A large vigil in East Garfield Park on Halloween night, October 31, 2022, ended in a mass shooting that left one man dead and 14 others wounded. Around 9 p.m. in the 800 block of South California Avenue, a vehicle drove past a crowd gathered for a balloon release and people inside the vehicle opened fire. Video shows the car passing and gunmen firing into the crowd before fleeing.

Forty-eight-year-old Pierre Riley was struck in the head and remained on life support for three days without regaining consciousness before he died. Victims ranged from a 3-year-old boy to adults aged 31 to 56; the youngest child was shot in both legs and several victims were in serious or critical condition. Ten of those wounded were from one family.

No arrests have been announced and the motive remains unknown. The police are reviewing video and have offered up to a $15,000 reward for information leading to charges or a conviction. If anyone has information about the shooting or knew Pierre Riley, please share what you know with investigators.
