Raul Romero was 61 when he was fatally shot in Phoenix, Arizona, on August 16, 2015. His death was initially treated as an isolated killing, but detectives later linked it to a broader pattern of fatal street shootings that terrorized a predominantly Latino neighborhood between August 2015 and July 2016.

Investigators eventually arrested 23-year-old Aaron Saucedo, who was initially charged in Romero’s murder. Romero had been in a relationship with Saucedo’s mother, a detail investigators cited when charging Saucedo in Romero’s death. Authorities connected Saucedo to nine murders and other shootings and filed 26 felony counts, including homicide and assault, after community tips and the release of a suspect sketch and a description of a black late 1990s to early 2000s BMW 5 series led to his identification.

If anyone knew Raul Romero, his movements on August 16, 2015, or has information about the shootings in that neighborhood, please come forward.
