On the evening of September 3, 2014, 19-year-old Jonathan Torres was on the porch of his Prospect Street home in Enfield, Connecticut, when he was shot in the chest. He was taken to a Springfield, Massachusetts medical center and pronounced dead. Friends and family remembered him as a good kid who was a few credits shy of graduating high school.

Witnesses said three people fled in a tan Toyota Camry that was later found to have been stolen. Police located the car off Interstate 91 South and found a loaded handgun and brass knuckles inside. Four teenagers were arrested at the scene: Takai Brown, 18, Cheyenne Concepcion, 18, and two minors aged 16 and 17.

Prosecutors said the attack was a robbery planned to take Torres’s iPhone and headphones. By August 2015 several of those involved pleaded guilty to felony murder or robbery, and October 2015 brought prison sentences for the defendants. Does anyone have information about Torres, his last evening, or the people involved that could help clarify unanswered details?
