Suffolk police are investigating a fatal hit-and-run accident that left one man dead early Saturday morning.

Authorities responded to a call at around 4:30 a.m. about a body found on the side of Jericho Turnpike near Caleb Smith State Park. The victim was identified as Mark Telfer, 58, of Stony Brook.

At around 11:30 a.m., police arrested Kim Sandvoss, of Shirley, who is accused of running down Telfer and leaving him for dead on the road.

The stretch of Jericho Turnpike that passes through Smithtown has become notorious for accidents. In October 2007, three teenagers were killed in a crash in the area. Several months prior to that, a 63-year-old woman died in an accident.

In the aftermath of the 2007 accidents, state authorities reduced the westbound side from two lanes to one and made the second lane into a turning lane and a median. They have also reduced the speed limit on Jericho Turnpike.

?I was pleased with the new changes they made to the lanes,? says Frank Ambrosino, of Smithtown. ?It's definitely made it easier for us to pull out.?

Sandvoss was charged with leaving the scene of an accident. She is scheduled to be arraigned Sunday.
