A homeless Redditor helped crack the case of the Brown University and MIT professor shootings that took place on December 13 and December 15 respectively. The Redditor, known only as 'John,' claimed he encountered suspect Claudio Neves Valente in the bathroom of Brown’s engineering building just hours before the attack. 'The police need to look into a grey Nissan with Florida plates, possibly a rental,' he wrote in his post. #news #crime #truecrime #brownuniversity
