The 26-year-old suspect arrested for last week’s brazen shooting of an insurance company executive suffered from chronic back pain severe enough to require surgery.

Luigi Mangione was detained at a McDonald’s in Altoona, Pennsylvania after a witness reported to police that he looked similar to the man wanted in the Manhattan assassination of Brian Thompson, CEO of UnitedHealthcare. Mangione was initially held on gun charges, and later charged with murder by New York City police.  

"He matches the description of the person we are looking for," NYC mayor Eric Adams said in a news conference.

Mangione had a handgun and a silencer that were "consistent with the weapon used in the murder," according to NYPD Commissioner Jessica Tisch.

He also had several fake IDs and a handwritten manifesto that explained his motives. Police sources told the New York Post that Mangione hated the U.S. healthcare system.

“These parasites had it coming,” the manifesto reportedly says. “It had to be done.”

Mangione is a graduate of the University of Pennsylvania, where he majored in computer science and received a master's degree in engineering.

In his online accounts, Mangione wrote about artificial intelligence and reposted links about psychedelics and mental health. He also shared that he suffered from spondylolisthesis, a chronic condition where vertebrae in the spine slip out of place and cause back pain.

Mangione’s profile on Twitter/X includes an x-ray image of several screws embedded in a spine. It appears to be his own x-ray. A second image shows a smiling and seemingly fit Mangione hiking bare-shirted in Hawaii.

A friend and former roommate of Mangione said he had to spend several days in bed after aggravating his back during a surfing lesson in Hawaii.

“He was in bed for about a week. We had to get a different bed for him that was more firm,” R.J. Martin told CNN’s Erin Burnett. “And I know it was really traumatic and difficult. You know, when you're in your early 20’s and you can't do some basic things, it can be really, really difficult.”

Martin said Mangione was thoughtful, friendly and communicated well. The two fell out-of-touch when Mangione left Hawaii, but exchanged texts earlier this year.

“I knew he was going to have a surgery. So earlier this year, I checked in with him. He confirmed that he had had surgery, and he sent me the X rays. It looked heinous with just giant screws going into his spine,” Martin said.

“After that, he called me once and I didn't pick up. We kind of texted a little bit, but we lost contact unfortunately. I feel terrible now. I wish I would have made more of an effort to communicate with him.”

‘Violence Is Necessary to Survive’

While in Hawaii, Martin says Mangione started a book club with his roommates. His profile on Goodreads shows a particular interest in back pain. He listed five books about it, including “Back in Control: A Spine Surgeon's Roadmap Out of Chronic Pain” by Dr. David Hanscom and “Crooked: Outwitting the Back Pain Industry and Getting on the Road to Recovery” by Cathryn Jakobson Ramin.

Ramin wrote about the excessive use of epidural steroid injections, calling them the “bread and butter” treatment of interventional pain doctors.

Hanscom wrote his book to explain why he abandoned his 30-year career as a spine surgeon. He was seeing too many patients being harmed by interventional procedures.

“Modern medicine is ignoring this. We are not only failing to treat chronic pain, but creating it,” Hanscom wrote in a PNN column. “Spine surgeons are throwing random treatments at symptoms without taking the time to know a patient’s whole story.” 

On Goodreads, Mangione reviewed the manifesto of “Unabomber” Theodore Kaczynski, the reclusive hermit who planted bombs that killed three people before being caught in 1996. His words suggest that Mangione saw Kaczynski as a counterculture hero who rebelled against an unjust society.

“He was a violent individual - rightfully imprisoned - who maimed innocent people,” Mangione wrote. “While these actions tend to be characterized as those of a crazy luddite, however, they are more accurately seen as those of an extreme political revolutionary.

'When all other forms of communication fail, violence is necessary to survive. You may not like his methods, but to see things from his perspective, it’s not terrorism, it’s war and revolution.'

It’s not known if Mangione’s back pain became worse after his surgery or what role, if any, United Healthcare had in his treatment.

His friend Martin was shocked by Mangione’s arrest and alleged involvement in murder.

“I can make zero sense of it. You know, there's never justification for violence. We live in a democratic system with processes and procedures to address our issues. I can make no sense of it,” he said.

If Mangione did resort to violence against the healthcare system, he wouldn’t be the first patient to do so. In recent years, doctors in Indiana, Nevada and Oklahoma have been shot by disgruntled pain patients or their spouses.
