A driver in Pennsylvania fell asleep at the wheel when she crossed into oncoming traffic.

A Northampton County judge on Wednesday sentenced 71-year-old Susan Queen to six months to two years minus a day in county jail for causing the head-on wreck that killed the 22-year-old Alana Hein in Lehigh Township in 2017. She was also sentenced to serve three years probation.

The fatal crash occurred as Queen’s Chevy Equinox was headed north on Route 145 just north of Blue Mountain Drive. Police said Queen’s vehicle crossed over the double-yellow line, colliding with Hein’s southbound Kia Optima.

A review of airbag control data by Pennsylvania State Police reportedly found Queen’s car accelerated slightly from 43 mph to 49 mph during her drive and that she didn’t apply the brakes in the split seconds before the wreck.
