On the evening of November 17, 2015, 27-year-old Thomas Lacolla of Riverhead, New York, was fatally shot while sitting in a car in the Riverside hamlet. The attack happened about 9:37 p.m. outside a residence on Old Quogue Road. Multiple shots were fired into the vehicle; Lacolla was pronounced dead at the scene. Numerous witnesses called 911 and some reported hearing as many as 20 to 30 shots.

Investigators later determined Lacolla was not the intended target. He had been sitting in a car that belonged to a rival gang member, Trendell Walker, who was not in the vehicle when the shooting occurred. The shooting was carried out by members of the Red Stone Gorilla set of the Bloods, who had an order to kill that rival. Several people involved were arrested: Jason Langhorn was identified as one of the shooters, pleaded guilty to a firearms-related murder charge in August 2021 and in November 2022 received a 27-year federal sentence followed by three years supervised release; Terrill Latney, the getaway driver, pleaded guilty to racketeering including participation in Lacolla’s murder and was sentenced to 20 years; the gang leader Jimmy Dean was indicted and pleaded guilty to racketeering; and Nicholas Sokol was charged with witness tampering for threatening a cooperating witness.

Does anyone have information about Thomas Lacolla’s movements that night or about activity on Old Quogue Road in Riverside around 9:30 p.m.?
