Arturo Gastelum, 24, was shot after an argument at a residence in the 4600 block of South Calle Jon in Tucson on November 7, 2025. After being wounded, Gastelum tried to leave in his vehicle but was found shortly afterward in his car off the roadway near South Campbell Avenue and East Irvington Road. First responders pronounced him deceased at the scene.

Police located and arrested 21-year-old Jerome Middleton III on November 8, 2025. He was booked into jail and faces a charge of second-degree murder in connection with Gastelum’s death.

Is there anyone who saw the argument or the vehicle as it left the residence who can help fill in what happened that night?
