A jury in Columbia County Circuit Court has found a rural Poynette man guilty of mistreatment of animals and stalking.  Twenty-eight-year-old Trent L. Hebel had been accused of poisoning a four-year-old golden retriever who died in 2015.  Columbia County deputies were called to investigate suspicious food containers found in a fenced-in backyard in 2016.  One contained rat poison-tainted meat.  No sentencing date for Hebel has been set.
