Patrick M. Walker duped authorities  at an Oklahoma jail last Thursday by posing as his cellmate — a man he “closely resembles.”
An enormous manhunt is now underway for Walker, who allegedly took his cellmate’s identification card after threatening the lives of the man’s family if he didn’t cooperate.
“He impersonated one of his cellmates, had their identification information like their ID cards, things like that,” said a spokesman for the Oklahoma Department of Correction, Matthew Elliot, as several outlets reported.
“He was able to pose as that inmate and bond out.”
Walker was being held at a jail in Stillwater, Oklahoma, awaiting a court hearing on charges that he assaulted a prison guard at Cimarron Correctional Facility, according to officials.

The felon had served some 15 years of a life sentence for the 2001 murder of 19-year-old Brandon Harian, whom he was convicted of shooting to death in Oklahoma City.
Walker is said to have come up with the escape plan while being transferred to Stillwater.
With the stolen identification information now in his possession, he had someone post bail for the cellmate — and was able to simply walk out after being behind bars since his conviction in 2003.
Documents show that when the staff called for his cellmate upon the arrival of a bondsperson, Walker, 34, responded instead.
Walker cheekily signed his own name on the bail forms before he was released.
The bondsman didn’t catch until it was too late.
Now, state troopers, U.S. marshals, and county deputies are combining forces in their statewide search for the escaped criminal.
Also known as “Notty Walker,” the man is described as dangerous and possibly armed.
“This is a violent individual and he should not be approached or dealt with in any way other than by law enforcement,” said Elliot of the Oklahoma corrections department.
Authorities say Walker may still be using the identity of his former cellmate. The fugitive is 5 feet 7 inches tall, weighs around 175 pounds, and has a long scar on the left side of his face.
“If anybody sees him or thinks they may recognize him, they need to call 911 immediately.”
