Luigi Mangione, the man accused of killing United HealthCare CEO Brian Thompson in cold blood late last year, faced a New York state judge Friday for the first time since his December arraignment.

Dressed in a forest green sweater and bulletproof vest, Mangione was led into the courtroom in shackles by security personnel for the status hearing.

His lawyer, Karen Agnifilo, requested permission from Judge Gregory Carro to undo the chains around his arms and legs, but the judge said the security team preferred him in cuffs, according to the BBC.

The 26-year-old was charged with 11 counts, including murder as an act of terrorism, in connection with the CEO slaying Dec. 4, during the health care giant’s annual conference. The public response among Americans, ranging from tacit approval to celebration, alarmed others who viewed the case as a straightforward homicide.

The brief hearing Friday attracted not only members of the press but dozens of supporters, including many women, some of whom also wore green like Mangione. Agnifilo’s arrival to the courtroom was reportedly greeted by applause that was quickly silenced by security officers.

Agnifilo argued that her team needed more time to access and review evidence in the case, including police body camera footage, surveillance footage, data from a cellphone found near the scene and forensic testing information, CNN reported. She said that Mangione’s lockup in a Brooklyn federal prison has made it more difficult for her team to speak to him in person.

Carro set deadlines for motions in the case but did not schedule a date for trial.

Security footage from Dec. 4 showed a masked figure calmly approach Thompson from behind in the early morning light on a street outside a midtown Hilton, firing several shots into Thompson’s back before fleeing. Investigators allege that Mangione fled the city through Central Park before being recognized at a Pennsylvania McDonald’s five days later, when he was brought into custody.

Mangione allegedly was found carrying multiple pieces of fake identification, a statement about the murder and a ghost gun, which is a type of DIY weapon that cannot be traced back to an owner.

Local authorities in Pennsylvania are pursuing non-murder charges against Mangione relating to the items allegedly found on him.

Federal prosecutors, meanwhile, are pursuing a separate murder case that carries the threat of the death penalty; the prosecutors have not yet said whether they plan to pursue that or life behind bars.

But it is the New York state case that has attracted the most fanfare thus far. In December, state officials flew Mangione into Manhattan for his arraignment by helicopter, with New York City Mayor Eric Adams personally accompanying him to the courthouse alongside packs of heavily armed police officers.
