On the evening of June 21, 2016, 19-year-old Cameron Mounds Jr. was fatally shot on Enfield Street near Greenfield Street in Hartford. The shooting, detected around 7:22 p.m. by the city’s shot-spotter system as two separate volleys of four rounds, was a double homicide that also killed 21-year-old Ashley Spence; a third person, 39-year-old Harold Cook, was wounded and survived.

Hartford police found Mounds with a gunshot wound to the chest and he was pronounced dead at the scene. Spence was shot multiple times in the torso and later died at St. Francis Hospital. Investigators identified a person of interest early on, and detectives treated the case as a priority while they worked to develop evidence and witness accounts.
