Male, age 13, ethnicity not publicly reported. On March 27, 2025, in Irvine, California, Jonathan Ares Mandegari-Kazemi was gravely wounded by a gunshot and died soon after. His identity and date of death were later confirmed in funeral and obituary notices, while officials described him as a Southlake Middle School student whose passing shook classmates and staff.
That afternoon, Jonathan, age 13, had gone with another boy to visit a friend at a home in the Heathergreen and Weepingwood area. Inside were the three juveniles and a female adult. Investigators determined a handgun had been left unsecured and loaded on a bedroom nightstand belonging to the homeowner, and they recovered numerous other unsecured firearms from the same room. Detectives’ preliminary finding was that the wound was self-inflicted, though they could not immediately say whether it was accidental or intentional.
First responders were dispatched at 2:42 p.m. Officers rendered aid, but the 13-year-old, male, could not be saved and died a short time later. Local reports described a gunshot to the upper body and noted that the victim was a middle-schooler from the area.
The next day, March 28, 2025, police arrested 56-year-old Christian Douglas Yeager of Irvine. Officers said Yeager owned the firearms found in the bedroom and was not home when the shooting occurred. He was booked into Orange County Jail on suspicion of criminal storage of a firearm and child endangerment while detectives continued to investigate the circumstances leading to the shot that killed Jonathan, age 13, male.
Authorities emphasized that the inquiry would determine whether the self-inflicted shot was accidental or intentional. In the meantime, the police department coordinated with the Irvine Unified School District to provide resources to Southlake Middle School and said no further details were expected imminently. The portrait that remains is of a brief, irreversible moment in a friend’s bedroom, a loaded gun left within reach, and a community grappling with the loss of a 13-year-old boy whose day was supposed to be ordinary.
