WAUPUN, Wis. (WFRV) – Authorities in Fond du Lac County say a man was convicted of reckless homicide by a jury on Friday following a five-day trial in relation to an incident in May 2023.
According to a release from the Fond du Lac District Attorney’s Office, 27-year-old Dylan Mayne was found to be responsible for the death of one victim and the overdose of another.
In a criminal complaint obtained by Local Five, on May 17, 2023, officers from the Waupun Police Department responded at 6:13 p.m. to a home on Franklin Street in Waupun after a witness called and stated that the victim was dead and that it could be a drug-related incident.
Officials say they found the victim lying on his back in bed with a reddish foam blood trail from his mouth to his bed. The victim was then pronounced dead at the scene.
The complaint notes that the victim did have past contact with police due to drug-related incidents and a baggie was found under his body containing .9 grams of a white powdery substance that tested positive for fentanyl, codeine, heroin, morphine, and/or oxycodone.
Three other baggies weighing a combined 6.2 grams and containing a white powdery substance were also found at the scene, along with two Apple iPhones.
In the complaint, witnesses told authorities the victim had recently been in contact with Mayne and one other person who was believed to have overdosed and was med-flighted to a hospital in Madison earlier that morning.
Phone records and surveillance footage confirmed that Mayne had discussed and met up with the victim at 10:34 p.m. the night before the victim’s death to drop off the drugs.
The complaint states that the autopsy of the victim’s body revealed that he had alcohol, fentanyl, norfentanyl, and 4-ANPP in his system at the time of his death, with the cause of death confirmed to be “fentanyl toxicity.”
In August, authorities spoke with the person who overdosed on the same day that the victim died. During that time, they admitted to Mayne giving themselves the drugs they overdosed on and the victim the drugs that led to his death.
Mayne, who was in treatment when officials first attempted to make contact with him, was found and arrested on May 15, 2024, on charges of first-degree reckless Homicide.

Following the jury conviction on Friday, May 2, 2025, Fond du Lac District Attorney Eric Toney stated the following:
Too many families continue to suffer from the devastating effects of fentanyl and opioids, as we see fentanyl destroying families and communities. We will continue working with our federal, state, and local law enforcement partners to aggressively prosecute those that distribute poison into our communities. A conviction can’t bring a loved one back, but it might save someone else or spur another to seek treatment.
At this time, court records have not yet been updated to show when Mayne is expected to be back in court for sentencing.
