A Sharon mother has died after police said she was run over by a runaway vehicle with her three young children inside. 

Police responded to the call around 9:15 p.m. Tuesday near the intersection of Lorain Street and Logan Avenue.

A witness told them that they saw the vehicle rolling backward down a steep driveway and 31-year-old Kayla Rushwin appeared to be running alongside it to stop it, according to police. 

Police said as the vehicle gained speed, Rushwin tripped and the vehicle rolled over her. 

Rushwin was taken to the hospital where she later died of her injuries. 

Police are not releasing any more information at this point. 

The incident is under investigation.
