Luigi Mangione's notebook reveals he considered bombing Brian Thompson but...

As investigators already said that the murder of Brian Thompson, the CEO of UnitedHealthcare was not rushed, police have now found a handwritten murder plot from suspected killer Luigi Mangione's notebook where he jotted down a 'to do' list for the murder. It shows firing from his old-fashioned gun was not the first idea that came to him. Mangione weighed over ways to kill the CEO. He also wrote that killing Thompson with a bomb would have killed many innocents.

This handwritten note is different from the three-page manifesto in which Mangione apologized for the strife that he was going to cause and also mentioned that he was working alone.

'You wack the CEO'

In his notebook, Mangione deliberated: "What do you do? You wack the CEO at the annual parasitic bean-counter convention. It's targeted, precise, and doesn't risk innocents,"

It's not yet known how he got the gun and how he got the specific timing of Brian Thompson's arrival at the hotel that he executed what he considered a mission.

Fingerprints match

Law enforcement officials said fingerprints collected at the scene of the assassination of Thompson and those taken in the arrest of Mangione matched marking the first positive tie between the person of interest and the murder.

Mangione's lawyer denied his client's involvement in the killing and said there was no evidence tying him to the murder. The lawyer said Mangione plans to plead not guilty to Pennsylvania charges related to a gun and fake ID police found when they arrested him in Altoona. “I haven’t seen any evidence that they have the right guy,” Thomas Dickey told CNN’s Kaitlan Collins on “The Source.” On ABC’s “Good Morning America” Wednesday, Dickey reiterated he had not seen the evidence, including writings police said were in Mangione’s possession at the time of his arrest. Mangione – who faces a slew of charges in New York and Pennsylvania – was denied bail at an extradition hearing Tuesday afternoon at the Blair County Courthouse in Pennsylvania.

New York prosecutors charged Mangione with one count of murder, two counts of second-degree criminal possession of a weapon, one count of second-degree possession of a forged document, and one count of third-degree criminal possession of a weapon, online court documents show.
