RIVERSIDE, Calif. -

A Riverside County nurse caught trying to send child pornography to a girl via the internet was sentenced today to 10 years in federal prison. 

David Christopher Jelaca, 38, of La Quinta pleaded guilty in march to attempted distribution of child pornography to a minor.  U.S. district Judge Virginia Phillips imposed the sentence called for under the plea agreement. 

Jelaca, a registered nurse, was originally charged with four felony counts connected to a federal investigation targeting child porn traders in 2011.  Seven other inland Empire men were snared in the same sting.  Their cases have either been resolved or are awaiting trial. 

According to the U.S. Attorney's office, Jelaca came to the attention of federal investigators when he posted an advertisement on Craigslist seeing to make contact with a "Dirty Daddy who likes to share his daughter's dirty panties."

Multiple law enforcement agencies came together and began communicating with Jelaca via email, posing as respondents to his ad.  Jeleca acknowledged having had sexual intercourse with girls as young as 15 and fantasizing about sexual relations with girls as young as 12.

Agents searched the defendant's home, seizing more than 26,000 still images and 55 movie files containing child porn.
