(Iron Ridge) An Iron Ridge man accused of contributing to a fatal opioid overdose made his initial appearance in court Monday. Timothy Sedlmeier is facing a felony count of First Degree Reckless Homicide in the October 2017 death of a Waupun teen. According to the criminal complaint, the 28-year-old had known the victim, Samantha Mattila, for approximately one year. They had spent the days leading up to her death together, reportedly snorting heroin. Sedlmeier says he fell asleep on the couch the night she died and when he woke up, he found the 19-year-old slumped over the bathtub. The heroin that he put in a drawer for himself, he said, was gone. He assumed she had taken it. He allegedly 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, which is said to be up to 200 times as potent as morphine and is responsible for scores of deaths nationwide. If convicted, Sedlmeier is facing a maximum prison sentence of 40 years. Signature bond was set at $5,000 and a judge will decide next month if there is enough evidence to order a trial.
