Sadly an 18 year old Russian male shot and killed 20 people and injured another 70. This occurred last year on the 17th October, 2018. Kim and Mike (Youtubers) reported this today.
The Russian had been raised by his mother who is a Jehovah's Witness. His ex girlfriend said that he had been subject to bullying because he was seen as different by other school kids and believed the shooting may have been a form of revenge.

His mother belonged to the local Jehovah's Witnesses, limited his social activity, searched his pockets and refused to allow him to go to the cinema or use a computer, only allowing the latter when he turned 16. In the days before the attack he stated that he did not believe in the afterlife. On the eve of the attack, according to neighbors, Roslyakov burned a Bible in which he had highlighted verses.
