WESTON, Mass. (AP) – A 26-year-old nurse pleaded innocent Friday to drunken driving and vehicular homicide charges after she allegedly killed a man in a Thanksgiving morning hit-and-run on the Massachusetts Turnpike.

Police said Jai Aggarwal, 25, a computer engineer and Northeastern University graduate student from Cambridge, had pulled his Mercedes to the side of the highway in Weston to fix his windshield wipers when he was hit around 2:30 a.m. Thursday.

The other driver, Amy Jennings, of Shrewsbury, allegedly continued driving another 500 feet before leaving her car on the side of the Mass. Pike and walking away. Police said Jennings was drinking from an open container of alcohol when she hit Aggarwal.

Police later found her sitting on a doorstep in a nearby neighborhood. She initially told them she’d been carjacked, but later admitted she was behind the wheel when the car hit Aggarwal.

Her attorney, George Murphy, said Jennings lied because she was panicked and had never been arrested. He said she left the scene to find help and that the open container was actually a half-empty bottle of wine she was bringing home from Thanksgiving dinner at her mother’s.

“She’s devastated,” he said after her arraignment at Waltham District Court.

Jennings is also charged with leaving the scene of a fatal accident and negligent operation. She was released after posting $500 bail.

Aggarwal was pronounced dead at Newton-Wellesley Hospital. His 21-year-old passenger, Amjuli Rahdev, of Boston, was not injured.

A high-tech entrepreneur who founded rjsNetworks, a Web hosting and consulting business, at age 18, Aggarwal grew up outside Orlando, Fla. He moved to the Boston area to attend Northeastern’s computer engineering program, but had continued to run the business from Cambridge.
