Antwana Muhammad, 39, along with her live-in boyfriend, Charles Smith, 32, are suspected of exploiting her 14-year-old biological daughter to perform commercial sex acts throughout Murrieta, the San Fernando Valley and other locations across Southern California.
During the investigation, it was revealed that an adult daughter was also being pimped by both Muhammad and Smith.
It is believed that Smith posted online advertisements soliciting the daughters for prostitution and that Muhammad took them to perform the activities, Sgt. John Sawyer wrote. Muhammad and Smith kept all of the earnings from these activities.
Both Muhammad and Smith were arrested on Thursday afternoon.
Officers spotted Muhammad driving in the area of Ramona Expressway and Interstate 215 before arresting her. They also got a residential search warrant in the 1400 block of Medallion Court in Perris, where they found Smith and took him into custody.
The two are held in the Southwest Detention Center in Murrieta on charges of human trafficking of a minor, pandering a minor and pimping. Charges of child endangerment will also be sought, deputies said.
Bail was set at $250,000.
Muhammad's daughters were taken into protective custody by Child Protective Services.
