Naren Prabhu, 54, and his wife Raynah Prabhu, 53, were shot to death in their Willow Glen, San Jose, home on May 3, 2017. Their 20-year-old son called police about 9 p.m. reporting his parents had been shot. Officers found Naren dead in the front doorway; the couple’s 13-year-old son was inside and later released unharmed by the suspect during a standoff.

Authorities say the shooter was Mirza Tatlic, 24, of Campbell, the ex-boyfriend of the Prabhus’ daughter. Tatlic reportedly had a history of domestic violence and mental illness, and the daughter had an active criminal restraining order against him. During the standoff Tatlic refused to surrender and at one point pointed a handgun at officers, prompting Officer Jacob Morris to fire at least one round that killed Tatlic.

The Santa Clara County District Attorney’s Office and the police homicide unit investigated the killings, while internal affairs, the City Attorney’s Office and the Office of the Independent Police Auditor monitored the case. What details about the events that evening or the lead-up to the attack might someone with information provide?
