Luigi Mangione's lawyers call on judge to block the death penalty

Lawyers for Luigi Mangione have called on a judge to block federal prosecutors from seeking the death penalty against him.

Mangione's legal team says the 27-year-old's case has been turned into a "Marvel movie" after a failed bid by the US Justice Department to indict him on terrorism charges over the fatal shooting of UnitedHealthcare chief executive Brian Thompson in New York on 4 December. New York state judge Gregory Carro said there was no evidence that the killing, which took place as Mr Thompson walked into an investor conference at the New York Hilton Midtown hotel, amounted to a terrorist act.

But Judge Carro upheld second-degree murder charges, which suggest there was malicious intent - but not that it was premeditated. US Attorney General Pam Bondi has called for Mangione to face capital punishment, describing the charges against him as a "premeditated cold-blooded assassination that shocked America".

But in the new court filing, Mangione's legal team argues federal prosecutors have "violated Mr Mangione's constitutional and statutory rights" by "staging a dehumanizing, unconstitutional 'perp walk' where he was televised, videotaped, and photographed clambering out of a helicopter in shackles" on the way to his first court appearance. The legal team, led by former Manhattan prosecutor Karen Friedman Agnifilo, also claims the death penalty case has been "fatally prejudiced" after President Donald Trump commented on it on Fox News.

Despite laws that prohibit any pre-trial commentary that could prejudice the defendant's right to a free trial, he told the network on Thursday: "Think about Mangione. He shot someone in the back, as clear as you're looking at me or I'm looking at you."

"However, there has never been a situation remotely like this one where prejudice has been so great against a death-eligible defendant." Federal prosecutors have until 31 October to respond to the documents. Mangione has pleaded not guilty to all the state charges against him, which cannot result in the death penalty and only life imprisonment, unlike federal ones.

He has also pleaded guilty to the federal charges. He is due back in court for a pre-trial hearing in the state case on 1 December and the federal case on 5 December.

The 27-year-old was arrested five days after Mr Thompson was killed - when he was spotted at a McDonald's in Altoona, Pennsylvania, around 230 miles west of New York City..
