The Gameboy murder is investigated by Sky Crime

This week the resident psychologists and criminologists of Britain’s Most Evil Killers examine a gruesome murder that all starts with a Gameboy game.

Matthew Pyke was a student who lived with his girlfriend Joanna Witton in Nottingham. The couple were fans of the Nintendo strategy game Advance Wars and helped run a fansite based around it. It was there where 21-year-old German David Heiss developed an infatuation with Witton and began to obsessively stalk her.

Heiss spent many months travelling to and from the UK on a number of occasions to get up close to Joanna Witton, a number of visits were innocently welcomed by the couple, with on one occasion Heiss staying over at the couple’s flat when he was unable to secure hotel accommodation. However on his last visit, he forced his way into Pyke and Witton’s flat and stabbed him 86 times, leaving the body for Witton to find later.

Heiss was arrested at his home in Limburg on 24th September 2008, and in May 2009 he was sentenced to a minimum of 18 years in prison. Was it pure jealousy that drove him to commit such a vicious attack?
