A Medford woman faces more than a decade in federal prison after admitting she exchanged naked photographs of her toddler son in attempts to get child pornography.

Lea Kathryn Jones pleaded guilty to a felony count of transporting child pornography Tuesday in U.S. District Court in Medford, admitting she engaged in Kik Messenger chats with an undercover FBI agent, according to documents filed Tuesday in her case.

Kik is a smartphone messaging app often seen as anonymous because it doesn’t require users to provide an email address or phone number, according to previous child pornography cases that involved the messaging app. Jones reportedly used the handle "hrnymomma" in the exchange.

According to court documents, Jones initiated contact with the undercover agent.

"Hey i found your kik on a website. Im a mom and id love to trade tot pics," Jones wrote before using explicit terms to request photographs of the undercover agent's fictional daughter and submitting naked photos of her son prior to her July 15 arrest last year.

Jones will be sentenced at a later date, but her public defender is seeking a 10-year sentence for the crime, while federal prosecutors are requesting a minimum 15 years in prison.

U.S. marshals arrested Jones July 15 last year after investigators issued a search warrant at her apartment in the 1400 block of Poplar Drive and found more than 10 but fewer than 150 child pornography files, according to court documents. Her Samsung Galaxy Note 4 smartphone was seized along with other digital equipment. In September, Jones was placed on supervised release and ordered not to have any contact with her son.

In addition to photographs of her child, investigators found several other images of child pornography downloaded from the internet.
