(Iron Ridge) An Iron Ridge man was sentenced Thursday to four years in prison for his role in a fatal opioid overdose. In February, Timothy Sedlmeier entered a no contest plea to a reduced felony count of Second Degree Reckless Homicide in the October 2017 death of Samantha Mattila. Sedlmeier says he found the 19-year-old slumped over the bathtub. Heroin that he put in a drawer for himself was missing. The 30-year-old told investigators that he bought the heroin that she used but did not supply it to her. Toxicology tests later confirmed that Mattila died of the synthetic opioid Fentanyl. In addition to prison, Sedlmeier was placed on extended supervision for seven years.
