Terrill Marquis Thomas, 20, was shot and killed on June 2, 2012, at about 10:50 p.m. at a triplex in the 700 block of East Columbia Avenue in Pomona, California. Coroner records list him as one of two men fatally shot at the scene; the other victim was 20-year-old Laderrick Lee Rogers. Both suffered gunshot wounds to the chest and were pronounced dead at the scene.

A third victim, identified as Thomas’ father, Vincent Dean, was critically injured and taken to L.A. County-USC Medical Center. The victims had been visiting a tenant in the triplex when the shooting occurred. The building owner, Greg Estel, said two law students in another unit narrowly escaped injury when a bullet came through their window and landed in a box of cereal. Police were also investigating a hit-and-run about six minutes after the shooting and under two miles away that sent at least one person to a hospital.

Investigators reported few clues, no identified suspects, and an unclear motive. Anyone with information is asked to contact the Pomona Police Department or Crime Stoppers anonymously. Did anyone in the area at the time see or hear anything that could help the investigation?
