Tre Lorenzo Henry, known as Trixx, was 19 when he was fatally shot on November 1, 2012, in Chicago’s Washington Park neighborhood. He was inside a vehicle at the time of the shooting. Tre’s death was one of more than 500 homicides recorded in Chicago that year, a sharp spike driven in part by gun violence that hit neighborhoods already facing poverty and gang activity.

Family and friends remembered Tre as full of life and kind-hearted; he is commemorated on memorial pages where people shared grief and memories and lit candles in his honor. His killing underscores the vulnerability of young people in these communities and the long shadow violence casts on surviving family and friends.

If anyone knew Tre, saw him that day, or has information about the November 1, 2012 shooting in Washington Park, please come forward with what can help this case.
