Minneapolis Police Chief Brian O'Hara told reporters that the shooter took his own life in the rear of Annunciation Catholic Church.

"Children are dead; there are families that have a deceased child; you cannot put into words the gravity, tragedy or absolute pain of the situation," Mayor Jacob Frey of Minneapolis said at the news conference. 

The New York Post is reporting that the shooter has been identified as "Robin Westman."

According to NYPost, Westman maintained a YouTube account that featured a video displaying multiple weapons.

One screenshot from the video showed a semi-automatic rifle and a shotgun, with text on one magazine reading "kill Donald Trump."

Benny Johnson confirmed: "Minneapolis Catholic church shooter Robin Westman was a transgender who "identified as a woman" and legally changed his name from "Robert" in 2020."
