Shawn Chatman, 47, was one of two men shot to death at Cesar Chavez Park in Oakland’s Fruitvale district on the night of August 30, 2016. Authorities found Chatman and 28-year-old Augustine Vigil at the park around 11:09 p.m.; both were pronounced dead at the scene. The two men were reported to frequent the park, but the motive for the killings has not been determined.

Investigators have faced obstacles: no arrests have been announced, no suspect descriptions have been released, and there was no usable surveillance footage from the park that night. A reward of up to $20,000 has been offered for information leading to an arrest. The deaths left families and the community seeking answers.

If anyone has information about who was responsible or about activity at Cesar Chavez Park that night, please come forward.
