A transgender gunman who killed two children after opening fire during a Catholic school church service scrawled “Jew gas” and “for the children” on weapons used in the attack.

Robin Westman, formerly known as Robert, fired dozens of rounds of bullets through the stained glass windows of Annunciation Catholic Church in Minneapolis, Minnesota, where children from the adjacent school were attending a start-of-term Mass.

Westman applied to change his name to Robin by deed poll in documents seen by The Telegraph. In the deed poll request, his parents justified the name change by saying Westman “identifies as a female and wants her name to reflect that identification.”

The request was granted by Dakota country in January 2020.
