A week after a crazed 23-year-old shot and killed two children and injured 18 more victims at a Catholic mass in Minneapolis, details about a chaotic personal life and a meticulously planned attack by a maniac who was “obsessed with the idea of killing children” have begun to unravel.
Robin Westman, formerly Robert Westman, committed the heinous act at the Annunciation Catholic Church the morning of Aug. 27 before committing suicide at the scene. As a child, Westman attended both the school and the church, which is located next door.
The years and months leading up to the unthinkable mass shooting appear fraught with chaos in the shooter’s personal life.

Aug. 16: Westman leaves job at RISE dispensary
According to the Minnesota Star Tribune, Westman left his job at a marijuana dispensary called RISE only 11 days before the shooting.
An unnamed coworker told the paper that he worked as a “personal care specialist” and worked with patients who were part of a state medical marijuana program.
That coworker cryptically said “recent events have been the catalyst for this thing he has been planning for a long time.”
RISE said in a statement that it was “deeply saddened” by the shooting, and offered condolences to the victims, their families and the community as a whole.
“We have been informed that the individual identified by authorities as the shooter was a former employee of our RISE Dispensary in Minnesota for several months this year,” the company said. This individual was not employed by the company at the time of the incident.”
The company said it is fully cooperating with investigators.

While the shooter’s exact motive remains unknown, Acting United States Attorney for the District of Minnesota Joe Thompson said hatred aimed at everyone played a significant role.
“The shooter expressed hate towards almost every group imaginable. The shooter expressed hate towards Black people. The shooter expressed hate towards Mexican people. The shooter expressed hate towards Christian people. The shooter expressed hate towards Jewish people,” Thompson continued. “In short, the shooter appeared to hate all of us. The shooter’s heart was full of hate. There appears to be only one group that the shooter didn’t hate. One group of people who the shooter admired. That group were the school shooters and mass murderers that are notorious in this country.”
The FBI is investigating the mass shooting as a hate crime.
Mary Grace Westman did not return a comment request.
