Dmar Tucker, 39, of Vallejo, was shot and killed in Antioch, California, on October 3, 2020. The shooting happened about 3:54 AM on Hap Arnold Street as Tucker parked and stepped out of his vehicle; he was ambushed and struck multiple times. Officers rendered first aid but Tucker died at the scene.

Investigators identified 32-year-old Kelandre Dunn of Concord as the primary suspect and say the motive involved a love triangle with an unnamed woman. Dunn allegedly lay in wait, fired several shots that struck Tucker, then fled to Stanislaus County. He was later located and arrested in Modesto and charged in Contra Costa County with murder while lying in wait and personal use of a firearm during a murder; he was held without bail.

The Antioch Police Department worked with multiple agencies in the investigation. Does anyone who knew Dmar or witnessed activity on Hap Arnold Street that morning have information to share?
