Tyquan Tyler was 13 when he was killed on June 24, 2012, in Chicago. He had been at a party with his 19-year-old sister in the 6200 block of South Rhodes Avenue when a fight broke out about 1:20 a.m. As Tyquan and his sister tried to leave, a passing vehicle fired shots; Tyquan was struck in the chest, collapsed on the sidewalk, and was pronounced dead at 3:05 a.m. at the University of Chicago Comer Children’s Hospital. An autopsy confirmed a gunshot wound to the chest and his death was ruled a homicide.

Investigators later arrested 23-year-old admitted gang member Nasean Flowers; court records say Flowers and another attacker had been involved in a fight with members of another gang, entered an alley where Tyquan and others were standing, and Flowers fired two shots toward the group, striking Tyquan. Witnesses reported seeing Flowers running from the alley with the gun. A co-defendant, Dewayne Chester, testified against Flowers and pleaded guilty to conspiracy.

Tyquan had been living with a relative in East Moline to escape neighborhood violence but was home for a summer visit of about two weeks before the shooting. Does anyone have information about the events that night or knew Tyquan and his family?
