In July 2023, items were seized from Preisler's home in Green Bay, leading to charges of multiple drug manufacturing and delivery counts. Since then, he has faced additional charges including drug possession and bail jumping. In January 2025, Preisler was convicted of two bail jumping charges for using drugs, which he claimed were to cope with pain issues. He was originally placed on probation and ordered to serve six months in jail.
