the evidence to support a guilty verdict is challenged, the testimony must be viewed in the light most favorable to the prosecution. If there is sufficient competent evidence еstablishing each of the essential elements of the crime charged, we may not overturn the jury’s guilty verdict despite conflicts in the evidence.
People v. Duemig,
Colo.,
Vehicular homicide occurs when a person drives a motor vehicle while under the influence of an intoxicant, and such conduct is the proximate cause of the death of another. Section 18-3-106(l)(b), C.R.S.1973 (1978 Repl.Vol. 8). Vehicular assault occurs when a person drives a motor vehicle under the influence of an intoxicant, and this conduct is the proximate cause of a serious bodily injury to another. Section 18-3-205(l)(b), C.R.S.1973 (1978 Repl.Vol. 8).
Here, the death certificate of passеnger Ernest Archuleta was admitted into evidence without objection, and a doctor testified concerning the serious and permanent injuries of Joe Tree. It is uncontro-verted that the accident was the proximate cause of the death of Archuleta and the injury to Tree. No evidence was introduced to contradict the results of the blood sample, which indicated that Rodriquez’s blood alcohol level was .312. This blood alcohol level triggered thе operation of the conclusive statutory presumption that Rodriquez was under the influence of alcohol. Section 18-3-106(2)(c), C.R.S.1973 (1978 Repl.Vol. 8).
On the contеsted issue whether Rodriquez was the driver of the car, the prosecution introduced testimony of a witness who saw Rodriquez enter the driver’s seat when the men left the Arboles bar, and testimony of witnesses at the crash scene. Two accident reconstruction experts testified that, in their opinion, Rodriquez was the driver. Trеe testified that Rodriquez was driving, and the jury heard Rodriquez’s tape-recorded statement that he believed he was the driver and that he had leased the car for business purposes.
Linda Rodriquez, the former wife of the defendant, testified for the defense that she had visited Tree in the hospital shortly after the accident and that he had told her he was driving, “more or less.” A defense accident reconstruction expert testified that, in his opinion, Tree was the driver. Although the testimony of these two witnesses conflicted with the testimony of the People’s witnesses, the resolution of such conflicts remains within the province of the jury.
People v. Jones,
II.
Rodriquеz contends that the trial court abused its discretion by limiting closing argument to 30 minutes per side. Limitation of the time for argument is within the discretion of the trial court,
Schell v. People,
*860 III.
The defendant moved to suppress evidence of statements made in the hospital and the results of the blood sample test. The minute order denying the motion to suppress provided:
“The court finds that under the circumstances and the totality of the circumstances, the blood sample taking was reasonablе and would be admissible. The court further finds that the statements made by the defendant were voluntarily given after advisement of his rights and the waiver of those rights.”
Rodriquez contends that the trial court erred in failing to make specific findings of fact. We agree.
The trial court is required to make findings of fact whenever it rules on a mоtion to suppress.
People v. Duncan,
A.
The standard for determining the admissibility of a blood sample was annоunced in
Schmerber v. California,
In
People v. Fidler,
B.
Rodriquez asserts that statements he made while in the intensive care unit at the hospital were inadmissible because he was in custody and did not waive his
Miranda
rights, or, in the alternative, that these statements were involuntary.
Miranda
warnings are required if the defendant is in custody at the time of the interrogation.
Miranda v. Arizona,
Even if Rodriquez was not in custody when he was questioned, his statements would be admissible only if the People established by a preponderance of the evidence that they were voluntary.
People v. Fordyce,
Colo.,
IV.
The cause is remanded for further proceedings to enable the trial court to make the requisite findings; the record shall then be recertified to this court for further review of the trial court proceedings.
