On March 22, shortly after 9:00 PM, officers responded to a convenience store on the 1000 block of Power Avenue. There, 44-year-old Abdul Raouf, a store clerk, was found suffering from gunshot wounds and unfortunately did not survive.

Through the investigation, it was learned that while in the store, Jessica Russo had a disagreement with another store clerk. Shortly after the disagreement, Gregory Rossignon entered the store and shot Abdul for no apparent reason.

Both Rossignon and Russo fled after the shooting.

As the investigation progressed and detectives searched for the suspects, on March 29, Jessica Russo was located and arrested during the service of a search warrant at a residence in Antioch.

Last night, detectives received information that Gregory Rossignon had fled to Modesto and was hiding in an apartment. Working with the Modesto Police Department and their Tactical Team, a search warrant was served shortly after 7:00 AM. During the service of the warrant, it was determined that Rossignon was in the apartment but refused to come outside. After several hours of negotiating with the Modesto Police Departments Crisis Response Unit, Rossignon peacefully surrendered. Rossignon was brought back to Pittsburg and will be booked into Contra Costa County jail for murder.

We would again like to thank community members in Pittsburg, Antioch, and now Modesto for their cooperation and patience while pursuing these suspects. We would also like to thank the U.S Marshals Service, the Modesto Police Department and all their staff for the dedication and resources that led to Rossignon’s arrest.
