A Louisiana woman was found dead in her home Thursday, and her two young daughters were abducted and found hours later in Mississippi — one dead and the other alive, police said.

A Louisiana resident who had dated the woman was arrested in Jackson, Mississippi, in connection with the deaths and abduction, investigators said.

“He had the victim’s car along with her alive-and-well 6-year-old child,” said Chief Deputy Jimmy Travis of the Tangipahoa Parish Sheriff Office in Louisiana.

The body of the other child, a 4-year-old, was found near the car in a wooded area in Jackson, Travis said.
