Four ambush-style killings and prison violence all stemmed from North Richmond gang war, police say

RICHMOND —  Contra Costa prosecutors have filed murder and conspiracy charges over three previously unsolved Richmond killings and an Oakland homicide, all ambush-style shootings that police have attributed to one of the Bay Area’s oldest and deadliest gang wars.

Rondell Fluker, 27, of Vallejo, along with Santa Clara resident Joseph Westbrook, 27, and Richmond resident Lavaiza Hill, 28, have been charged with murder, conspiracy and gun possession. Westbrook and Fluker were charged last year.
