Dimitros Vakrinos

In a case of insults leading to serial mayhem, Greek serial killer Dimitris Vakrinos claimed he murdered his victims after they made fun of his height. Standing at five feet four inches, Dimitris, 35, proved to be a powerhouse killer after confessing to committing — over a decade — five murders, six attempted murders, one attempted rape, four armed robberies and one attempted armed robbery. Arrested on April 9, 1997, the former taxi driver committed suicide while awaiting trial on May 12. He was found by a prison guard in the showers of the prison’s isolation ward hanging by the neck from shoelaces tied to a shower head.
