New court records dispute the motive of a deadly stabbing in Phoenix.

When Olin Coho, 38, talked with ABC15 he said he stabbed a man “in the heart” because the victim aggressively tried to take over the suspect’s sleeping area around 8 p.m. on October 14.

He also stated, in a jailhouse interview, that he felt physically threatened by Robert Prewitt because he thought he had a knife. Coho, who is homeless, also said in his interview that he had made up a space near 18th and Peoria Avenues, he had been drinking and was ready to sleep. 

Coho said in his interview that Prewitt tried to move him from his space, so with. “No hesitation, [I] just took out my knife [and] stabbed him right in the heart.”

The court records obtained Thursday by ABC15 indicate a different motive for the stabbing.

According to a witness, Prewitt was making fun of Coho for urinating on himself. That’s when, according to the witness, Coho walked up and stabbed Prewitt. The witness told police that he urged Coho to stay with Prewitt while he got help. Coho allegedly replied, “Let him die.”

Police arrested Coho the next day. He reportedly admitted stabbing Prewitt because he was being made fun of for urinated on himself. He also allegedly admitted to police that he knew Prewitt was not armed and that stabbing him was wrong.  

“I’ve been dreaming over and over about what I did,” Coho said, adding that he regrets killing Prewitt and apologizes to the victim’s family.

Coho has been charged with second degree murder.
