On the evening of April 15, 1948, then aged 15, Nassar and two friends, 16-year-olds Gennaro Pullino and William Kenney, committed a series of robberies in their hometown of Lawrence. They stole $80 () from three local businesses, but failed to rob fourth, a
convenience store, when owner Victoria Borisek drove the robbers out with a broom after being threatened at gunpoint. The fifth and final business the trio robbed was a variety store on 99 Park Street, run by 59-year-old
Lithuanian-born shop owner Dominic Kirmil. After the robbers distracted the owner by ordering soda, Nassar pulled out a
revolver from his trench coat and told Kirmil. "Throw the cokes out; this is a stick-up". In response, Kirmil threw the bottle of
Coca-Cola he held in his hand at the face of one of the assailants, with Nassar retaliating by shooting Kirmil four times in the chest, arm, and hand. Nassar and his accomplices fled the store, after which Kirmil was found by two children passing by the scene. On May 20, Nassar was picked up by Lawrence patrolmen Charles Keenan and Walter Sliva after crashing a stolen car on
Route 110 in
Ayer, Massachusetts. Initially charged with
auto theft, Nassar soon became a prominent suspect in the Kirmil murder. The police found two
.38 caliber bullets in his pocket, and the nickel-plated
revolver used in the murder in the wrecked car. Nassar confessed to the shooting and gave his motive as "for excitement". Nassar and his friends Pullino and Kenney were indicted and initially charged with
first degree murder, which carried a mandatory death sentence under Massachusetts law at the time. However, on account of the youth of the defendants, the charge was downgraded to a
second degree murder, to which they pled guilty. On January 17, 1949, all three were formally sentenced to
life in prison.
Imprisonment and release Nassar was sent to the prison
Massachusetts Correctional Institution – Norfolk in
Dedham, Massachusetts. During his incarceration, Nassar gained an interest in studying the
Russian language and formed a friendship with
Unitarian minister William Moors and joined the Prison's Debating Society. Through the efforts of Moors, Nassar was
paroled early in 1961, with Nassar claiming that he sought to attend
Northeastern University to major in Russian. His parole was criticized by several Massachusetts political figures. Middlesex and Suffolk district state senator Francis X. McCann made a statement demanding the parole board disclose the reasons for Nassar's release while Massachusetts state representative Perlie Dyar Chase opined that the Massachusetts State Crime Commission should re-examine all paroles and pardons handed out by the state in the last decade. According to Ames Robey, medical director of
Bridgewater State Hospital, Nassar became involved in the
Irish Gang War in
Charlestown, Boston, and was connected to at least 17 murders and possibly a total of 30. Robey would later also voice strong suspicions that Nassar could have committed the Boston Strangler killings, as he was released a year before the murders began. ==Murder of Irvin Hilton==
