RANCHO CUCAMONGA (CBSLA) — Police say an adult film actress and a producer who were arrested last Friday on suspicion of committing sexual acts with a girl may have other victims.

Melinda Smith, 35, and Jason Whitney, 43, were charged Tuesday with eight counts each of sexually abusing a child under the age of 10. They also face a count of possession while armed with a handgun.

Smith is also known as Mercedes Carrera, a porn star with an extensive number of credits on IMDB. Police initially said Whitney, a producer and director of several pornographic films, was known as Jay Allan, but detectives later said that while he occasionally uses that alias on social media platforms, he is better known in the adult film industry as “Daemon Cins.”

Detectives from the Rancho Cucamonga police department say they were first notified of sexual acts against a girl under the age of 10 on Jan. 31. The girl was sexually abused repeatedly over four months by Smith and Whitney, according to police.
