A 40-year-old Hooper woman was charged Monday with allegedly raping and having oral sex with her 14-year-old foster son several times in October.

According to charging documents filed in 2nd District Court in Ogden, Jennifer Ann Montag told investigators that she and the boy had intercourse and oral sex several times at her home between Oct. 10 and 26.

Montag is charged with two counts of first-degree felony rape and three counts of first-degree felony forcible sodomy after someone reported the alleged abuse Oct. 28.

Weber County deputies interviewed the boy at the Ogden Children's Justice Center. He said he didn't want to get his foster mother in trouble but acknowledged she had asked him not to "disclose information which could ruin the family or put Montag in jail," court documents state.

At the same time, detectives interviewed Montag, who confessed to some allegations, court documents state. When police later told her one of the boy's siblings told a Department of Child and Family Services caseworker that the teen admitted to having sexual encounters with Montag, she confessed to more allegations, court documents state.

Liz Sollis, spokeswoman for the Utah Department of Human Services, said all foster children have been removed from Montag's home.

"We act immediately in getting them to a safe place," Sollis said.

Montag passed background screenings in 2007, 2008 and 2009. The check includes national criminal databases, as well as child abuse and elder abuse databases.
