Bernardo Marin was 25 when he was killed in a parking-lot shooting on Tucson’s south side on November 23, 2018. The shooting happened just after 4:00 p.m. at 5118 S. 12th Ave., after a verbal dispute involving Marin, a companion, and at least two other men. Marin suffered gunshot trauma and died at the scene; his companion was also struck, drove the vehicle away, and was later found in a nearby neighborhood and taken to hospital with serious injuries.

Police said the killing did not appear to be gang-motivated. Detectives arrested 29-year-old Augustino Martinez on January 11, 2019, on charges that included first-degree murder and aggravated assault; Martinez was already in custody on unrelated charges when served with the homicide warrant. Investigators at the time said they believed others were involved and asked for tips. It is not clear from available reports whether any additional suspects were identified or what became of the prosecution.

Does anyone have information about the incident or about people who were present at 5118 S. 12th Ave. that afternoon?
