Jonathon D’wayne Parker was 16 when he was shot in the parking lot of Deer Valley High School in Antioch, California, shortly before 9 p.m. on January 31, 2020. Nicknamed John John, he had attended a basketball game that evening and was struck three times; he died of his injuries the next day.

The Antioch Police Department opened an investigation into the shooting. Friends and family remembered Jonathon as a gentle giant who didn’t often attend such events but had chosen to watch the game that night; the community held vigils and fundraisers in his memory.

What did anyone who was at Deer Valley High that night see or hear that could help investigators bring Jonathon’s killers to justice?
