Investigators are trying to sort out why a former Brown University student allegedly opened fire on the campus decades after he dropped out and later gunned down an esteemed Massachusetts college professor he attended school with in Portugal in the 1990s. Authorities say Claudio Neves Valente was found dead Thursday night in New Hampshire from a self-inflicted gunshot wound. Investigators believe he opened fire in a Brown lecture hall last Saturday, killing two students and wounding nine others, before heading to the Boston area and killing Massachusetts Institute of Technology professor Nuno F.G. Loureiro on Monday. He was a Brown graduate student from fall 2000 until spring 2001, and he and Loureiro attended the same Portuguese academic program before that.
