An Arkansas man is behind bars for allegedly stabbing and killing his husband during a camping trip, authorities say.

Gregory S. Whitt Jr., 39, stands accused of one count of murder in the first degree , according to the Crawford County Sheriff's Office.

The defendant appeared in a Crawford County courtroom on Tuesday where he pleaded not guilty to the charge.

Law enforcement, however, says Whitt previously admitted to the brutal murder of Kevin Whitt, formerly Kevin Pennington. The incident occurred last month while the two camped out in the woods near Van Buren, a small city located a few miles east of the Natural State's border with Oklahoma.
