Evin Paulos, 25, was found dead in a vacant lot near Cave Creek and Pinnacle Peak roads in Phoenix on June 3, 2017. His family, who had emigrated from Iraq when he was four, learned that Paulos had been stabbed about 30 times.

Investigators say Paulos had been seen leaving with Michael Anthony Arredondo earlier that day. The two reportedly had been friends and neighbors who’d recently fought; Paulos believed their dispute was resolved. An argument during the car ride allegedly continued onto the street, where Paulos was fatally stabbed and Arredondo fled the scene.

Many questions remained for Paulos’s family after the case cooled and the suspect stayed at large. If anyone knew Paulos, his routines, or has information about what happened that day, please come forward to help provide answers.
