Luigi Mangione's lawyers have unveiled a new strategy ahead of his murder trial, announcing that they plan to change his plea to deploy a psychiatric defense, arguing that he was 'extremely emotionally disturbed' at the time of the alleged killing. 

Mangione's representation presented the strategy at a pre-trial hearing on Wednesday, according to the presiding judge, Gregory Carro. 

In response to the change of plea, Carro has ordered the defense to produce Mangione's psychiatric records immediately, meaning they would also be unsealed to the public. 

In order for his attorneys to deploy a psychiatric defense, they typically must formally withdraw a prior plea. Mangione had previously pleaded not guilty to the charges against him.
