Joshua Walters, Peterson's cellmate, was convicted of Assisting Suicide in 2010 and received a sentence of 2 Years, 3 Months to be served after the time he was currently
serving. Peterson's body was found after Walters yelled to a guard that he thought his roommate was dead. Walters told detectives he had nothing to do with the death
and speculated that Peterson may have been feeling down because he had stopped taking his medication. But Walters described his role in the suicide in great detail to
another inmate.
Peterson did not want to commit suicide then because his family was coming for a visit, but Walters persuaded him to do so and said he would also commit suicide after
Peterson did. Walters told Peterson to write a suicide note and put it in his waist band. Walters tied the noose to the bed for Peterson and made sure it would support
his weight by putting his own head inside it. Then he twisted the sheet to open a hole for Peterson. Peterson voluntarily put on the noose, and Walters put a towel
around his neck to help him pass out. Peterson began twitching and kicked a chair, which Walters moved because it made too much noise. Then Walters pretended to go to
sleep in his bed. About an hour later, he called for help.
