Two young children were killed and 17 others were injured in a shooting during a Catholic Mass packed with young students in Minneapolis. The shooter who carried out the mass shooting Minneapolis Catholic school's church has been identified as a 23-year-old transgender woman Robin Westman whose mom used to work at the school and who harbored a disdain for President Donald Trump, reports Daily Mail.

Westman's mother Mary Grace Westman, once reportedly employed at the school, according to local station KARE 11. She is now retired, according to an old Facebook post. Robin Westman shot through stained glass windows at children sitting praying on the pews inside Annunciation Catholic School's church at about 8.30am local time Wednesday, triggering panic at the school.

Westman, a transgender woman who changed her name from Robert in 2019, was armed with three guns - a rifle, a shotgun and a pistol, police said. Westman fired all three weapons, which police said were purchased legally, during the attack. Westman fired a rifle through the windows of the Catholic church where students were celebrating their first Mass of the new school year on Wednesday morning, killing an 8 and a 10-year-old sitting in the pews.

Robin Westman did not have a criminal history and the motive remains a mystery, several police sources told media outlets. However, a chilling video shared on a now-deleted YouTube account appears to reveal the killer's sick manifesto.

Investigators are now examining a disturbing digital trail believed to have been left by Westman prior to the attack. A now-deleted YouTube video reportedly belonging to Westman showed a 20-minute manifesto uploaded just hours before the deadly shooting.

US reports indicate that police are closely analyzing this footage, which included a drawing of the school’s church being repeatedly stabbed by a man while the suspect muttered, “I’m going to kill myself.”

The 20-minute-long video showed Robin showing off her kill kit of ammunition, magazines and firearms and revealed her twisted obsession with other school shooters, dislike of Trump and mockery of the church. Westman also showed the camera pages of handwritten notes in a final letter to her family and friends.

In the letter, Westman said she believed she had cancer caused by a vaping habit.

"I think I am dying of cancer. It's a tragic end as it's entirely self inflicted. I did this to myself as I cannot control myself and have been destroying my body through vaping and other means," the shooter wrote.

Westman went on to write that she wanted "to go out on my own means". "Unfortunately, due to my depression, anger and twisted mid, I want to fulfill a final act that has been in the back of my head for years," Westman wrote.

Another video allegedly posted by the shooter displayed the phrases “kill Donald Trump” and “for the children” written on gun magazines, while additional clips on the same channel showed images of a semi-automatic rifle and a shotgun. Police also confirmed that Westman had parked his vehicle near the school, and it is now part of the ongoing investigation. One of the cartridges bore a chilling inscription: “For the children.”

Scrawled across his stockpile of magazines and weapons were disturbing notes laced with rage — mocking religion and voicing violent hatred toward Donald Trump. Messages like “Take this all of you, and eat!”, “Do you believe in God?” and “Where is your God?” targeted the church, while another simply read: “Kill Donald Trump.”

Some of the ramblings were even written in Russian, adding another layer of mystery to his state of mind. In the footage, massive wooden planks were also shown, each marked with the ominous words: “No escape.” Hennepin Healthcare, the main trauma hospital in Minneapolis, said in a statement that they received 10 patients, including eight children — aged 6 through 14 — and two adults. Seven were considered to be in critical condition. The hospital previously said it had received 11 patients.

Children’s Minnesota, a pediatric trauma hospital, said it admitted seven children ages 9 through 16. Minnesota Gov. Tim Walz posted on X: “Minnesota is heartbroken. From the officers responding, to the clergy and teachers providing comfort, to the hospital staff saving lives, we will get through this together. Hug your kids close."
