A drunk driver who killed a candidate running for Ossining town justice last September while he was crossing Route 9A to put up campaign signs pled guilty last week to vehicular manslaughter and driving while intoxicated.
Michelle Sergio, 39, of Nanuet, who was on her way to work at a social service agency in Ossining when she struck and killed John Mangialardi, 55, of Briarcliff Manor, September 3, 2013 at about 10:15 p.m., could face seven years in state prison when she is sentenced on August 11.
Mangialardi, a well-known defense lawyer, was pronounced dead at the scene. He was a former Assistant D.A. in the Bronx and was a partner in the law firm of Mangialardi & Berardino in Hartsdale. He was a Lt. Colonel in the 5th Legal Support Detachment, 56th Brigade, N.Y. Guard and had been a JAG Officer for more than 14 years. He was an active parishioner of St. Augustine Church.
At the time of the crash, Sergio was charged with misdemeanor driving while intoxicated by Westchester County Police after having a blood alcohol level of .12.. She was later charged with vehicular manslaughter, a felony.
According to published reports, Sergio and another motorist passing by said they did not see Mangialardi. The roadway was shut down for nine hours during a police investigation and Sergio was subsequently arrested.
Mangialardi is survived by his wife, Arlene (Paregian); daughters Katie and Linlee; parents Dominic and Nancy; and other close relatives.
