MUSKOGEE COUNTY, Oklahoma - The Muskogee County Sheriff’s Office is assisting the Department of Corrections in a search for an escaped inmate.

According to the department’s Facebook page, Markus Perry escaped from the Jess Dunn Correctional Center around 7:50 a.m. Thursday, July 05, 2018. They said he was being escorted from one part of the prison yard to another.

Investigators said he climbed over the fence and into the woods. Corrections officers chased after him but weren't able to catch him.

"We want to hopefully catch this guy. Hopefully, he's still in this area. That's what we're still trying to do, so that is the main goal," said Muskogee County Sheriff Rob Frazier.

The sheriff’s office said Perry was last seen running north from 134th and Old Taft Road and into a wooded area. The D.O.C. has set up a perimeter to contain him to the area.

They said he was wearing a white t-shirt and gray scrub pants. We're told he's about 6-foot-1-inch tall and 180 pounds.

Investigators are also using a K9 and a drone to assist them in the search.

Perry was sentenced to 25 years suspended on a 2014 case. Records show he failed to register as a sex offender and was charged for that. Perry pled guilty and was ordered to serve two years on the sex offender and child sex abuse charge.

Perry is not the first prisoner to escape from the Jess Dunn, according to Sheriff Frazier this is the fourth escaped prisoner this year.

"We catch them and we try to prosecute them but these guys that are escaping have been proven guilty that they have done these heinous crimes," said Frazier.

Anyone that sees Perry is asked to call 911.
