PHILADELPHIA — A Philadelphia woman who prosecutors say offered her 6-year-old daughter for sex on Internet chat rooms is going to prison for 25 years.

Christine Yoder was sentenced Tuesday for producing child pornography and distributing sexually explicit photos.

Prosecutors say the 33-year-old sexually abused two of her daughters, who were 6 and 16-months-old at the time, and photographed the abuse last year.

They say she offered to fly the oldest girl to Detroit to have sex with a man she met online. The man in the chat room was a source who cooperated with FBI agents.

Yoder apologized in court.
