During his time at Brown, Neves Valente was enrolled only in physics classes, and it is likely that he would have taken courses and spent time in Barus & Holley, where the vast majority of physics courses take place in classrooms and laboratories. Detailed records indicating where classes were held don’t extend back to 2001.”
During the shooting at Brown University, Valente gunned down sophomore Ella Cook and freshman Mukhammad Aziz Umurzokov. He wounded nine other people during his deadly rampage at Brown University's Providence campus in Rhode Island on Saturday, December 13.

I want to thank the dedicated city, state and federal law enforcement agencies that worked tirelessly on this case. We hope this brings an increased sense of safety for our community.”
