Leavenworth, Kansas (AP) -- A man will face capital murder charges in the death of his two sons, whose bodies were found in their Leavenworth County home Saturday.

Forty-year-old Donny Ray Jackson Jr. also was charged Tuesday with two alternative counts of first-degree murder.

Investigators allege Jackson killed 14-year-old Logan Jackson and 12-year-old Austin Jackson and the took their younger sisters from the home.

He was stopped and arrested Saturday night in Oklahoma and the girls were found safe.

Leavenworth County Attorney Todd Thompson would not discuss a possible motive, or how the boys were killed.

The Leavenworth County Sheriff’s Department said Jackson and the children’s mother were going through a divorce, and he had “on-again, off-again access to the children.”

Jackson remains in Oklahoma awaiting extradition proceedings.
