Waupun Prisoner Death Labeled an Overdose

1/26/12 – A convicted killer died from an overdose of methadone while in his state prison cell, and officials are trying to find out how he got the drug. The Dodge County medical examiner’s office said yesterday that David Wapp’s death was caused by accident. The 31-year-old Wapp was found dead November eighth at the Waupun prison. And the only thing officials knew at the time was that foul play was not involved. Toxicology tests uncovered the overdose. Wapp, of the Mukwonago area, was sentenced in June of 2010 to life in prison with no chance for a supervised release. He stabbed and cut his ex-girlfriend, Samantha Peterson, 37 times while they argued in a car outside the home of Wapp’s aunt in Waukesha County. It happened four days after he left prison for another offense.
