Three siblings – ages 9, 15, and 17, were killed in a crash Monday morning in western Jefferson County.

The crash happened about 8 a.m. on Alabama 269 at Short Creek Road. The two-vehicle wreck involved a car and an 18-wheeler.

Jefferson County sheriff’s Chief Deputy Randy Christian said there were four siblings in the car. The 9-year-old boy was pronounced dead on the scene.

Two sisters, ages 15 and 17, were pronounced dead at area hospitals. The 19-year-old driver remains hospitalized.

The driver of the truck wasn’t injured.

Christian said information on the scene is that both vehicles were traveling along Alabama 269 in opposite directions. The car turned across the highway into the path of the 18-wheeler and the two collided.

The crash remains under investigation.

“This accident obviously has devastated a family,” Christian said. “It will be heart-wrenching for the family, friends and everyone in the community. Our hearts are with them. God wrap your loving arms around this family as they deal with this unimaginable heartbreak.”
