Calvin Eugene Gray, 33, was fatally shot on July 29, 2014, while in his vehicle in the 1000 block of West 76th Street in the Vermont Knolls neighborhood of Los Angeles. The shooting happened around 8:30 p.m.; he was off-duty and reportedly dropping off a relative when he was struck multiple times and pronounced dead at the scene.

Investigators say shots were fired from another vehicle, suggesting a possible drive-by shooting. The LAPD Robbery-Homicide Division offered a $30,000 reward for information and continues to seek tips. No arrests have been made and the motive remains unclear. Gray’s family and colleagues remember him as a dedicated security officer who hoped to become a sheriff’s deputy and who regularly fed the homeless; his mother, Margaret Gray, has said she believes the shooting was a setup possibly motivated by jealousy.

If anyone has information about what happened that night or knew Calvin’s movements, please come forward to the LAPD.
