WEST ISLIP - A week after a 16-year-old boy was struck by a driver and left for dead on a West Islip street, Suffolk County police say they have made a break in the investigation.

Authorities say the vehicle that struck Ryan McCarthy on New Year's Eve has been impounded. It's a Chrysler 300 that has damage to the driver's side headlight and side-view mirror.

As News 12 Long Island has reported, McCarthy had exchanged words with the driver of a car of that make and model as he walked along Udall Road on the night of Dec. 31. Witnesses say the driver of the car then turned around and deliberately hit McCarthy.

The force of the impact put the teen into a coma with head injuries, although his current condition is unknown.

On Friday, police released a picture of the Chrysler that they said had hit McCarthy. The vehicle in the photo provided by police was blue in color, and the car that was impounded today was much darker.

Police say no arrests have been made in the case, and how investigators tracked down the vehicle remains unclear.
