James Daniel Maciulla, 34, was found shot inside his vehicle and pronounced dead at the scene just after 1 a.m. on August 14, 2025, in William Land Park near the 1200 block of 13th Avenue and West Land Park Drive in Sacramento. Officers initially responded to a medical call about a crash and discovered Maciulla with at least one gunshot wound; detectives were working to determine whether the shooting occurred before the crash and how the two events were connected.

Friends and family described Maciulla as a Vacaville man who regularly came to Sacramento for work and family, and they said the apparent randomness of the attack has been devastating. Investigators characterized the shooting as appearing isolated and asked the public for help as they canvassed the area and gathered leads. The arrest of 36-year-old Jonathan Brito on a murder charge was announced about a month later; authorities did not release a motive and said key circumstances remained under investigation.

Did anyone in or around William Land Park in the early hours of August 14 see or hear anything that could help explain what happened?
