Authorities say a headless body found in North Carolina last week belonged to a prisoner who escaped from a jail last month.

News outlets report that 26-year-old Kelvin Singleton's partially decomposed body was found April 7 in a remote Bertie County field.

Less than two weeks earlier, and about 10 miles away, authorities say Singleton had formed a weapon from a sharpened toothbrush and forced a deputy at the Chowan County Detention Facility to set him free.

Chowan County Sheriff Dwayne Goodwin says Singleton wasn't killed where the body was found. His body was identified by his fingerprints. His head has not been located.

The State Bureau of Investigation has been called in to investigate.

Singleton was in jail awaiting trial for robbery and kidnapping charges.
