A woman who was trying to save a stray dog on a highway in north Alabama died after she was struck by a vehicle during the rescue attempt, police said.

Christina Nicole Green, 31, of Decatur was a passenger in a vehicle traveling on U.S. 431 Saturday night when she saw a dog trying to cross traffic and wanted to help it get out of the road, WAFF-TV reported.

The driver of the vehicle stopped at Green’s request, and she walked across the northbound lane and median before being struck by a pickup truck in the southbound lane, Albertville police said.

Green died at the scene, and the driver of the pickup was not hurt. No charges were filed, and it wasn’t immediately clear what happened to the dog.
