Suspect in Ivy League Killings Was a Rejected M.I.T. Hopeful

Former classmates of a man accused of a triple homicide say his anger grew after failing to get into the prestigious university he admired. Claudio Neves Valente is charged with killing two Brown University students and an M.I.T. professor. People who knew him years ago describe a sharp decline. They say Valente desperately wanted to attend the Massachusetts Institute of Technology. His rejection from M.I.T. deepened his existing resentments, according to their accounts. The suspect's transition from a bright student to an isolated loner is now a focal point of the investigation. Authorities have not stated an official motive for the shootings.
