OAKLAND — An Oakland man was arrested and charged with murder last month in connection with a December shooting outside a restaurant in San Leandro, court records show.

Wavonte Oxner, 28, was charged with murdering and robbing 23-year-old Laquan Matthews outside of the Little Namking restaurant on East 14th Street in San Leandro. He has not yet entered a plea, according to court records.

According to authorities, Matthews was robbed of a gold chain, which prompted a shooting between two groups of people. Oxner was identified as a suspect after he returned to the scene looking for his car keys. He reportedly explained to police that his car was parked in the restaurant parking lot, and said he dropped the car keys while ducking for cover after the shooting began.

But through witness statements identifying one of the robbers wearing a shirt that said “Fake Friends” and surveillance video of Oxner wearing such a shirt at the scene, detectives identified him as one of the people who attacked Matthews, prompting the shootout. The charging records allege that Oxner “personally used a firearm” to kill Matthews.

Police later determined that Oxner and Matthews were both “associated” with rival gangs in Oakland, according to a police probable cause statement filed in court. When Oxner was arrested Feb. 17, he denied involvement in the crime and invoked his right to remain silent, police said.

Police identified a second suspect, a 23-year-old man, and arrested him last month on suspicion of a parole violation, at a residence on Fruitvale Avenue in Oakland. He has not yet been charged in connection with the homicide, court records show. Both he and Oxner are in Santa Rita Jail in Dublin on a no-bail hold, records show.
