OSSINING - A prominent Westchester attorney was killed by an alleged drunken driver in Ossining last night.

Police say Michelle Sergio, 38, of Nanuet, struck and killed John Mangialardi, of Briarcliff Manor, with her Nissan at the intersection of routes 9A and 134.

Mangialardi, who was running for Ossining town judge, is believed to have been checking on campaign signs at the time of the accident. The 55-year-old was a partner in the Hartsdale firm of Mangialardi and Berardino and was a major in the New York Guard. He had also served as a lieutenant colonel in the National Guard.

Mangialardi co-hosted 'Anything Goes,' a cable television show featuring discussions of politics, law and current events. He leaves behind a wife and two daughters.
