A former Endicott College student pleaded guilty to a series of random attacks on campus earlier this year.
Dillon Destefano, 20, a former sophomore student, pleaded guilty to two counts of assault and battery causing serious bodily injury, assault and battery and witness intimidation, according to the Essex district attorney's office.
A judge sentenced Destefano to four years in jail.
Authorities said Destefano was walking on the campus with two friends in February and had been drinking. During the walk, Destefano randomly and without provocation and warning, punched three classmates in the face, authorities said. He also told a witness not to tell anyone what he saw.
One of the victims suffered a shattered jaw and had his mouth wired shut for weeks. Another victim had their orbital bones and sinus cavity shattered and a third victim suffered a swollen lip.
"These were unprovoked random attacks on unsuspecting victims and will never be tolerated," Essex District Attorney Jonathan Blodgett said in a statement.
