Investigators turned on Friday to the search for a motive in the murders of two Brown University students and a physics professor in Massachusetts in separate but linked attacks, after the prime suspect was found dead from an apparently self-inflicted gunshot wound.
The body of Claudio Manuel Neves Valente, 48, a Portuguese national and formerly very briefly a student at Brown, was discovered in a New Hampshire storage facility on Thursday night after a five-day manhunt.
