BRYN MAWR, Pa. (CBS) — A 77-year-old Main Line woman will spend at least three months in the Montgomery County prison for leaving the scene of a hit and run crash, last year, in Bryn Mawr that seriously injured a young teenager riding his bicycle.

Suzanne Lammers pleaded guilty over the summer to a felony charge of leaving the scene of an accident involving serious injury.

Defense attorney Frank DeSimone argued for house arrest, but the judge found no compelling reason for it and sentenced the Villanova woman to three to 23 months behind bars followed by one year probation.

Prosecutor Tom McGoldrick:

“She fled the scene, did not return to the scene, she knew darn well what had happened, that she had hit a boy on a bicycle. There’s no doubt in my mind about that, and instead of facing the consequences, she was worried about herself and she drove home.”

It wasn’t until two weeks later when police received a tip that they found the car in the woman’s garage. The teen suffered serious head and leg injuries and hearing loss, but continues to recover. Lammers became physically ill in the courtroom after hearing the sentence.
