FARGO, N.D. (AP) — A man accused of killing two children on the Spirit Lake Reservation says in videotaped interviews that he did it because he was mad at their father and their father wasn't home when he sneaked into the house.

Twenty-year-old Valentino Bagola is on trial in Fargo in the 2011 slayings in St. Michael of 9-year-old Destiny Shaw-Dubois and her 6-year-old brother, Travis Dubois Jr. Authorities say Bagola killed them after sexually assaulting the girl.

Bagola said in police interviews played for the jury Thursday that he knew he was in "some serious trouble" and that he was "sorry for everything I did to those kids."

Bagola's attorneys say his statements were coerced. They also say the children's father confessed to the crime.

Bagola's trial could last three weeks.
