Leonid Greyser is not released yet for the murder of Ariada Korol.

The Ariada Korol murderer is still behind the bars serving his sentence.

He was sentenced to compulsory psychiatric medical treatment by the Shcherbinsky District Court in Moscow in 2020.

It is reported that his sentence is reviewed every six months of his medical examination.

However, Russian law prevents the public from getting any further information on his verdict, reports Lad Bible.

The incident took place in 2019 when the brother-sister duo’s neighbors heard the ‘screamings’ of a woman.

After the police were called, Greyser had already undressed and drew demonic symbols with blood on his sister’s body and his head.

He was performing a ritual and asking Satan to be free from his body.

Greyser has shown no regrets on his actions and even tried to claim out of a ceiling in the middle of his court hearing.

The video of him trying to escape has gone viral on the web especially on TikTok.
