RICHMOND, Calif. (KRON) – A man arrested for a Richmond murder last week had been arrested for murder three times before and was on parole after a manslaughter conviction, according to Richmond Police Department.

Bobby Dee Dozier, 37, “has extensive ties to Richmond,” police stated in a press release.

“Bobby Dozier has three previous arrests for murder and was convicted in 2010 of manslaughter,” the press release stated. “He was paroled in September 2020.”

The Richmond Police Department told KRON4 News that the first three murder arrests were in the 2000s decade. It was the third that became the manslaughter conviction. The police spokesperson said the first two murder arrests may not have been charged.

Dozier’s arrest is in connection to the killing of Emari Cook, a 26-year-old from Vallejo who was shot with an assault rifle July 14 around 10 p.m. near South 49th Street and Cutting Boulevard.

“A suspect exited the driver seat of the vehicle holding an assault rifle, confronted Cook and ultimately shot and killed him,” the press release stated. “Casings to an assault rifle were located at the scene and a description of a vehicle was obtained from nearby commercial video surveillance cameras.”

An extensive search of the Highway 4 License Plate Reader system with the assistance of the San Pablo Police Department led homicide detectives to the vehicle believed to have been involved in the crime, and its registered owner.

“The investigation continued that developed additional information linking the registered owner of the vehicle as being the suspect responsible for this senseless murder,” the press release stated. “On October 19, 2022 the Richmond PD SWAT team served a search warrant in the 1300 block of Palm Ave. [in] Martinez, Ca. for additional evidence related to the case. The suspect was located inside of the residence and arrested on an outstanding, unrelated firearm, warrant.

“A search of the residence located two firearms, one a short barreled AR-15 pistol and a semi-automatic handgun with an attached selector switch to make the firearm a fully automatic weapon,” the press release continued.

The crime lab determined the AR-15 was the weapon used in Cook’s killing.

Dozier was charged with one count of murder and firearms violations Thursday by the Contra Costa District Attorney’s office.
