'Parasites had it coming': Police say incriminating document found on CEO shooting suspect

CNN reported on Monday that the suspected shooter of UnitedHealthcare CEO Brian Thompson had two pages of writing with him upon arrest.

Luigi Mangione was taken into custody at a McDonald's in Pennsylvania. CNN quoted law enforcement sources as saying a document seized off of him reads, "These parasites had it coming."

Another comment in the document read, "I do apologize for any strife and trauma, but it had to be done."

“We don’t think there’s any specific threats to other people mentioned in that document, but it does seem that he has some ill will towards corporate America,” NYPD Chief of Detectives Joseph Kenny said during a briefing, CNN reported.

He was also in possession of a ghost gun that may have been 3D printed, police also said.
