“These were like-minded people who used this chat group to talk about their shared interests in racial hatred, replacement theory and hatred of anyone who is Jewish, a person of color or not of European ancestry,” said one of the two law enforcement officials with close knowledge of the investigation. “What is especially upsetting is that these six people received advanced notice of the Buffalo shooting, about 30 minutes before it happened.

“The FBI has verified that none of these people called law enforcement to warn them about the shooting. The FBI database shows no advance tips from anyone that this shooting was about to happen.”
