On the afternoon of September 23, 2014, 19-year-old Pedro Antunez-Andrade was found in Phoenix near 9800 North 9th Avenue with a fatal gunshot wound. Phoenix police had been dispatched around 1:40 p.m. after reports of a shooting and discovered Antunez-Andrade at the scene.

Investigators quickly identified a primary suspect, a 15-year-old named Iram Quintana, and established probable cause leading to an arrest warrant. Authorities believed Quintana had fled to Mexico, and efforts to locate him by the county attorney’s office and the U.S. Marshal’s Office were unsuccessful, leaving the case cold for years.

What details about that day or that neighborhood might help explain how Quintana was thought to have left the area, or who else might have been present near 9800 North 9th Avenue around 1:40 p.m. on September 23, 2014?
