Hours after Wednesday’s shooting at a Minneapolis Catholic church and school left two children dead and 17 other people wounded, Minnesota officials identified the now-deceased gunman as 23-year-old Robin Westman, who has been identified as transgender.

The shooting occurred around 8:30 a.m. local time as a multitude of students gathered for an all-school Mass at Annunciation Church. The two children killed were aged 8 and 10. Among the injured victims were 14 children, ranging from ages 6 to 15, and three adults in their 80s. All wounded victims are expected to survive their various injuries.
