The suspected assassin of the UnitedHealthcare CEO has been compared to the Unabomber.

The murder of UnitedHealthcare CEO Brian Thompson by Luigi Mangione, a wealthy Maryland family member who graduated from the University of Pennsylvania and served as the prep school valedictorian, has led some to compare him to Ted Kaczynski, the Unabomber.

"John Kelly, a criminal profiler and the president of System to Apprehend Lethal Killers, stated that both the Unabomber and the other killer sent messages through their violent actions. The Unabomber specifically targeted the technology industry and conveyed his message about the destructive potential of technology."

The Unabomber, also known as the FBI shorthand for the university and airline bomber, was the first case that Kelly worked on. Over a period of nearly 20 years, he sent 16 bombs, one of which exploded on a plane after it reached a certain altitude.

He added, "I suspect the UnitedHealthcare message he sent to the insurance industry won't be his last unless he gets caught."

The suspected murder weapon in Thompson's slaying was made with homemade, 3D-printed parts, according to Kelly.

A "ghost gun" with a plastic receiver and suppressor was described by the police.

""Both could have suffered from schizophrenia, including the Unabomber. Luigi is at the age where it could begin," Kelly said."

Last year, Kaczynski took his own life in prison after deciding not to undergo cancer treatment. He was given a life sentence without the possibility of parole following his brother's submission of his manifesto to the Washington Post in 1995, which led to his arrest.

According to reports, Mangione was arrested in Altoona, Pennsylvania, on Monday and had a handwritten manifesto that allegedly mentioned UnitedHealthcare and the shareholder conference where Thompson was attending at the time of the assassination.

Kelly stated that both individuals were fixated on industries they aimed to harm and draw attention to through public awareness.

On Goodreads, a literature-centric social media platform, Mangione frequently posted and wrote a review of Kaczynski's manifesto.

"Although it may be tempting to dismiss his ideas as the ramblings of a madman to avoid confronting the uncomfortable truths he highlights, it is impossible to ignore how accurate many of his predictions about contemporary society have proven to be."

He quoted an interesting "take" on Kaczynski's "Industrial Society and Its Future" that he found online.

"In the event that all other means of communication fall short, violence becomes necessary for survival," he stated. "Although you may not agree with his tactics, from his point of view, it is not terrorism, but rather war and revolution."

He praised the lone-wolf serial bomber as a "mathematics prodigy."

"He was a violent individual who was rightfully imprisoned for maiming innocent people. Although these actions are often associated with a crazy Luddite, they are more accurately seen as those of an extreme political revolutionary."

Both men had become reclusive before their alleged crimes. Kaczynski lived in a remote cabin with no electricity or running water to escape the society he despised. Mangione's mother reported him missing to San Francisco police last month, stating that she hadn't been able to reach him since July, according to law enforcement sources.

The business address where she thought he worked was permanently closed.

"According to former FBI agent Nicole Parker, "He becomes a recluse," which is when he starts defining his identity and ultimately leads him down a path of violence. However, it's important to note that this behavior was not sudden and the individual had likely been thinking this way beforehand."

But she questioned whether the suspected killer really did act alone.

"She informed Planet Chronicle Digital that she wanted to view the call history on the burner phone. "These emotions didn't arise yesterday or three months ago. The inner thoughts he had? No.""

Kaczynski, like Mangione, was a Harvard graduate and mathematician who, between 1978 and 1995, killed three people and injured 23 more with a series of bombs he mailed to his victims.

A masked assassin was caught on surveillance video sneaking up behind Thompson on the sidewalk outside a Midtown Manhattan Hilton hotel at approximately 6:45 a.m. on Dec. 4. Thompson, who was heading to a shareholder conference at the venue, was shot by the gunman who had positioned himself behind him.

A woman fled the scene after witnessing the CEO's collapse, while the masked figure casually walked away. Police tracked his movements in New York City and eventually arrested him at a McDonald's in Altoona, Pennsylvania, after recognizing him from surveillance images that circulated online.

In Pennsylvania, Mangione is being held without bail on multiple charges. His lawyer announced this week that he will contest extradition to New York, thereby postponing the second-degree murder case there.

The police are investigating a potential motive and are looking into whether he had a health care claim denied.

It is claimed that Mangione confessed to the crime in writing and also left behind other evidence, such as bullet casings with the words "deny," "defend," and "depose" on them, as well as a backpack filled with Monopoly money.

The notes on the bullet casings resemble the book "Delay, Deny, Defend: Why Insurance Companies Don't Pay Claims and What You Can Do About It," but it is not listed on the suspect's Goodreads account. Police reported on Wednesday that the casings match the handgun found during Mangione's arrest.

"Parker stated that the shooter had sympathy for an individual and used violence for a cause, which took a long time to develop. The shooter had the intelligence and sophistication to carry out the act, exhibiting traits of someone willing to go to extreme measures for their passion. They believed they were standing up for their cause and self-identity by saving people from the health care insurance industry."
