GREAT FALLS — A judge imposed a 110-year prison sentence on a woman convicted of coercing two teenage girls into sex acts before a Web camera, for paying Internet clients.
Tammy Halling, 37, was found guilty of sexual exploitation of children and distribution of child pornography during a one-day trial in February. U.S. District Judge Sam Haddon sentenced her Tuesday.
Halling's daughter, Amber, 20, pleaded guilty to two counts of sexual exploitation of children on Feb. 16. She faces up to 30 years in prison when she is sentenced on June 19.
The U.S. attorney's office said police were alerted to the crimes when a middle school student told her school counselor about the sexual activities.
A search of the Hallings' residence turned up a Web camera and a computer that contained multiple chat logs documenting the shows, court records said. Prosecutors said the Hallings accepted up to $800 from Internet viewers using credit card accounts.
