GENESEO (AP) - A truck driver pleaded not guilty Wednesday to perjury and other charges in a hit-and-run accident on an interstate highway that killed a college student from Long Island.

Investigators tracked down three drivers whose vehicles struck Kaitlin Ann Charity, 20, as she walked back to her car soon after being pulled over for speeding on Interstate 390 in rural Western New York.

One of them, trucker John Martarello, 49, was arraigned on two felony charges of first-degree perjury and leaving an accident scene without reporting. If convicted, he could be sentenced to a maximum of 28 months to seven years in prison on each charge.

The other two drivers will not be charged, Livingston County prosecutor Tom Moran said.

Calls to defense attorney Fred Neroni's office were not immediately returned.

Charity, of Islip, was pulled over for speeding an hour before dawn on Oct. 20 near the end of her drive back to school at the State University of New York in Geneseo.

She got out of her car when the trooper drove off to pursue another speeding vehicle and walked to the side of the highway, then was hit as she returned to her car, police said.

The accident happened some 35 miles south of Rochester and police have said it was possible the drivers, who did not stop, didn't realize a pedestrian had been struck.
