BELFAST, Maine — Thomas Bonfanti, a Northfield man accused of killing three people and severely wounding a fourth in a February 2020 shooting spree, was found guilty Wednesday evening on all counts. Bonfanti, 65, reacted stoically, staring straight ahead while seated at the defense table as the verdict was announced. The jury of eight men and four women deliberated for nearly 2 1/2 hours before finding Bonfanti guilty. He testified earlier Wednesday, telling the jury that he shot two victims by accident.
