A former foster mother who was accused last year of sexually assaulting her teenage foster son faces a new charge involving a second foster child.

Phylecia Bien, who was known as Phylecia Humphries when she was arrested on Dec. 20, was booked into the Brown County Jail Thursday on a charge of sexual assault of a child, jail records state.

Bien, 26, of Brownwood, is free on $25,000 bond. She was named in a sealed indictment handed down on May 1, 35th District Court records show.

Authorities arrested Bien in December after learning that a foster child who lived in her home was likely the father of Bien’s daughter. The daughter was born in June 2006, and DNA analysis indicates there is a 99.998 percent likelihood that the boy is the father, a complaint alleges.

Police learned of a second alleged victim — a teenage foster child who was living in Bien’s home when he was allegedly sexually assaulted in 2005, police Sgt. Troy Carroll said.

The boy was 16 when he lived in Bien’s home for about a month, Carroll said.

“Investigations continue to determine if there are other victims,” Carroll said.

After Bien’s December arrest, CPS spokeswoman Marleigh Meisner said that Bien and her husband were no longer foster parents.
