Big reward offered to help catch a fugitive

STILLWATER, Okla. — A dangerous criminal is still on the loose, and authorities are willing to pay to help get him back behind bars.

The U.S. Marshals Service is offering a $5,000 reward for information that leads to the arrest of 34-year-old Patrick M. Walker, who escaped the Payne County Jail on Thursday.

Walker was serving a life sentence for murder before he was able to use his resemblance to another inmate to walk out of prison.

Authorities say Walker, also known as "Notty G," appears to have conspired with someone outside the jail who posted bond for an inmate that Walker impersonated.

The corrections department says Walker may be going by the fellow inmate's name and is believed to have that person's personal identification.
