A man sentenced to life in prison for killing his niece and nephew on the Spirit Lake Indian Reservation is appealing the case to the 8th U.S. Circuit Court of Appeals.
A jury in September found 22-year-old Valentino "Tino" Bagola guilty of two counts of felony murder for the May 2011 slayings of 9-year-old Destiny Jane Shaw-Dubois and her 6-year-old brother, Travis Lee DuBois Jr.
Bagola was sentenced in December to life without the possibility of parole.
Authorities say Bagola stabbed the children to death after he sexually assaulted the girl because he was angry at their father but couldn't find him.
Defense attorneys argued that children's father was responsible. Travis Dubois Sr. originally confessed to the crimes and later recanted.
Bagola's earlier appeals to federal district court were rejected.
