Three Homicide Cold Cases Filed as a Result of Years-Long Operation by FBI Safe Streets Task Force

Martinez, Calif. – Today, the Contra Costa County District Attorney’s Office is announcing three homicide cold cases, involving multiple defendants who are gang members affiliated with the Sureños, were filed recently. The gang violence was focused in South Concord and near Monument Boulevard. This successful effort was due to the years-long investigation and operation led by the FBI Safe Streets Task Force and local partners, including Concord Police, FBI, U.S. Attorney’s Office of Northern California, Bureau of Alcohol, Tobacco & Firearms along with our Office. Two cases were filed last week and one was filed yesterday, totaling four homicides involving 11 defendants.

Operation Boulevard Blues culminated in a major law enforcement operation last Thursday that resulted in the arrest of 31 individuals and involved 31 different law enforcement agencies. Thirty-four search warrants were executed in multiple locations across Contra Costa County and 42 firearms were recovered. The details of the operation were announced earlier this morning with our federal partners.

The operation recovered over 70 firearms, including a machine gun, an AK-47 with 100 round drum, suspected firearm suppressors.

“Our local efforts working collaboratively with our law enforcement partners, especially Concord Police, will keep our community safer and take violent gang members off the streets of Concord,” said District Attorney Diana Becton. “This successful operation started with a wiretap and led to multiple gang members involved in senseless murders and violence being arrested. While these cases were not solved right away, Concord Police and the FBI Safe Streets Task Force did not give up and fortunately we can bring some closure to the victims’ families.”

Overall, the DA’s Office filed three separate homicide complaints involving the following gang members of the Sureños – all of the alleged four homicides were done for the benefit of the gang:

•      People v. Michael Valdez, Andrew Cervantes, Daniel Rodriguez, Docket Number 01-194377-8

The criminal investigations because of this operation are still active and ongoing. All of the defendants charged by the DA’s Office remain in custody.


  1. When you give money to people at the Monument and Sun Valley freeway ramps it goes directly to these gangs through drug purchases. Please stop.

  2. We all are part of problem since we see how they sale drugs and we don’t report to police nice job from police bad job from us

  3. They been on monument for years. I think alot of people fail to see this investigation has been ongoing for at least 5 years. There’s nothing going on on plain sight on monument right now….I live there. 🙄
