STORY: The suspect in last weekend's mass shooting at Brown University is dead from a self-inflicted gunshot wound, with investigators certain he also killed a Massachusetts Institute of Technology professor two days later, officials said on Thursday (December 18).

The gunman, identified as Portuguese national Claudio Neves Valente, 48, was found dead Thursday night in a storage rental facility in Salem, New Hampshire, where he had rented a unit last month, officials said.

Valente attended Brown University more than two decades ago as a Ph.D. student in physics and was a former classmate in Portugal of slain MIT professor Nuno Loureiro, 47. Despite those links, authorities said that his motive in the killings remains a mystery.
