NASHVILLE, Tenn. – A death row inmate, who was convicted of murdering an Oklahoma Air Force sergeant, was found dead in his cell.

Authorities say 54-year-old Michael Wayne Howell was pronounced dead on Dec. 18 at the Lois M. DeBerry Special Needs Facility in Nashville.

Officials say he died of natural causes.

Howell was convicted of first-degree murder and grand larceny for the 1987 murder of Alvin Kennedy, a Memphis convenience store clerk.

He was also convicted of murdering a Tinker Air Force Base sergeant.

Authorities say Howell and Mona Lisa Watson killed 23-year-old Sgt. Charlene Calhoun at random for her car in 1987 during a cross-country crime spree.

Calhoun was shot in the face outside a friend’s Del City apartment.
