A Philadelphia mom will serve 25 years for offering her young daughters for sexual abuse online.

Christine Yoder, 33, was sentenced for sexual abuse exploitation charges related to her 6-year-old daughter and a 16-month-old infant. 

She pleaded guilty in March and admitted in court to sending a sexually explicit photograph of her six-year-old daughter to an undercover FBI agent she met on the Internet.

Yoder also agreed to fly her daughter to Detroit for sexual activity. Using the instant messaging app Kik in May 2014 she told the agent “I don’t want anything to do with her after you take her,” according to court documents.

Using usernames like "freakygirl82" and "sexygirl32" on Kik, she sent the messages and told the FBI agent she wanted him to impregnate the six-year-old, court records say.

Federal prosecutors say Yoder produced explicit photographs of her 16-month old daughter.

She pleaded guilty to two counts of producing child pornography and two counts of distributing child pornography. A sentencing hearing is set for June 10. She faces a mandatory minimum sentence of 15 years, with the maximum possibility of a life sentence.
