The blade-wielding Pennsylvania man shot dead by police — triggering destructive protests demanding justice — was previously busted in 2019 for knifing four people in the city, according to his lawyer and officials. Before Ricardo Munoz, 27, made the fatal decision to rush a cop while waving a knife on Sunday, he was charged with stabbing or slashing two men, a woman and a 16-year-old boy in and near a Lancaster home in March of last year. “He is the individual who was shot yesterday,” confirmed public defender Elizabeth Low, who represented Munoz in the aggravated assault case.
