BALTIMORE (WBFF) -- As more evidence comes to light about Luigi Mangione and the murder charges, more details emerge about the alleged manifesto found with Mangione.
The gun found on the suspect in the killing of UnitedHealthcare CEO Brian Thompson matches shell casings found at the crime scene, New York's police commissioner said Wednesday.
Commissioner Jessica Tisch also said lab results matched suspect Luigi Mangione's prints to a water bottle and protein bar wrapper found near the scene of the killing.
While little information has come out regarding a clear motive, some experts have speculated based on a reported manifesto found. Independent journalist Ken Klippenstein published what's being reported as the entire manifesto, showing Mangione's discontent with the healthcare industry.
"I do apologize for any strife of traumas but it had to be done. Frankly, these parasites simply had it coming. A reminder: the US has the #1 most expensive healthcare system in the world, yet we rank roughly #42 in life expectancy," Mangione allegedly wrote. "United is the [indecipherable] largest company in the US by market cap, behind only Apple, Google, Walmart. It has grown and grown, but as our life expectancy? No the reality is, these [indecipherable] have simply gotten too powerful, and they continue to abuse our country for immense profit because the American public has allowed them to get away with it."
R.J. Martin, a former roommate of Mangione at a co-living situation in Hawaii, told CNN he knew Mangione had a back injury that caused debilitating pain sometimes. Martin said he checked in with Mangione to learn he did have surgery. Photos of an X-ray posted to Mangione's X - formerly known as Twitter - show a back with several pins or screws in a spine.
"He sent me the X-rays; it looked heinous with just giant screws going into his spine. After that he called me once I didn't pick up. We kind of texted a little bit but we, you know, unfortunately, I feel terrible now, I wish I would have made more of an effort to communicate with him," Martin told CNN.
Mangione's defense attorney, Thomas Dickey, said he will be fighting the extradition to New York; the defense has two weeks to file the appropriate paperwork with the court in Pennsylvania. New York Gov. Kathy Hochul said she will sign a governor's warrant requiring the extradition of Mangione.
"We're going to take one step at a time, it's a long process," Dickey told reporters Tuesday during a news conference.
In addition to second-degree murder in New York, Mangione is facing two counts of second-degree criminal possession of a weapon, third-degree criminal possession of a weapon, and second-degree criminal possession of a forged instrument.
"The reason that Mr. Mangione was charged with second-degree murder as opposed to first- degree murder is actually that in New York State, in order to be charged with first degree murder, it requires a very specific type of victim. For instance, a police officer, a firefighter or a witness," explained Jeremy Eldridge, a Baltimore area trial attorney. "What Mr. Mangione is accused of really is more second-degree murder in New York, which is the intentional killing of another human."
They [prosecutors] could always add that charge if they believed that it qualified, Eldridge continued.
Eldridge said he expects the murder trial in New York to unfold first. In Pennsylvania, Mangione is facing firearms and forgery charges, along with giving false information to law enforcement. Dickey said his client pleaded not guilty to the charges in Pennsylvania.
During the extradition hearing Tuesday, Dickey told Mangione to stop talking, which is something Dickey said will be case moving forward.
"As long as I'm going to be his lawyer, I'm going to do all the talking. My client's not going to say anything," Dickey explained.
Currently, Mangione is scheduled for a preliminary hearing on Dec. 23, though it's possible that gets rescheduled depending on the extradition process or other developments. Dickey did not say whether he intends to have the preliminary hearing moved. Mangione remains jailed in Pennsylvania.
Meanwhile, Luigi Mangione's cousin, Del. Nino Mangione, canceled a fundraiser scheduled for Dec. 13 that was supposed to be held at Hayfields Country Club in Baltimore County. The Mangione family owns the club, along with Turf Valley Resort in Ellicott City, Lorien nursing homes, and a talk-radio station.
Luigi Mangione was valedictorian in 2016 when he graduated from The Gilman School, an all-boys, private school in Baltimore City. He then became an Ivy League student, graduating with his Bachelor's and Master's Degrees in computer science from the University of Pennsylvania.
