FORT RILEY — A 19-year-old man pleaded guilty to fatally shooting a teenager at Fort Riley while recklessly handling a firearm.

U.S. Attorney Tom Beall says Juwuan Jackson pleaded guilty to involuntary manslaughter in the September 2015 death of 16-year-old Kenyon Givens Jr.

He originally said a masked man broke into the home and shot Givens. He later admitted he was spinning the chamber of a .22-caliber handgun while holding the trigger, causing it to go off.

Beall says the initial false story prevented paramedics from treating Givens until after police searched the house.

Jackson faces up to eight years in federal prison when he is sentenced in January.
