Call 911 if you see this man

EUGENE, Ore. - A sex offender with a history of abusing girls may be using online dating sites to form relationships with women with young children, probation officials warned.

If you see David Frank Carr, Lane County Parole and Probation asks you to call 911 immediately.

Carr, 41, is wanted on an outstanding warrant for absconding from parole.

He is 5-foot-10, 180 pounds with borwn hair and blue eyes.

Parole officials are concerned that Carr may reoffend. In the past, Carr has deliberately placed himself in contact with children by engaging in relationships with women who have children under the age of 16 and by going to places where children congregate, officials said.

"We would like to warn women who have minor children and use internet dating sites to be cautious about who they are communicating with," said Kim Menjou, Lane County Parole and Probation Supervisor.

Carr was convicted of sexually abusing a 6-year-old girl known to him. He has admitted to abusing several more girls under the age of 15, officials said.
