Pheonix ? The gunmen took turns as they drove around the city.

Some nights it was Samuel John Dieteman, a burly electrician with a ragged mop of jet black hair. According to court documents, he’d blast at lone pedestrians from the window of a silver Toyota Camry in what he called “random recreational violence.”

Other nights the trigger was pulled by his roommate, Dale S. Hausner, a baby-faced janitor and freelance photographer, the court documents allege.

After each shooting, the pair would drive slowly away, leaving little evidence other than the victim’s body on a sidewalk.

Dieteman, 30, and Hausner, 33, face two counts each of first-degree murder and 14 counts each of attempted first-degree murder. A preliminary hearing is scheduled Aug. 14.

Overall, they are being investigated in 36 shootings, including 17 that targeted people and others that involved animals.
