Darell Alviar Esguerra, 25, was killed on August 10, 2014, during a family birthday party at a home in Tracy, California. Witnesses said armed men drove up, two exited with handguns and confronted family members; investigators say about 20 shots were fired into the house. Esguerra was struck in the back of the head, found unconscious by officers, and died at San Joaquin General Hospital about two hours later.

Police described the incident as an apparent robbery attempt. Three men from San Jose — Terrence Boone, Christon Jones and Sedrick Hutchinson — were arrested in connection with the case; Boone was taken into custody during a traffic stop in Milpitas, and Jones and Hutchinson were arrested in San Jose. The suspects faced charges that included murder, attempted murder and robbery, and Boone was also charged with intentional and personal discharge of a firearm with great bodily injury.

Family members said Esguerra may have been trying to protect his cousin Jerick Bali when he was shot. The killing, Tracy’s first homicide in nearly two years, prompted community fundraising for the family and calls for justice. Does anyone have additional information about the night of August 10, 2014, or about the people involved?
