Morgan Rockwell Fincher was 40 when he was shot and killed on the east side of Tucson on the night of Saturday, July 31, 2021. Police responded to the 8100 block of East Mountvale Drive and found Fincher with gunshot injuries; he was treated at the scene and then pronounced dead.

Detectives focused quickly on a suspect and within a couple of days the Tucson Police Department arrested Gabriel Valenzuela. Investigators determined the shooting was not random but resulted from an argument that escalated; Valenzuela was booked into the Pima County Jail on a charge of second-degree murder.

The relationship between Fincher and Valenzuela and what triggered the argument are central unanswered questions in the case. If anyone knew Morgan, saw him in that neighborhood that night, or has information about the argument, please come forward.
