On September 11, 2024, at about 5:05 p.m., officers responded to a shooting at a business in the 6900 block of Jurupa Avenue in Riverside, California. Officers found 45-year-old Adrienne Johnson inside her vehicle with multiple gunshot wounds; she was pronounced dead at the scene.

Investigators from the Robbery-Homicide Unit, assisted by the Forensics Unit and the Riverside County Sheriff-Coroner’s Office, identified Adrienne’s brother, 51-year-old David Johnson, as the primary suspect. Evidence and witness accounts indicated David approached Adrienne as she was getting into her car after work, shot her multiple times, and then fled. On the morning of September 13, detectives with the METRO Team located and arrested David Johnson. He was booked into the Robert Presley Detention Center on charges of first-degree murder with a special-circumstance allegation of lying in wait and with gun and great-bodily-injury enhancements; he is being held without bail.

The motive remains under investigation. Anyone with information is asked to contact Detective Stanley Hua at (951) 353-7135 or Detective Nic Cantino at (951) 353-7104, or submit an anonymous tip through the Riverside Police Department’s Atlas 1 mobile app. Would anyone who knew Adrienne or saw the area that evening please come forward?
