TUCSON – Police have identified the man who was killed at an east side Walmart parking lot on Thursday.

Police say 18-year-old Juan Andres Allen was pronounced dead at the scene. The Tucson Police Department responded to a Walmart store on Speedway Boulevard and Kolb Road just before midnight for reports of a shooting, according to Sgt. Pete Dugan.

Upon arrival, officers located Allen on the ground in the parking lot with “obvious sign of gun-shot trauma,” officials said.

Officers assisted the victim with their aid kits until it was safe for paramedics with the Tucson Fire Department to step in.

Officers received information regarding an SUV fleeing the scene after the shooting. A vehicle, matching the description, was later located in the 8600 block of E. Old Spanish Trail.

Dugan says there were several people inside the SUV and they have been detained. The men have been identified as 19-year-old Eduardo Carranza, 18-year-old Francisco Morales and a 17-year-old juvenile. Reportedly, the three and Allen had gang affiliations.

According to officials, Allen and Carranza exited the SUV armed with handguns. They approached a man sitting in his vehicle, attempting to steal the vehicle. The victim pulled out a handgun of his own and shot Allen multiple times.

Carranza then fled to the SUV, which and left the scene. Police say the SUV was stolen on Feb. 20.

Carranza was arrested and charged with first-degree murder, attempted armed robbery and attempted aggravated robbery. Francisco Morales was arrested and charged with theft of means of transportation.

Anyone with information is asked to call 88-CRIME.
