The Tri-City Record has learned that a Farmington man accused of second-degree murder entered a a plea deal and was sentenced back in February.

Serrono Rippingale, 28, was charged in the May 3, 2025, killing of Alissa Greenfield, who was found by dead by Farmington police at a home in the 1200 block of Randolph Avenue, where Rippingale lived.

The man admitted to the killing on Jan. 13, telling the court that he got into an argument with Greenfield on the day of her death and “strangled her,” according to the audio log notes.

A witness had told police that she saw Rippingale “wrestling” with Greenfield and saw the woman with blue lips and “foaming at the mouth” before she died, court records state.

Rippingale was sentenced Feb. 17 after a 40-minute hearing in front of District Court Judge Curtis Gurley.

During the sentencing Rippingale asked for forgiveness. “Please forgive me. I know I don’t’ deserve it … I’m sorry for your untimely loss,” he said.

His defense attorney Gregory Gaudette asked for leniency, saying alcohol was an issue for his client.

Gurley said the plea agreement put him “in a hard spot,” and that “the violence in this spreads in the community like a cancer,” in which many are affected.

“Like cancer, grief cannot be cured,” Gurley said before sentencing Rippingale to 18 years in the Department of Corrections.

Per the conditions of the plea agreement, the judge suspended all but 12 years and ordered that upon release Rippingale be placed on five years of probation, two of which would be parole.

Gurley also ordered it be considered a serious violent offense.
