A Utah doctor serving a term of up to life in prison for drugging and drowning his wife so he could carry on an affair with another woman was found dead in the Utah State Prison Sunday.

According to a press release from the Utah Department of Corrections, 60-year-old Martin Joseph MacNeill was found unresponsive in the outdoor yard of the Olympus Facility of the Utah State Prison Sunday morning.

While an investigation will determine the exact cause of death, the press release states there are no "obvious signs of foul play."
