Kevin C. Jarrett, 31, was shot and killed on June 30, 2017, in University Park, Illinois, after arranging a sale through the LetGo app. The meeting took place about 10:45 p.m. in the 800-block of White Oak Lane, a townhome area. Jarrett was with his girlfriend, who was not injured; she tried to drive him to safety but the car stopped a few blocks away at Burnham Drive, where Jarrett died.

University Park Police identified three suspects described as wearing all black, including a juvenile with an Afro hairstyle, and worked with LetGo to trace the victim’s account and the transaction. Jarrett, known to friends and family as K.C., was a father of three who worked with his father at a seasoning company in Momence; his relatives said he was peaceful and did not normally go to University Park.

Anyone with information about the shooting is asked to contact investigators.
