SAN FRANCISCO (AP) — Police have arrested two more people in connection with the fatal shooting of a man a San Francisco couple suspected was pimping and beating their daughter.

The San Francisco Chronicle reports that 26-year-old Antonio Gilton and 35-year-old Alfonso Williams will be charged with murder, conspiracy to commit murder and possessing a firearm as convicted felons.

Police initially said 38-year-old Barry Gilton and his girlfriend, 37-year-old Lupe Mercado, murdered 22-year-old Calvin Sneed after learning their 17-year-old daughter might be working as a prostitute for him. Sneed was shot in his car on June 4.

The pair pleaded not guilty. Their relationship to the two men arrested Wednesday is not clear

Attorneys for the couple say Sneed had been pimping the girl, but say the couple did not kill Sneed.
