A man who allegedly paid the mother of a 14-year-old girl so he could have sex with the child has been charged with sexual assault.

According to the Denver district attorney's office, Mark Mathias, 48, paid the mother money over a 10-month period. Investigators said that from June 18, 2008, through March 31, Mathias repeatedly sexually assaulted the girl.

The child told investigators that her mother would use a cellphone to contact different men, telling them that "fresh meat (was) available."

Detective Kenneth Klaus said in court documents that when the mother's cellphone records were reviewed, "an extensive contact list was revealed."

In addition to the sexual-assault charge, Mathias was charged with soliciting for child prostitution as well as sexual assault - pattern of child abuse.

Prosecutors said the mother was charged earlier with pimping and pandering of a child. Her bail has been set at $200,000.

Mathias is being held on $100,000 bail. He is scheduled to appear in Denver County court Wednesday to be advised of the charges.
