Joosu Tomio Karppinen, 34, convicted of two murders in Jyväskylä, Finland, is due to appear before the Vaasa Court of Appeal. Karppinen was sentenced to life imprisonment for the murder of his father and his father’s wife. He is now seeking to have his conviction altered, arguing he was of diminished responsibility at the time of the crimes. The 34-year-old will present details regarding his mental state and the circumstances leading up to the killings. The Vaasa Court of Appeal will hear the case this Wednesday. Karppinen is requesting that he be found guilty of two counts of manslaughter committed under diminished responsibility, rather than murder. This appeal centers on his mental state during the commission of the crimes in Jyväskylä.
