Police said a handwritten document was found with Luigi Mangione, the 26-year-old man arrested as a person of interest in the killing of UnitedHealthcare CEO Brian Thompson in New York, during his arrest in Altoona, Pennsylvania, on Monday.
After the Altoona Police Department confirmed it arrested a person who a McDonald’s employee said matched the description of Thompson’s killer, New York Police Department (NYPD) Commissioner Jessica Tisch confirmed in a press conference on Monday that Altoona police arrested Mangione, finding weapons and clothing consistent with those worn by the killer, as well as a “handwritten document” that allegedly explains Mangione’s motivations.
The commissioner confirmed, “Officers recovered a handwritten document that speaks to both his motivation and mindset.”
NYPD Chief of Detectives Joe Kenny said the department has yet to review the material recovered from Mangione (pictured above) during the arrest, but described his writings as a three-page, handwritten document, which Kenny said indicates Mangione “has some ill will toward corporate America.”
The chief of detectives added, “that will all come out as part of our investigation. ”
According to The New York Post, Mangione described corporate executives as parasites within the document, which law enforcement sources reportedly called a manifesto. The outlet claimed Mangione may have been motivated by the plight of a sick loved one.
Mangione was also sporadically active on the social media platform X, as well as the website GoodReads, where the suspected killer wrote nearly 300 book reviews using a now-private account.
One book that drew Mangione’s interest was reportedly “Industrial Society and Its Future,” the manifesto left by Ted Kaczynski, who killed three Americans and injured dozens with homemade explosives over a two-decade period.
“It’s easy to quickly and thoughtless[ly] write this off as the manifesto of a lunatic, in order to avoid facing some of the uncomfortable problems it identifies. But it’s simply impossible to ignore how prescient many of his predictions about modern society turned out,” Mangione wrote of Kaczynski’s book in January, according to CNN.
While the alleged killer described Kaczynski as “violent” and acknowledged he was “rightfully imprisoned,” he posited Kaczynski’s actions should “more accurately seen as those of an extreme political revolutionary.”
The Pennsylvania Daily Star filed a Right to Know Request with Altoona, Pennsylvania to obtain copies of the three-page document authorities said Mangione had on his person at the time of his arrest.
