Lillian Gamboa was 31 when she was shot and killed late the night of September 26, 2024, along the south side of Tucson near the 500 block of West Irvington Road. Officers were dispatched just before 11:30 p.m. for reports of an aggravated assault and found her gravely injured from gunshot wounds; Tucson Fire Department medics and officers attempted aid but she was pronounced dead at the scene. Detectives from the Homicide Unit canvassed the area, interviewed witnesses and processed evidence, and initially detained multiple people who had been nearby.

Investigators came to focus on 29-year-old Liam Andrew Devoid, who had been in the area and later reported his vehicle stolen about an hour before the shooting. After forensic testing and follow-up interviews, detectives identified him as a suspect and he was arrested and booked into the Pima County Jail on felony charges including first-degree murder, drive-by shooting and false reporting to law enforcement. Police reiterated that he is presumed innocent until proven guilty and asked anyone with information to contact authorities.

Lillian’s death has also been noted in online memorials and gun-violence listings that mark her age and the date she died. If anyone saw the shooting, the vehicle involved, or has information about that stretch of West Irvington Road that night, please come forward.
