Tennessee inmates removed speaker from wall, crawled in to escape: Sheriff
WATCH: One of the escapees is a homicide suspect and is now on Tennessee's 10 most wanted list.

Three inmates -- include a homicide suspect -- broke out of a Tennessee county jail today by removing a speaker from the wall, authorities said. They then crawled into the wall and used blankets to lower themselves into a maintenance room, where they kicked the door open to escape, the Macon County Sheriff told ABC News.

A manhunt is underway for the men, identified as Dylan Cecil Ferguson, Jeffrey Strong and Matt White, the Tennessee Bureau of Investigation said. The facility they apparently escaped from -- the Macon County Jail -- is about 60 miles northeast of Nashville.

Ferguson, 20, who faces charges including criminal homicide for a man's death last year, should be considered armed and dangerous, the TBI said.

Dylan Ferguson is seen in this undated photo released by The Tennessee Bureau of Investigation.

"All three subjects may be traveling in a stolen, white, 1990 Ford F-250 with Tennessee tag 3B5-7V2," the TBI said.

Ferguson has been added to the TBI's "Top 10 Most Wanted" list.

He is described by the TBI as a white man with brown hair and green eyes who stands at 6 feet 2 inches tall and weighs about 150 pounds.

Ferguson was one of two people arrested in August 2016 in connection with the death of Brandon Michael Fye, whose remains were found in a wooded area in Macon County, the TBI said at the time.

Ferguson has not entered a plea. He is next scheduled to appear in court on Feb. 5. A public defender who represents him declined to comment.

Anyone with information about Ferguson's whereabouts is urged to call the TBI at 1-800-TBI-FIND. A reward of up to $2,500 is available for information that leads to his arrest.
