‘Chessboard killer’ liked to 'stare death in the face'
During his testimony Pichushkin described how he ticked his victims off a list: first using a calendar, and then, as the numbers grew, a chessboard.
He said he liked to watch as his victims died, explaining this is why he gave up his initial practice of throwing them down a well.
The trial was adjourned after Pichushkin complained of stress.
He will testify on the last seven murder cases on Tuesday, before the jury leaves to decide on a verdict.
