Lisbon
—
Former neighbors paint a mixed portrait of Claudio Neves Valente, whose motives remain a mystery more than a week after police say he killed two Brown University students and an MIT professor, portraying a “very bright” but reclusive young man who was estranged from his family and whose mother once told a neighbor that her son “needs help.”
CNN visited the apartment building that Neves Valente, a native of Portugal, lived in as a student more than two decades ago before moving to the United States. The brown, cream and gray high-rise in Olivais, a modest middle-class neighborhood in eastern Lisbon, looks much like others in the area.
