Brown University Gunman Planned Attack for Years, F.B.I. Says

The man who killed two Brown University students and an M.I.T. professor last December plotted the crimes over the course of three years, federal law enforcement officials said Wednesday.

The shooter, Claudio Neves Valente, 48, had been socially isolated, making it hard to track his intentions, investigators said in a report released on Wednesday that shed some new light into the crimes.

On Dec. 13, Mr. Neves Valente, a Portugal native and legal permanent U.S. resident who had been living in Miami, fired multiple shots in a lecture hall at Brown, in Providence, R.I. Two students, MukhammadAziz Umurzokov and Ella Cook, were killed. Two days later, he fatally shot an M.I.T. physicist, Dr. Nuno Loureiro, in Brookline, Mass.

Mr. Neves Valente then drove to New Hampshire, where he died by suicide in a storage facility. Police officers on Dec. 18 found his body, two guns and rambling video recordings in which he acknowledged he was the shooter but expressed no remorse.
