The deranged gunman who shot and killed two children and injured more than 20 others at a Catholic school in Minneapolis has finally been identified.

According to reports from local media outlets, the suspect was a transgender woman, as disturbing images were shown that had the terms: “Kill Donald Trump” written and ‘For the Children’ across gun magazines.

Robin Westman, who was formerly known as Robert Westman, opened fire through the stained glass windows of a church at the Annunciation Catholic School, where his mother used to work.

This was during a celebratory back-to-school Mass filled with kids at about 8:30 am on Wednesday. Just hours before the massacre, Westman posted a series of twisted videos on YouTube, which entailed a manifesto at the press conference.

In that 20 minute video, Westman flips through the disturbing handwritten manifesto and most of it was printed in Cyrillic.

In those deranged writings, he gleefully fantasized about being that scary, horrible monster standing over powerless children and reverently confessing admiration for the 2012 Sandy Hook massacre. In that video, Westman slowly turned the pages of the red notebook and that’s lying on top of what seems to be the schematic diagrams, one of them reading: Ruger Mark IV.
