Following the arrest of 26-year-old Luigi Nicholas Mangione, who has been named a "strong suspect" in the targeted murder of UnitedHealth CEO Brian Thompson, the public has been clamoring for details about his background.

What we know so far is that he is a UPenn graduate whose last known residential address is in Honolulu, Hawaii. He also graduated from the Gilman School in 2016 as valedictorian and went on to earn both a bachelor's and master's degree in engineering with a focus on AI.
