The suspect questioned in connection with the assassination of American insurance executive Brian Thompson was an Ivy League student who believed the Unabomber was an “extreme political revolutionary.”

Luigi Mangione, 26, was reading at a McDonald’s in Altoona, Pennsylvania, on Monday morning when an employee recognized him and tipped off authorities.

The six-day manhunt for the New York bomber culminated in Mr. Mangione being found with a three-page manifesto, a ghost gun – a homemade firearm – and a silencer. He also had his passport and the fake ID the suspect used to check into a hostel on the Upper West Side.

He wore clothing that matched the suspect, and his manifesto showed that he harbored “ill will toward corporate America” and had allegedly voiced grievances toward the health care industry.

Police Commissioner Jessica Tisch said it was believed Mr Mangione was “the person of interest”.

The suspect now faces firearms charges in Pennsylvania and authorities will work to bring him to New York to face additional charges, New York Police Department Chief Detective Joseph Kenny said. No charges have yet been filed against Mr. Mangione.

Mr. Mangione, a powerful math genius from Maryland, had apparently long wanted to make his mark on the world.

In a social media post, he said he was always “annoyed” in math class because “all the low-hanging questions had been solved before I was born.”

He added that he was now grateful for his “21st century education” and would focus on topics such as “evolutionary psychology, primitive neuroscience and information networks.”

After graduating valedictorian of his high school class in 2016 at the Gilman School in Baltimore, which costs about $40,000 a year, Mr. Mangione went on to study computer science at the University of Pennsylvania, one of the most prestigious universities in America.

He then worked as a data engineer for TrueCar and lived in California and later Honolulu, Hawaii, according to LinkedIn.

According to his Goodreads account, Mr. Mangione was sympathetic to Ted Kaczynski, the Unabomber, whom he described as a “mathematical prodigy.”

In his review, “Industrial Society and Its Future, the Unabomber Manifesto,” he wrote: “It is easy to quickly and thoughtlessly dismiss this as the manifesto of a madman in order to avoid confronting some of the unpleasant problems it identifies.” But it’s simply impossible to ignore how prescient many of his predictions about modern society were.

“He was a violent individual – lawfully imprisoned – who mutilated innocent people. While these actions are more accurately characterized as those of a crazed idiot, they are more aptly viewed as those of an extreme political revolutionary.”

Mr. Mangione went on to share an online sentiment that he described as “interesting” that read: “When all other forms of communication fail, violence is necessary to survive.” You may not like his methods, but if you take things out From his perspective, it is not a matter of terrorism, but of war and revolution.”

They went on to criticize fossil fuel companies, adding: “They have no qualms about burning the planet for a dollar. So why should we be concerned about burning them down to survive?”

“We are animals like everything else on this planet, except we have forgotten the law of the jungle and bend for our overlords, while any other animal would recognize the threat and fight to the death for survival. ‘Violence has never solved anything’ is a statement made by cowards and predators.”

Mr. Mangione’s social media accounts are full of commentary on the state of society and mental health.

In a post on characters and perform anime dances for them”.

Mr. Mangione also republished comments on a book called “The Anxious Generation” and the impact of “seasonal and circadian rhythms” on mental health.
