Pittsburg murder investigation nets nine arrests

CONTRA COSTA COUNTY – An investigation into a fatal shooting earlier this summer in Pittsburg resulted in the arrests of nine people Monday, but at least one other suspect remains at large, police said.

The Pittsburg Police Department worked with other local and federal law enforcement agencies to serve 10 warrants shortly after 5 a.m. in the cities of Antioch, Oakley, Pittsburg and Pleasant Hill, the police department said in a news release.

Nine people were arrested on suspicion of crimes including murder, as well as for firearms violations and drug-related offenses, police said, adding that many of them are believed to be directly involved in or associates of an East Contra Costa County gang.

The warrants stemmed from an investigation into a fatal shooting on July 14 in the 2100 block of Crestview Drive. Police said several suspects shot into a moving vehicle, killing Trevon Richardson, 24, of Antioch, and seriously injuring another man.

At least one other suspect is still being sought in connection with the shooting. Amen Syrius Allen, 19, of Pittsburg, should be considered armed and dangerous, police said.

Anyone with information related to the case can contact Pittsburg police Detective Miguel Gutierrez at 925-252-4095 or the police department’s tip line at 925-252-4040.
