Juan Perez-Jimenez, 22, was found shot to death inside his 1997 Mercury sedan on March 15, 2014. The car was parked in a dirt area near the intersection of Stanfield and Miller roads, next to the Nissan Technical Center North America proving grounds in Stanfield, Arizona. A passerby with no known connection to Perez-Jimenez discovered the vehicle and called authorities around 5:19 p.m.; deputies from the Pinal County Sheriff’s Office found him in the front seat and determined he had been shot earlier that day.

The sheriff’s office asked the public for help in the weeks afterward and urged anyone with information to contact them or leave an anonymous tip with Silent Witness. No arrests have been publicly announced and the case is now considered a cold, unsolved homicide; there is no public information about suspects or persons of interest. If anyone knew Juan, saw him in the Stanfield area that day, or has information about the car or its movements, please come forward.
