Jonathan Harris CAPTURED by U.S. Marshals

MILWAUKEE (WITI) -- U.S. Marshals are looking for 29-year-old Jonathan Harris -- a man they call a sexual deviant. He served time, but Marshals say he failed to serve his full sentence.

Harris is accused of violating his parole on multiple occasions and going off electronic monitoring back in January 2013.

"He does not obey the rules. It's something in his makeup. He's required by law to wear the GPS tracking device," Michelle Harings with the U.S. Marshals Fugitive Task Force said.

Investigators accused him of twice sexually assaulting young teens. One charge took place in 2002 and the other in 2003.

Law enforcement says both his victims were only 14. Once he is accused of manipulating through the internet. Officials say a chat room led to an encounter and charges for Harris.

Officials say it is possible Harris could be hiding out on Milwaukee's south side or in the city's central area.

Harris is described as about 6'4" tall, weighing 290 pounds. He has a tattoo with the name "Isabella" on his right arm.

If you've seen him, law enforcement wants to hear from you at (414) 297-3707.
