Joseph Garrison, 35, was fatally shot on December 4, 2019, in the 2100 block of Peppertree Way in Antioch, California. Police found him with multiple gunshot wounds and he was pronounced dead at the scene after officers arrived about 11:40 p.m.

Two suspects were arrested in connection with the killing. Vernon A. Louisville, 45, was taken into custody the next day in Vallejo and charged with murder and being a felon in possession of a firearm; the murder charge carries a gang enhancement. Louisville previously faced an attempted murder arrest in July that was later dropped for lack of evidence. Demario Brown, 26, surrendered to police after learning about SWAT operations and was charged with murder and held on $2 million bail. High-risk search warrants were executed in Antioch and Pittsburg as part of the evidence-gathering, though authorities have not disclosed the motive or specific evidence.

Garrison’s death was the 12th homicide in Antioch in 2019. Anyone with information about the killing is asked to contact investigators.
