(KTIV) - A Winnebago, Nebraska, man is being charged with manslaughter in the death of his girlfriend.
According to a news release from the U.S. Department of Justice, 20-year-old Jonathan Rooney is being charged with Manslaughter occurring in Indian Country for the death of Kozee Decorah.
Rooney was arrested on June 1. He appeared before U.S. Magistrate Judge Susan Bazis on Wednesday.
A preliminary hearing and detention hearing will be held at a later date.
According to a criminal complaint filed May 29 in U.S. District Court, shortly before 8 p.m. on May 16, Winnebago Police received a call from Decorah who said the vehicle she was traveling in with Rooney and her four-month-old infant son got stuck in a muddy road in a remote area of the Winnebago Indian Reservation.
Two officers were unable to find the three but located the vehicle in the area known as Honey Creek Road. Later that night firefighters helped in the search when the group noticed a fire in an outhouse by a cabin.
Inside the cabin, the group found Rooney and the child but not Decorah.
While in the cabin, the complaint says officers noticed human remains in a burned outhouse.
Rooney faces up to 15 years in federal prison if he's convicted.
The case was investigated by the Winnebago Police Department, the Nebraska State Fire Marshal, and the Federal Bureau of Investigation.
