The eight-time jiu-jitsu world champion was murdered in cold blood in Sao Paulo, Brazil, early Sunday. Leandro Lo Pereira do Nascimento (known as Leandro Lo), 33, was attending a concert at Club Sirio, an exclusive club in South Paulo, when "a man he argued with" shot him in the head. According to witnesses at the scene of the crime, the world champion pinned down the man, who was drunk, in a "typical martial arts armlock" to calm him down, <a href="https://www.marca.com/en/more-sports/2022/08/07/62efe90322601de13e8b4597.html" target="_blank" rel="noopener">MoreSports</a> reported. After Lo relented, the man pulled out a gun and shot the jiu-jitsu wrestler in the head. According to authorities, the assailant is currently a fugitive and has been identified by the Sao Paulo military police. Following the shooting, Lo was transferred to a <a href="https://www.westernjournal.com/electric-bus-spontaneously-catches-fire-black-smoke-fills-air-3-sent-hospital/" target="_blank" rel="noopener">hospital</a>.
