The defence team for alleged murderer Alessandro Mangione has formally declined to pursue a psychiatric defence in the forthcoming state murder trial, a decision that has prompted scrutiny from British legal professionals. The move, confirmed in a court filing on Monday, signals a tactical shift that could significantly alter the trajectory of the proceedings.
Mangione, 34, faces charges of first-degree murder in connection with the death of Francesca Bellini, 29, a university lecturer found dead in her Manhattan apartment in March 2023. Prosecutors allege that Mangione, a former colleague of Bellini, bludgeoned her with a blunt object following a dispute over academic research. He has pleaded not guilty.
Legal analysts in the United Kingdom, accustomed to the more frequent use of diminished responsibility pleas in English law, have questioned the rationale behind the decision. Professor Michael Haworth, a criminal law specialist at the London School of Economics, described the choice as “high risk”. He noted that without a psychiatric defence, the prosecution’s case, which includes forensic evidence linking Mangione to the crime scene, becomes harder to rebut.
“In the American system, a psychiatric defence often carries a heavy burden, but it can mitigate culpability if successful,” Professor Haworth said. “To forgo it entirely suggests either a lack of credible expert testimony or a belief that the jury will be unsympathetic. Both are substantial gambles.”
Court records indicate that Mangione’s legal team, led by seasoned attorney Carla Reeves, has instead opted to challenge the reliability of the physical evidence and the credibility of a key witness, a neighbour who reported seeing Mangione leaving Bellini’s apartment on the night of the murder. Reeves declined to comment on the record, but a source close to the defence said the team was confident that the state’s case had “significant holes”.
UK barrister Sarah Fielding, who has observed several high-profile American trials, warned that rejecting a psychiatric defence could leave the defendant without a fallback position if the evidentiary challenges fail. “American juries can be unforgiving in cases of violent death,” she said. “The absence of any explanation rooted in mental impairment may harden their view.”
The trial is scheduled to begin in the New York State Supreme Court on 14 October. Legal observers expect jury selection to be protracted, given the media attention the case has attracted. Mangione has been held without bail since his arrest.
Prosecutors have stated that they will seek a life sentence without the possibility of parole. The district attorney’s office has not commented on the defence’s latest filing.
The Mangione case has reignited debate in both the United States and the United Kingdom about the role of psychiatric evidence in murder trials. While English law permits a partial defence of diminished responsibility, reducing a conviction from murder to manslaughter, the United States varies by state. New York requires a defendant to prove that a mental disease or defect deprived them of the capacity to understand the nature of their actions. The threshold is high.
“What we are seeing is a litigation strategy that prioritises control over the narrative,” said Dr Alice Chen, a legal psychologist at Oxford. “By rejecting psychiatry, the defence keeps the focus on procedural errors and reasonable doubt. It is a pure adversarial tactic.”
The trial is expected to last six weeks.
