Teen Colorado school shooting suspect reportedly fixated on Columbine attack

Desmond Holly also expressed neo-Nazi views online before a shooting critically injuring two students, ADL says

A teenager suspected in a shooting attack at a suburban Denver high school that left two students in critical condition appeared fascinated with previous mass shootings including Columbine and expressed neo-Nazi views online, according to experts.

Since December, Desmond Holly, 16, had been active on an online forum where users watch videos of killings and violence, mixed in with content on white supremacism and antisemitism, the Anti-Defamation League's Center on Extremism said in a report.
