A Tucson was arrested on suspicion of first-degree murder after a man was shot dead Saturday morning in his house on the city's south side, police said.
Dirk Barret Prather, 34, is accused in the fatal shooting of Clayton Moore Bishop, 44, Tucson police said in a news release.
Bishop was staying temporarily at Prather's house on West 21st Street near South Sixth Avenue, the release said.
Bishop was found shot in the head about 10 a.m., police said. He died later at the hospital.
Prather told a neighbor that he shot a homeless man in self defense. He also claimed Bishop "confessed to a lot of murders," according to an interim complaint filed in Pima County Justice Court.
Prather said he and Bishop were drinking alcohol the night before and at some point Bishop pulled a knife and was "atgonizong" him with it before putting the weapon away, the complaint said. Prather also claimed to have been on "a lot" of Adderall.
"Today, with Clayton, I just woke up and basically shot him in the back of the head because there was some bad bad bad vibes," Prather told an officer.
Prather was booked into the Pima County jail on a $1 million bond.
