He fell off a swing at age four. Then he killed 63 people and tracked them on a chessboard.

Sasha was four when the swing hit him in the head.

After that, his behavior completely changed.

He became aggressive. Emotionally unstable.

By eighteen he was drinking heavily.

And idolizing the Rostov Ripper, a killer with 50+ victims.

Sasha wanted to break the record.

His target: 64 kills. One for each square on a chessboard.

He asked a friend to help him.

The friend agreed. Then backed out.

So Sasha strangled him in a park with a rope.

Dumped the body in a sewer.

Square one.

Police questioned him. Found nothing.

He stayed quiet for nine years.

Then in 2001, the urge returned.

He befriended a man in the same park.

Played chess with him. Shared vodka.

Then beat him to death with the vodka bottle.

Dumped him in the sewer.

Then he did it again. And again.

By the end of 2001, eleven crosses filled his chessboard. Each one a human life.
