A 13-year-old boy is behind bars in juvenile hall, accused of shooting three other teenagers in Fontana this week, one of whom died at the scene. The shooting left an 18-year-old dead and sent two younger boys, ages 12 and 15, to the hospital with gunshot wounds before they were treated and released.
The shooting happened Wednesday in the 9900 block of Cypress Avenue, according to CBS News, which reported the gunfire erupted at roughly 6:10 p.m. A separate account from KTLA put police response to reports of the shooting at around 6:11 p.m. When investigators arrived, they found three boys with gunshot wounds — ages 12, 15 and 18.
The 18-year-old died at the scene, while the two younger victims were taken to the hospital and later released, the station's report states. Fontana police arrested the 13-year-old suspect and booked him into juvenile hall on a murder charge. No motive, weapon type, or details about how the suspect may have obtained a firearm have been established, and the evidence does not establish the identities of the suspect or the victims or their relationships to one another, per the same account.
Investigators Still Seeking Information From the Public
Fontana police are asking anyone with information about the shooting to contact Detective Samuel Saenz by phone at 909-854-8106 or by email at [email protected], per the department's request relayed in the CBS report. No court hearing date or further detention details beyond the juvenile-hall booking have been confirmed.
This is not the only case in recent memory involving a young teenager accused of gun violence in Fontana. In a separate incident at Veteran's Park, two men in their 50s were shot, leaving one dead and one injured, according to ABC7. Authorities said in that case several juveniles from a gang confronted the victims and a 14-year-old boy opened fire; four boys ranging in age from 13 to 15 were identified by detectives as being present. Police arrested the 14-year-old for homicide and a 15-year-old for a probation violation in that case, ABC7 reported.
State Scrutiny of Juvenile Gun Violence Continues
California's Office of Gun Violence Prevention has in recent months pushed resources aimed at reducing shootings statewide. In March, the office published reports focused on supporting the use of Gun Violence Restraining Orders to prevent mass shootings and other gun violence incidents, according to the California Department of Justice, Office of the Attorney General. The same office also lists a revised Ghost Gun Laws Reference Guide, dated December 2025, among its resources.
Cases involving teenage suspects accused of serious violent crimes in California can also intersect with state juvenile justice law. Under California Legislative Information's text of SB 1391, the law amends Section 707 of the Welfare and Institutions Code relating to the fitness of juveniles for juvenile court proceedings. No information in this case indicates how, or whether, that statute applies to the 13-year-old's booking.
No further details about the investigation, including a motive or the identities of those involved, have been released as of Thursday.
