The suspect in the shootings that killed two Brown University students and a Massachusetts Institute of Technology professor left behind videos that provide some new insight into what might have driven him, according to a transcript of video footage released by federal law enforcement officials on Tuesday.
The suspect, Claudio Neves Valente, made the videos before taking his own life in a storage facility in Salem, N.H., and investigators found them on Mr. Neves Valente’s devices.
They were recorded in Portuguese, and the authorities had the videos translated to English.
