Police responded to a mass shooting at a Catholic school in Minneapolis, Minnesota, on Wednesday, where they said two children were killed and 17 people injured.

The suspected shooter of a group of Minneapolis Catholic school students at morning Mass Wednesday has been identified as Robert or Robin Westman, according to law enforcement sources.

He was carrying three firearms, according to authorities – a rifle, a pistol and a shotgun.

Court records show that a Minneapolis juvenile named Robert Westman had their name legally changed to Robin in 2019, and FBI Director Kash Patel confirmed that the shooter was born Robert and later identified as Robin.

Robin M. Westman was previously known as Robert Paul Westman, according to a court document filed by a mother named Mary Grace Westman.

“Minor child [redacted] identifies as a female and wants her name to reflect that identification,” she wrote at the time.

The name Mary Grace Westman also appeared on the school’s Facebook feed in 2021 – identified as the parish secretary ahead of her retirement party.

She could not immediately be reached for comment.

Disturbing videos posted by a person using the name Robin Westman were deleted from YouTube after the shooting, showing handwritten pages of a notebook, weapons with messages painted on them, and commentary from whoever filmed them.

Minneapolis Police Chief Brian O’Hara confirmed that police were “aware of a manifesto the shooter had timed to be released on YouTube.”

“[It] appeared to show him at the scene and included some disturbing writing,” the chief said.

He added that all three firearms used in the attack had been purchased legally by Westman, who had no prior criminal record.

Police were serving four search warrants – one at the crime scene and three more at residences in the Minneapolis metro area. Police seized additional guns from those residential locations, he said.

The attack took place at Annunciation Catholic School on Wednesday morning, but police have not identified any of the victims. They said two children were killed. Authorities said the shooter committed suicide after the act.

Ten victims were taken to Hennepen Healthcare, which said it had received one adult and six children in critical condition and another adult and two more children with injuries that were not considered life-threatening.

Three children were still receiving care at Children’s Minnesota while four other patients were discharged, the hospital told Fox News Digital.

“Our thoughts are with all the victims, their families and loved ones in our communities who are impacted by yet another senseless act of violence,” the hospital said in a statement. “We will not share more details to respect the privacy of our patients and families.”

Police said the attacker was a male dressed in black and carrying a black rifle.

The suspect’s relationship to the school is also unknown, and it has not been confirmed whether the suspect had any connection to any students or staff.

The Children’s Minnesota Hospital said six children are being treated after the shooting. The hospital would not share details about the patients out of respect for them and their loved ones.

Police said 17 people were injured, including 14 children. Two of the 17 people injured are in critical condition.

President Donald Trump and other federal and state leaders have already remarked on the shooting. Trump confirmed that the FBI has launched an investigation, which FBI Director Patel later said would investigate the shooting as both a hate crime and terrorism.

“The FBI is investigating this shooting as an act of domestic terrorism and hate crime targeting Catholics,” he announced in an X post.

Patel said two children died. They were 8 and 10 years old.
