LAKE GROVE - Suffolk County police say they are searching for a suspect who hit a teenager while riding a snowmobile during Sunday's blizzard and then took off.

Police say 14-year-old Ed Depalo, Jr.'s knee shattered when he was struck by a man driving a snowmobile down Browns Road in Lake Grove at around 8 p.m.

Orthopedic surgeon Dr. James Penna says Depalo's knee was nearly destroyed when he arrived at Stony Brook University Medical Center. Penna says the teen has undergone two surgeries so far and has months of painful rehabilitation ahead of him.
