Donovan Heard was 19 when he was shot and killed on May 21, 2019, at Memorial Field Park in Antioch, California. Donovan and an 18-year-old companion were in a vehicle at the park when an individual approached and opened fire. Both victims drove themselves to Sutter Delta Medical Center; Donovan died at the hospital and the 18-year-old survived in stable condition.

Investigators say the shooting occurred during an illegal gun transaction at the park, after the suspect and the victims met there to conduct the deal. Donovan’s death was recorded as the city’s fourth homicide of 2019.

Does anyone who was at Memorial Field Park that night or who knows Donovan or his companion have information to share with investigators?
