Polina Dvorkina is a Russian radical feminist, that intended a mass shooting.

She bought a gun, her father gave her some money, the rest she earned at KFC. She changed her surname to Dvorkina, her original surname was Kechina.

She planned her crime, looked up for local kindergartens to chose one with the most boys. She pretended to seek a job and got an interview, did some recon to know the place better.

On 28 march of 2022 she shot her father and went to the kindergarten. Guards let her in. Heroic staff stopped her, before she could shoot any children.

Later she admitted that planned to kill all the boys.

Her trial started recently. I'll add links in comments
