Police are responding to a mass shooting at a Catholic school in Minneapolis, Minnesota on Wednesday, with reports of two children 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.

The sources said the shooter may have used both names. 

Court records show that a Minneapolis juvenile named Robert Westman had their name legally changed to Robin in 2019.

Robin M. Westman was previously known as Robert Paul Westman, according to 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. The clips' authenticity has not been confirmed by authorities.

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. 

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.

The Minneapolis Police Department shared a message from the city of Minneapolis confirming "there is no active threat to the community at this time," and "the shooter is contained."

The parents of a seven-month-old boy who has been missing for nearly two weeks in Southern California have been charged with his murder.

Jake Haro, 32, and his wife, Rebecca Haro, 41, were each charged with felony murder with malice on Tuesday in the death of their son Emmanuel, according to the Riverside County District Attorney’s office. They were also charged with filing a false police report, which is a misdemeanor. 

The Haros initially reported that their son had been kidnapped on Aug. 14, though investigators later determined that did not happen. Authorities believe the child is dead, though his remains have yet to be recovered as of Tuesday.

The couple appeared in court on Tuesday with their public defenders, but their arraignment was delayed until Sept. 4. Each was being held on $1 million bond, according to online jail records.

Riverside County prosecutors said they would not release additional information until a press conference on Wednesday.

Emmanuel was reported missing on Aug. 14. His mother told investigators that she had been attacked while changing Emmanuel's diaper in the parking lot of a store in the San Bernardino County community of Yucaipa, authorities said. She claimed that someone said "Hola" to her, after which everything "went blank."

"I woke up on the floor, and my son was gone," she said in an interview last week with FOX Los Angeles. 

The couple spoke to news outlets, making pleas to the public to help find their son.

MOTHER'S STORY QUESTIONED BY AUTHORITIES AS 7-MONTH-OLD REMAINS MISSING AFTER ALLEGED KIDNAPPING

Over the weekend, investigators said the couple had stopped cooperating, adding that there were "inconsistencies" in the mother's story. Investigators declined to discuss what these inconsistencies were.

On Friday, the Haros were taken into custody on suspicion of murder at their home in Cabazon, 90 miles east of Los Angeles. 

Authorities searched the family's home, and over the weekend they searched for the boy's body near a freeway while his father, wearing a jail jumpsuit, was present. The San Bernardino County Sheriff's Department said it wouldn't describe Jake Haro's presence during the search as "providing assistance," but declined to elaborate.

Jake Haro previously pleaded guilty to child cruelty charges in Riverside County in a separate case in 2018, Fox Los Angeles reported. At the time of Friday's arrest, he was on probation after he was convicted of those charges and jailed in 2023. 

Rebecca Haro told Southern California’s Press-Enterprise in a jailhouse interview last weekend that her husband wouldn't hurt an infant, and that she wanted to find her son.

"I want to be out looking for my baby," she said. "I will not give up. I will not give up on my baby."
