Alejandro Romero, who went to college with him and was in Discord groups (a social platform where people share content), told NBC News he used to play Among Us, a game where “crewmates” try to weed out the “imposters” whose role is to kill crewmates without being detected, with Mangione and was shocked by the news of Luigi’s arrest. Freddie Leatherbury, a former Gilman classmate of Mangione, told The New York Times that Mangione played soccer and ran track and field or cross-country in high school. In January, Mangione posted on the book review platform, Goodreads, that he had read Ted Kaczynski, the Unabomber’s book, “Industrial Society and Its Future,” giving it a four star review, The New York Times reported.
