The shocking Brown University campus shooting and the murder at an MIT professor's home a few days ago turned out to have been committed by the same person. Suspect Claudio Valente (deceased by suicide), 48 years old, Portuguese, was a PhD student at Brown University from 2000-2001 but seemingly did not complete his degree. So, never mess with a PhD student because they're all mentally unstable (including me). A PhD's revenge is never too late.
