A man who admitted to federal charges in an online undercover operation will spend 10 years in prison. 

Josuel  Usana, who pleaded guilty to attempted enticement of a minor, was sentenced in the District Court of Guam. 

As KUAM reported, a special agent went undercover pretending to be a 14-year-old girl on Andersen Air Force Base.

Usana admitted to the feds he knew he was sending sexually explicit messages with teen girls.
