A pregnant mother and her unborn baby were killed Friday morning in a car crash. Officials said the deaths could have been avoided.

Jason and Billie Kae Taylor were driving with their 15-year-old son, Jacob, and their 11-year-old daughter, Janelle in the back seat along Route 30 in Hanover Township around 9 a.m.

According to police, an oncoming car hit a patch of ice, spun and hit the Taylor’s Pontiac G6 head-on.

Billie Kae and her unborn child were killed in the crash and the other three family members were injured, officials said.

Jason Taylor and his children’s conditions have not been released.

According to authorities, no one in the Taylor’s car was wearing a seat belt. Officials said proper use of the seat belt could have saved two lives.

The driver of the other vehicle, whose name has not been released, wasn’t badly injured, police said.
