The FBI said on Wednesday it had determined the suspected gunman behind December’s fatal mass shooting at Brown University spent years planning the attack and was “driven by an accumulation of grievances that he collected throughout his life.”
The FBI’s Boston division detailed investigators’ assessment in a joint announcement with federal prosecutors in Massachusetts after concluding a significant portion of their probe into the accused gunman, Claudio Neves Valente.
Authorities say the 48-year-old Portuguese national slipped into an engineering building on the Ivy League campus on December 13 and opened fire with a handgun, killing two students and injuring nine others.
He went on to kill a Massachusetts Institute of Technology professor, Nuno Loureiro, in a separate shooting at his home outside Boston on December 15, authorities say. Neves Valente was found dead from a self-inflicted gunshot wound on December 18 at a New Hampshire storage facility following a manhunt.
Prosecutors had in January released transcripts of video recordings Neves Valente made before his death in which he admitted to planning the attack. But prosecutors said he did not provide a motive for targeting his victims.
