WILBRAHAM - David P. Gatti, the man fatally shot inside a condominium on May 7, had armed himself with a broken wine glass, and was following the homeowner up the stairs when shot dead, according to local and state police.
Gatti, a star football and lacrosse player at Minnechaug Regional High School a decade ago, was "delusional and incoherent" when he entered the homeowner's unit, according to a prepared statement issued Thursday by Hampden District Attorney William M. Bennett.
Gatti suffered from severe depression and schizophrenia and was under a doctor's care, according to Bennett.
The information released by Bennett follows an investigation by Wilbraham police and state police attached to his office.
The investigation was aided with the cooperation of homeowner Ronald Duval and Gatti's parents, Bennett said.
The incident started about 8:15 p.m. when Duval, owner of Unit C20, heard a loud rattling on the front door of his unit and someone saying "let me in, let me in."
Before answering the door, Duval picked up his .380 handgun from his briefcase, which was by the door and placed it in his waistband.
Duval is properly licensed to possess and carrying a firearm, according to Bennett.
When Duval opened the door, Gatti, who lived nearby in Unit C25, stepped inside. When Duval asked him who he was and what he was doing, he felt threatened by Gatti's delusional and incoherent responses.
As Duval backed into his kitchen, he pulled the gun and pointed it at Gatti, demanding that he stop.
Gatti continued toward Duval, picked up a wine glass from the dishwasher, broke it and threatened Duval with its broken stem.
Duval continue to back away and yelled at Gatti that he would shoot him if he didn't leave. Gatti told him to go ahead and shoot.
Duval moved up the stairs and continued to yell at Gatti to stop.
When Gatti moved up the stairs, Duval shot him in the leg. When Gatti did not stop, Duval shot again, striking Gatti in the chest.
Gatti slumped to the floor and died from the wound to his chest.
Duval's wife, who had been upstairs taking a shower when Gatti entered the home, called 911.
Gatti's parents, Peter and Ann Gatti, arrived as investigators were working at the scene. They cooperated with requests for information and consented to a search of his condominium.
Ballistic evidence showed that two shots were fired from the landing of the stairs between the first and second floors. A broken wine glass was found partly in the sink and partly on the floor of the condominium.
Massachusetts law recognizes that deadly force may be used in self-defense in limited circumstances, according to Bennett.
Generally, the law requires that one resorting to deadly force in a claim of self-defense must avail himself of all reasonable means of retreat or escape before using deadly force, according to Bennett.
However, state law provides that a homeowner who reasonably believes that a person unlawfully in his home is about to inflict great bodily injury or death upon the homeowner or another person lawfully in his home, may resort to deadly force without first retreating.
Bennett said he has determined there is no probable cause to support criminal charges and that the case will be closed.
According to Bennett, there is insufficient evidence to conclude the homeowner did not act in conformity with the law.
Gatti's parents told investigators of his depression and schizophrenia, according to Bennett.
"The illness had deleteriously affected his career and quality of life," Bennett said. "Despite repeated efforts to find the right combinations of medication, his illness had deteriorated recently. While the symptoms of his condition had begun to manifest troubling thoughts, he had not exhibited violent behavior."
Gatti recently moved back to the area after working four years in Manhattan to take a job as an insurance agent at his parent's firm, G.W. Morisi Insurance Agency of Springfield.
Duval could not be immediately reached for comment.
