The most recent widely reported incident being referred to as the “MIT shooting” is the killing of MIT professor Nuno Loureiro at his home in Brookline, Massachusetts, on the night of December 15, 2025 (he died at the hospital the next morning).

Key timeline

  • The linked case involves two connected events: a mass shooting at Brown University on December 13, 2025, and the fatal shooting of an MIT professor on December 15, 2025.
  • Authorities later confirmed that both incidents were carried out by the same suspect, Claudio Manuel Neves Valente, who was later found dead in a New Hampshire storage unit on December 18, 2025.

Clarification about MIT campus

  • The professor was affiliated with MIT, but the shooting itself took place at his residence in Brookline, not on the MIT campus.
  • There have also been earlier, unrelated “near MIT” shooting alerts and reports (for example in 2015 and 2025) that caused some confusion online, which may be why people phrase searches as “MIT shooting.”
