CONCORD, N.H. — A woman convicted of negligent homicide after a fatal boat crash and later charged with speeding on the road and nearly running down a trooper is back in court – this time for distracted driving.

Erica Blizzard, 42, of Laconia, was ticketed in September for texting while driving, which has been illegal in New Hampshire since July. She is due in court this month.

Blizzard, who was head of the New Hampshire Recreational Boaters Association, was piloting her high-performance boat on Lake Winnipesaukee with two friends aboard after a night of drinking at about 2:30 a.m. on June 15, 2008, when she plowed into a rock ledge on Diamond Island. Stephanie Beaudoin, of Meredith, died in the crash. Another passenger, Nicole Shinopulos, of Burlington, Massachusetts, was injured. Blizzard’s face was shattered, and she required numerous surgeries to repair the damage.

The jury found her guilty of negligent homicide for failing to keep a proper lookout. She was acquitted of an alcohol-related count.

Blizzard said at sentencing that losing her best friend “is something I will have to live with for the rest of my life.”

The day after she was convicted in March 2010, Blizzard was charged with driving 84 mph in a 65 mph zone on Interstate 93 and almost running down the trooper who tried to wave her down as she fumbled with her cellphone. Judge Kathleen McGuire referenced the new charge when she sentenced Blizzard to six months in jail for the boat crash.

“You’ve got to wonder how anyone responsible for an accident because of negligent operation could engage in such conduct,” she said. “You would think that she would be the most cautious person in the world after that. There has to be some disconnect there.”

Blizzard was found guilty of negligent driving in 2011 for the speeding charge and was fined $250. Judicial Branch spokeswoman Carole Alfano said there is no defense lawyer named in Blizzard’s court file. A phone listed in Blizzard’s name was not in service. Messages were left for her Monday at the marina where she works.

State Police Sgt. Pamela Heath, a police prosecutor, said Saturday that the records of Blizzard’s most recent violation are filed with the court and she could not elaborate on the motor vehicle stop.

Two months before the fatal accident, Blizzard testified before the Legislature against imposing speed limits on Lake Winnipesaukee, the state’s largest lake. The Legislature ended up setting speed limits of 30 mph at night and 45 mph during the day.

Blizzard’s trial on the latest charge is set for Jan. 25 in Laconia.
