LEAVENWORTH, Kan. (KSNW) – A Leavenworth man is in custody after allegedly killing his two sons and abducting his two young daughters.

Sheriff’s investigators say Donny Jackson killed his two sons, 14-year-old Logan Jackson and 12-year-old Austin Jackson, on Saturday.

“I believe there was a family event, a soccer game, that one of the children was supposed to be at and didn’t show up,” Leavenworth County Undersheriff James Shirley told reporters Saturday evening. “A family member had shown up then and had discovered the crime here at the scene.”

Authorities said Jackson then left his home and took his two daughters, 3-year-old Aven Jackson and 7-year-old Nora Jackson, which prompted a multi-state Amber Alert.

Jackson and the girls were located Saturday night in Oklahoma. Charges have yet to be filed against Jackson.
