Martin MacNeill was hospitalized after taking apart a disposal razor and attempting to cut the femoral artery in his leg.
"He was discovered early enough by guards so his injuries were not life-threatening," Sgt. Spencer Cannon of the Utah County Sheriff's Office told ABCNews.com.
The Mormon doctor is expected to recover but will remain in the hospital overnight and there's a chance he'll stay through the weekend.
"Obviously, he was experiencing some emotional turmoil. He's post-conviction, but pre-sentence, and he's facing the possibility of spending the rest of his life in prison. So in our mind, that creates a lot of emotional stress," Cannon said in a press release.
"Sometimes, people facing a sentencing like this question whether they should even exist. It's a very vulnerable time… He was not under direct observation 24/7, but there are regular checks that need to be done. They found him in the midst of the attempt to kill himself."
Inmates at Utah County Jail are typically given 15 minutes of access to disposal razors for hygiene purposes, Cannon revealed.
