THE suspected assassin of the UnitedHealthcare CEO praised the deranged Unabomber months before he allegedly killed Brian Thompson.
Luigi Mangione, 26, has been charged with murder as a number of chilling revelations have emerged since his identity was uncovered on Monday.
Mangione was revealed to be a wealthy and privately educated man with online sleuths quickly noticing his love for reading and online books.
This has led people to discover he appeared to use a book recommendation website called Goodreads prior to being arrested.
One harrowing review left behind by the suspected masked murderer was on a 1995 essay by Ted Kaczynski - the man known as the Unabomber.
Kaczynski launched a 17-year terror campaign starting in 1978 that saw him send bombs in the mail across the US.

He left the essay a four-star rating on the website alongside a haunting message seemingly in support of the domestic terrorist.
It read: "You may not like his methods, but to see things from his perspective, it’s not terrorism, it’s war and revolution."
Kaczynski's work was speaking on the subject of fossil fuel companies, widely criticising the way these organisations work.
Mangione's review showed he strongly agreed as he blasted certain companies for "actively suppressing" negative comments.
He added that people need to start to understand that peaceful protests are "outright ignored".
And that "violence against those who lead us to such destruction" should be "justified as self-defense".
The account has not been confirmed as Mangione's but the username was the same as what has been seen on his other social media sites.
Another similar sinister message from the account quoted a separate post from another user about how "violence is necessary to survive".
Mangione shared the original quote and called them “interesting” on a thread about the work of Kaczynski.
The suspected CEO assassin did label the Unabomber as a "violent individual - rightfully imprisoned" in a message on Goodreads.
But he also said he should be viewed as an "extreme political revolutionary” opposed to a lunatic.
Mangione left his own strongly worded and threatening manifesto which cops uncovered during his arrest on Monday.
Police swooped on him in a McDonald's in Pennsylvania as they found a ghost gun similar to the murder weapon and documents that appeared to be linked to the killing on him.
One handwritten document is said to have indicated "motivation and mindset" and scolded the healthcare industry, according to police.
The manifesto reportedly said: "These parasites had it coming.
"I do apologize for any strife and trauma, but it had to be done."
A note also saw him reportedly admit that he acted alone and was self-funded, cops who saw the document told .
Investigators are said to have had no hunch that Mangione could have been the killer with him not even being on their wanted suspect list.
His capture was a complete surprise as the NYPD thanked a McDonald's worker who phoned the cops alerting them of his presence.
It comes as cops are continuing to look into a number of leads following Mangione's capture.
One of the latest theories behind why he may have become a killer involves his pals claiming he turned "absolutely crazy" after an agonising back surgery.

Who is Luigi Mangione?

He was born and raised in Maryland where he was valedictorian of his high school graduating class at Gilman School in Baltimore.
He had no prior criminal history and was said to have been a model student, footballer and all-round athlete at high school.
One former student from the Gilman School told The U.S. Sun Mangione was "popular" and had a "big circle of friends."
The former student, who asked not to be identified, said: "We went to the same school but didn't really have the same friends. I'm really shocked by this whole thing.
"I think he played soccer, it was an all-boys school, so being a good athlete got you social currency for sure."
After, Mangione graduated cum laude from the University of Pennsylvania, where he studied Computer and Information Science, according to his LinkedIn profile.
He also got his masters from the Ivy League school.
Mangione was reportedly a data engineer at a car company in California before moving to Hawaii.
