Those medical crews also attempted to perform CPR and other life-saving efforts before Michele MacNeill was taken to American Fork Hospital, where she was pronounced dead.
During the trial, the jury heard from a number of witnesses, including Willis, several of Martin MacNeill’s daughters — who believe he killed their mother — and two inmates who claimed the defendant confessed the alleged murder to them.
Prosecutors weaved a narrative that focused on Martin MacNeill’s bad or odd behavior — including the growing seriousness of his affair with Willis, his insistence that Michele MacNeill have a face-lift, asking that extra medications be prescribed for the woman and his reaction to his wife’s death — all added up to murder.
"There is a mountain of circumstantial evidence here, ladies and gentleman," Grunander told the jury Friday.
Autopsy » However, the state Medical Examiner’s Office has never ruled the woman’s death a homicide, a fact that Spencer said showed reasonable doubt that Michele MacNeill was murdered.
After an autopsy in 2007, Michele MacNeill’s manner of death was ruled "natural," the result of "chronic hypertension and myocarditis, which are capable of causing acute unexpected arrhythmia and sudden death."
But investigators say Martin MacNeill called the medical examiner multiple times and gave misleading information. In 2010, in a new investigative report, Chief Medical Examiner Todd Grey changed the cause of death to the combined effects of heart disease and drug toxicity. The manner of death was changed to "undetermined."
Martin MacNeill’s attorneys argued at trial that the man had an alibi at the time Michele MacNeill died because he was at work at the Utah State Developmental Center. However, prosecutors pointed out in their closing arguments that there is a window of time — between 9:30 a.m. and 11 a.m. on the day of Michele MacNeill’s death — where Martin MacNeill’s whereabouts are unknown.
Despite the defense’s attempt to establish an alibi, Grunander said that Martin MacNeill had plenty of time to leave work and "take care of business" at home.
"Give Michele the drugs, fix her up a bath, get her in the tub, hold her head down a little while. Help her out," Grunander said, paraphrasing the testimony of an inmate who claims Martin MacNeill confessed the killing to him.
The defense called only four witnesses, including a former co-worker of Martin MacNeill and his child’s kindergarten teacher, to back his alibi theory that he was at work at the time of Michele MacNeill’s death and could not have killed her.
Defense attorneys also brought in an ergonomics expert, who told the jury it would have been difficult for Martin MacNeill to have lifted his wife from the bathtub by himself.
Martin MacNeill did not take the witness stand in his own defense.
