Driving drunk on the way to work, Michelle Sergio hit and killed John Mangialardi, who was putting campaign signs up on Route 9A on Sept. 3, 2013. 

John Mangialardi, an attorney, Briarcliff Manor resident, and Lieutenant Colonel in the 56th Brigade, N.Y. Guard, was running for Ossining town justice. He was 55. 

Today Westchester County Attorney Janet DiFiore announced that Sergio, 39, of 53 Eagle Ridge Way, Nanuet, pled guilty to the entire indictment that charged her with:

• two counts of Vehicular Manslaughter in the Second Degree, class “D” Felonies
• two counts of Driving While Intoxicated, class “A” Misdemeanors

According to the DA, at 10:15 pm, at the intersection of Route 9A and Route 134, in the Town of Ossining, the defendant, on the way to work at a social service agency in Ossining, struck the victim as he was crossing Route 9A.

The victim was pronounced dead at the scene shortly thereafter by responding EMTs.

Sergio was found to have a blood alcohol level of .12 at the time of this incident. Police initiated an accident reconstruction and the defendant was subsequently arrested.
 
Sentencing will be on Aug. 11. She faces a maximum sentence of seven years in state prison.
 
Assistant District Attorney Timothy Ward, Chief of the Career Criminal Bureau, is prosecuting the case.

At the cost of a life this woman will receive a new life. Let her live a sober one for all people who cross her path. RIP John the legal system will take it from here.

Sad...no winners..a poor mans life was snuffed out...and this woman's life? Agree with you Cathy.

The idea that the accident was avoidable had she had a lower blood alcohol level is speculation of the worst sort. I hope that she has a rational judge - a long shot in today's courts - with mercy. Accident reconstruction is but a lick better than dowsing.

Can someone tell me how he got in front of her car.Tell me how you would have ended up dead under the same circumstances. What would cause you to be in front of her car on a highway and whose fault would it be. this is a 4 lane highway with 45 mph speed limit, she had her lights on or we would have heard about it or she would have been caught long before this happened. She did not swerve into him because he was killed in the road not on the side of the road. So, does it matter at all how he got in front of her car or just that she was .04 over the limit and on her way to work. I have my theory but it is long and there are no victims,well maybe 1.I will post it if asked by 2 people. In a nutshell, the death was an accident on her part and careless on his. In reality she is guilty of DWI not manslaughter. Under the law she is screwed. my conclusion is based on circumstances related to this case and and this case only
