MILFORD – A Hillsborough County grand jury has indicted a Winchester woman on a charge of negligent homicide in a 2016 Milford crash that killed a woman from Belmont.

Roberta Odell, now 54, was driving east on Route 101 on May 3, 2016, when her 2011 Nissan Rogue went into the westbound lane and collided with a 2007 Kia Spectra, according to police reports.

Susan Robbs, 69, of Belmont, the retired owner of a Gilford preschool-daycare, was pronounced dead at the scene. She was a front-seat passenger in the car driven by her husband, Thomas Robbs, 74, of Belmont.

According to the indictment, Odell was “passing cars in a no-passing zone at unreasonable speeds and failing to leave sufficient room to pass a tractor trailer, resulting in her colliding into an oncoming car.”

Police said Odell was heading east in the passing zone and attempted to pass another vehicle and went into the westbound lanes and hit the westbound Kia head-on.

The Nissan wound up half over the Route 13 overpass guardrail, and Odell was airlifted to Dartmouth Hitchcock Medical Center in Lebanon, where she had been listed in serious condition. Thomas Robbs was taken to the hospital with non-life threatening injuries.

Negligent homicide is a Class B felony punishable by 3 1/2 to 7 years in prison.
