Luigi Mangione, who has been accused of shooting Brian Thompson the CEO of UnitedHealth, now has a legal expert in death penalty cases added to the defense team.

On Tuesday, Federal Judge Katherine Parker ruled that Avraham Markowitz, who is an expert in capital cases, will review and examine his case.

One of his federal charges against him is for murder with a firearm, which qualifies for the death penalty.

The accused, who is only 26-years-old, is charged for brutally shooting the 50-year-old CEO on December 4 near Hilton hotel in Midtown Manhattan while Brian was on his way for a conference.

While talking to ABC News, Karen Friedman Agnifilo, who is the spokesperson for his attorney, expressed how "pleased" she is to have Avraham on the case.

"The Agnifilo Intrater team is pleased to have Avi Moskowitz lend his considerable expertise in death penalty cases to Mr. Mangione's federal case as 'learned counsel,'" the spokesperson for the firm stated. "The charges could not be more serious and our client needs every resource at his disposal to fight these unprecedented charges in three jurisdictions."

Currently placed in custody at Brooklyn's infamous Metropolitan Center, Luigi denied and pleaded not guilty to 11 charges against him, including first-degree murder and murder as an act of terrorism.
