On Monday, Luigi Mangione, charged with the assassination of UnitedHealthcare CEO Brian Thompson, made his way back to court. His legal team is set to argue in a series of three hearings for the exclusion of certain evidence connected to the high-profile case.

The 27-year-old, who graduated from an Ivy League school, faces allegations of having followed the 50-year-old Thompson—father of two—before purportedly shooting him from behind near a Manhattan hotel.

Thompson, a Minnesota resident, had plans to participate in a shareholder meeting later that morning.

Mangione’s defense is seeking to have evidence excluded that was gathered during his capture at a McDonald’s in Pennsylvania, five days post-murder. This evidence involves items found in his backpack, such as the alleged murder weapon and personal journals, alongside statements made to police prior to being read his Miranda rights.

The hearings are anticipated to unfold over several days, with a pause scheduled for Wednesday.

There are three different types of suppression hearings — Mapp, Huntley and Mosley. Two of them are expected this week: a Mapp hearing, to determine whether certain types of physical evidence should be suppressed or thrown out, and a Huntley hearing, to determine if a confession or other statements to law enforcement are admissible.

The Manhattan District Attorney’s Office has not yet finalized its trial strategy, and a Mosley hearing, which determines if non-eyewitnesses can testify at trial, is not expected yet.

Mangione faces a slew of charges in New York, Pennsylvania and federally.

State-level terror charges were thrown out earlier this year, but Mangione still faces second-degree murder, seven counts of criminal possession of a weapon, and possession of a forged ID in New York.

He faces a maximum of life in prison in the Empire State.

If convicted on the top federal charges, he could face the death penalty.
