(Watertown) A Watertown man was sentenced to 20 years in prison for supplying the drugs that caused an overdose death. Terence Jannke was in court for his sentencing hearing Monday after he was convicted by jury in October on felony charges of First Degree Reckless Homicide, Maintaining a Drug Trafficking Place as a Party to a Crime, and Possession with Intent to Deliver Heroin. The 50-year-old provided the drugs that killed Holly Nehls in May of 2016. Jannke’s role in the overdose came to light following the surprise confession of Gabriel Brandl who was sentenced to seven years in prison last January. Brandl said Nehls was initially fine after shooting up but then went unconscious. Brandl drove around for three hours deciding the right thing to do. Nehls eventually died and Jannke was implicated a short time later along with his roommate, 35-year-old Jason Twaite, who is charged with felony Maintaining a Drug Trafficking Place as a Party to a Crime. Twaite was placed on probation for two years in connection with the overdose death. A search warrant was executed at Jannke and Twaite’s residence, after tips from multiple confidential informants. Police found syringes, heroin packaging, and a drug ledger in Jannke’s bedroom. Jannke and Twaite were arrested soon after the search. At sentencing, District Attorney Kurt Klomberg said (quote) “Jannke has a history of selling drugs going back 25 years. Even after his heroin killed a person, he continued to sell drugs to others.” When released, Jannke will be placed on extended supervision for ten years.
