Richard D’Ambra, 68, was shot and killed on October 6, 2021, in the 200 block of South Valley Center Avenue in San Dimas while visiting his mother. The shooting happened shortly after 7 p.m. and investigators say it was carried out by his younger brother, Joseph D’Ambra, who was 62 at the time. After the fatal shooting, Joseph went to another location in San Dimas and fired into the car of a different brother; nobody was injured in that incident.

The Los Angeles County Sheriff’s Department identified Joseph as the primary suspect, described him as armed and dangerous, and conducted a manhunt. Deputies later located and arrested him at the San Bernardino Sheriff’s Victorville station; he was booked on suspicion of murder and held without bail at Twin Towers Correctional Facility in Los Angeles. Authorities attributed the violence to longstanding personal issues within the family but did not disclose specific details.

Did anyone in the San Dimas area know the D’Ambra family or have information about tensions between the brothers?
