CROSSLAKE  (AP) - Police say a Crosslake woman has died after she tried to stop a rolling pickup truck that her 2-year-old nephew was in.

Police Chief Bob Hartman says the 32-year-old was killed Thursday. The toddler wasn't hurt.

Hartman says the boy was playing inside the pickup when the truck began rolling backward down a hill. He says the woman jumped on the truck's running board and was reaching inside to put it in park when the vehicle sideswiped a large tree.

The woman got caught between the truck and the tree. A witness and emergency responders performed CPR but the woman was pronounced dead at the scene.

Hartman says she apparently died of head trauma.

Her name has not been released.
