Thomas Bonfanti of Northfield traveled to three homes and shot and killed three people in February 2020 in the Down East part of the state, prosecutors said.

A fourth shooting victim, Regina Long, survived the attack and spoke during Friday’s sentencing, the Bangor Daily News reported.

The killings took the lives of Sam Powers, Jennifer Bryant-Flynn and Shawn Currey. Prosecutors said Bonfanti drove methodically to their homes and shot them with a handgun.

Bonfanti’s motive for the killings remained unclear.

A jury convicted Bonfanti in June after rejecting his claims that the shootings were accidents and acts of self defense.

The trial was moved Waldo County Superior Court because of concerns about pretrial publicity in Washington County, where the killings took place.
