Sheriff’s deputies in Green Bay plan to say more today (Thursday) about the arrest of a state lawmaker’s daughter for a recent drug death. Republican Assembly finance cochair John Nygren of Marinette cited his daughter Cassandra’s previous heroin problems in convincing lawmakers to approve close to two dozen bills in recent years to fight heroin and opioid addiction. Now, 28-year-old Cassandra Nygren of Green Bay and 33-year-old Shawn Gray, reportedly her fiancee, face possible charges for supplying the drugs that killed an undisclosed victim. Nygren is booked on possible counts of reckless homicide, delivering heroin, child neglect, and maintaining a drug trafficking place. She spent two years in prison for possessing illegal drugs in 2010 and was convicted again in 2015 for drug possession — and Gray has several drug convictions from the Appleton area.
