Barry Gilton and his girlfriend, Lupe Mercado, face murder charges for the death of 22-year-old Calvin Sneed, the San Francisco Chronicle reported.
Sneed was shot and killed on June 4, officials said. Police believe Gilton was the shooter. Investigators said the couple searched for their 17-year-old daughter throughout the state once they found out she may have been working as a prostitute for Sneed.
Officials said Gilton and Mercado may also be responsible for a shooting last month where someone fired into Sneed's car. They're both being held on $2 million bail.
