State police responded to the Elm Street address after receiving a call from Leominster police about 3:50 a.m. reporting a man was barricaded inside his apartment. State police were told the man was possibly armed and had suicidal intentions.
The state police Special Tactical Operations Team arrived at 175 Elm St. along with members of the Leominster barracks, crisis negotiators and local police.
Shortly after 7 a.m., state police entered the apartment and found Mr. Desrosiers inside, dead from what authorities described as a self-inflicted gunshot wound. State police decided to enter the apartment after a witness told them she had heard a gunshot earlier in the morning.
