BRENTWOOD - An Epping man was sentenced to 2 ½ to 6 years in state prison after pleading guilty Monday to driving drunk when he struck a young Somersworth girl and her grandfather on their motorcycle.

Thomas Grenier, 48, accepted responsibility for the crash in Fremont on April 17, 2011, but offered no apology to 7-year-old Cloe Adams or her grandfather, Joseph Therrien Sr., of Fremont, during his sentencing in Rockingham County Superior Court.

Grenier pleaded guilty to a charge of aggravated driving while intoxicated resulting in serious bodily injury. In addition to prison time, Grenier’s driver’s license will be suspended for two years after his release and he was fined $1,000 and must pay $5,220 in restitution to Cloe and her grandfather. He was also ordered to undergo drug and alcohol treatment and complete a multiple offender program.

According to police, Grenier was driving his Toyota Scion on Chester Road in Fremont when he hit Therrien’s motorcycle head-on. Cloe was riding on the back of Therrien’s bike and suffered fractured femur, tibia and fibula bones in her left leg which required doctors to insert a metal plate in her femur and two rods in her fibula and tibula. Therrien also suffered a torn rotator cuff and had shoulder surgery in August.

Assistant Rockingham County Attorney Jerome Blanchard said Grenier acknowledged several times that he was at fault after the accident.

Grenier has a lengthy criminal record that includes a DWI conviction in 1991 and others for drug possession and resisting arrest.

Cloe and her family, including her grandfather, attended Monday’s sentencing along with Grenier’s family.

Therrien addressed Grenier, telling him that he appreciated his admission of guilt and honesty. He said he hopes he gets the help he needs and is “clean and sober” when he’s released from prison.

Therrien and other family members said their only wish was for Grenier to lose his license indefinitely.

"Most people who drive drunk just continue and continue," Therrien said after the hearing.
