According to local news site BNO News the suspect had live-streamed footage of the attack on social media.
The person in the video identified themselves as an 18-year-old white male who was a “white supremacist, racist and anti-semite”.
A rambling, 106-page “manifesto” was posted online by the suspect in which he attempted to justify the killings.
And the WIVB article immediately starts talking about white supremacy and the possibility of a manifesto.
