WEST ISLIP - A 16-year-old boy is in a coma after he was struck in a hit-and-run on New Year's Eve in West Islip, and a witness suggests it may not have been an accident.

Witness Brenna Krowl, also 16, says her friend Ryan McCarthy was walking along Udall Road when he was struck at around 10:30 p.m. on Monday. She says McCarthy had been walking along the busy road with another friend when someone in a passing car started yelling at the two boys.

Krowl says the boys yelled back before the driver apparently struck McCarthy and then took off. She says she believes the junior at West Islip High School was deliberately hit.

Krowl says she sprang into action to help save McCarthy. He was rushed to Good Samaritan Hospital, where he remains in critical condition.

Other witnesses have told police that they saw a light blue sports car driving away from the scene. They said the vehicle may have had damage to the driver's side headlight and side-view mirror.

Anyone with information on the crash is being urged to call Crime Stoppers at 1-800-220-TIPS.
