Luigi Mangione's legal team argues New York state case against him should be dropped

Lawyers for Luigi Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson in December, have filed a motion to dismiss the New York state murder charges against him, arguing that the case and federal charges against him mean he faces double jeopardy.

Lawyers for Luigi Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson in December, have filed a motion to dismiss the New York state murder charges against him, arguing that the case and federal charges against him mean he faces double jeopardy.

Mangione, 26, pleaded not guilty last week to federal stalking and murder charges. He could face the death penalty if convicted.

In a 57-page filing in New York's Supreme Court, attorney Karen Agnifilo argues that Mangione should not face the state charges against him, which include first-degree murder in furtherance of terrorism. He also faces charges in Pennsylvania, where he was arrested five days after the Dec. 4 shooting outside a midtown Manhattan hotel.

"As a result of unprecedented prosecutorial one-upmanship, Mr. Mangione now faces three simultaneous prosecutions in three different jurisdictions — one of which is seeking the death penalty, while another is seeking life imprisonment — all for one set of facts,” Agnifilo wrote in the Thursday filing.

The filing also moves to suppress Mangione's statements to law enforcement officers during his arrest in Pennsylvania because, according to Agnifilio, officers failed to read him his Miranda rights.
