Benison Tran, 58, and his wife Maria Tran were fatally shot at their home in Dublin, California, on September 7, 2022. The couple’s 14-year-old son and other family members were in the house but were not injured. A 24-year-old Alameda County sheriff’s deputy, Devin Williams Jr., entered the Tran residence around midnight and opened fire, then fled the scene and turned himself in about 11 hours later. Williams was charged with two counts of first-degree murder with special circumstances.

Investigators reported that Williams had a personal relationship with Maria Tran that developed through her work as a hospital nurse and had become strained before the shooting. Court testimony and pretrial filings noted that a psychological evaluation had previously flagged Williams as not suited for duty, though he remained on the job and armed at the time of the killings. The Tran family gave emotional testimony during proceedings about the impact of the loss.

Who in the Dublin community or the hospital where Maria worked might have information about the relationship or the events leading up to September 7, 2022?
