GRADY COUNTY, Okla. -- Lawmen in Grady County are in the middle of a manhunt for one of their most wanted criminals.
Authorities have been hot on the trail of Keith Thornburh for weeks.
They almost had him at one point, but he got away, and now they have no idea where he is.
The name Thornburg has been in many News Channel 4 stories over the past year.
While "In Your Corner" reporter Scott Hines continues to deal with one member of the Thornburg family, another relative is the focus of a manhunt.
The Grady County Sheriff said Keith Thornburg is at the top of his most wanted list.
Thornburg is wanted on two felony counts including assault and battery with a dangerous weapon and assault and battery in addition to several other serious accusations.
"Rape, kidnapping, drugs, child porn," Grady County Sheriff Art Kell said.
The problem is, they have no idea where Thornburg is hiding.
"We can't get any location on him right now but we're hoping the viewers of Channel 4 can help us out," Kell said.
Court records said Thornburg "sucker punched" a man he thought snitched him out to police and then threatened him with a "buck knife."
"He hit the guy from behind and took a knife and threatened to stab him, and the reason he did that is he thought this guy was snitching him off," Kell said. "The guy wasn't."
This is not the first time Thornburg has been in trouble for assault with a deadly weapon.
In 2001 he was sentenced to five years in prison for the same thing.
"We want to find this guy before he does commit some type of murder or some heinous crime," Kell said.
Authorities warn anyone Thornburg may be staying with during this time they will be arrested for harboring a fugitive.
