Luigi Mangione, United Healthcare CEO murder suspect, shared a quote from Indian philosopher Jiddu Krishnamurti

UnitedHealthcare CEO Brian Thompson was shot dead by a masked gunman outside a New York City hotel last week in an apparent assassination that has gripped the public’s imagination. Police in the US state of Pennsylvania on Monday arrested 26-year-old Luigi Nicholas Mangione.

Luigi Nicholas Mangione apparently was living a charmed life: the grandson of a wealthy real estate developer, valedictorian of his elite Baltimore prep school and with degrees from one of the nation's top private universities.

Investigators say the words "deny", "defend" and "depose" were written on shell casings found at the scene of Brian Thompson's murder. Law enforcement sources say this may be a reference to the "three Ds of insurance" - tactics used by companies to reject payment claims by patients, according to BBC.
