DOVER — An East Wakefield woman who killed her brother in a New Year’s Eve car crash will spend six months in jail after pleading guilty to negligent homicide at Strafford County Superior Court.

Dianne Jenner, 46, was under the influence on Dec. 31, 2017, when she flipped the Mitsubishi Endeavor she was driving north on Route 125 in Milton.

Donald Thomas, 58, of Moultonborough, was not wearing his seatbelt. He was ejected from the vehicle and thrown 20 feet into the snow.

Thomas died at the scene from blunt force trauma.

Jenner told New Hampshire state trooper Nathan Sleight she had been at the Dynasty Restaurant and then her daughter’s house in Rochester. She admitted to having four Mai Tais and two beers before trying to drive home.

This past Monday, Assistant County Attorney Katelyn Henmueller said she wanted Jenner to spend between two to four years in prison, but respected Judge Tina Nadeau’s decision to impose a 12-month sentence in the county jail with six months suspended.

Henmueller said that, since the crash, Jenner has participated in a number of rehabilitative programs and performs community service.

“It was a tough case all around,” Henmueller said. “Her life will never be the same again because her brother was the victim.”

If the case had gone to trial, Henmueller had 18 witnesses lined up, as well as some of Jenner’s blood samples taken at Frisbie Memorial Hospital in Rochester after the crash.

Jenner has lost her license for seven years and will be on probation for five years as part of her plea deal. She must also participate meaningfully in, and complete, any counseling, treatment and educational programs as directed by probation and parole officers.
