On Wednesday, August 9, 2023, Contra Costa County deputies conducted a welfare check around 5:20 p.m. at a home on the 100 block of Larkwood Circle in Danville, California, after the father's ex-wife could not reach the family. Inside they found three bodies — 44-year-old Nemanja Isailovic and his two daughters, ages 13 and 11 — all deceased with gunshot wounds.

Notable Details
The welfare check that uncovered the deaths was prompted by family concern: KTVU reports "The welfare check was made after Isailovic's ex-wife couldn't get in touch with them," and that "When authorities arrived, Isailovic's SUV was still parked in the driveway." CBS notes per his LinkedIn he "was a hardware and software engineer who had been working at IXL Learning as a content resource engineer." These details provide meaningful context about the family dynamics (a divorced/separated household) and discovery of the incident.
