Antioch man sent to prison for heroin possession

A 33-year-old Antioch man convicted by a McHenry County jury for possessing heroin last year in Crystal Lake was sentenced Thursday to 6½ in prison.

Derek S. Schwantner also is required to serve one year of mandatory supervised release and pay about $2,900 in fines and fees. He will receive credit for 424 days in the county jail awaiting trial.

Schwantner was found guilty in August of possession with intent to deliver a controlled substance and possession of a controlled substance.

Additional charges were dismissed, including a count of unlawful possession of a controlled substance with intent to deliver between 15 and 100 grams of a substance containing fentanyl, according to court documents.

Had he been found guilty of the more serious charge, he would have faced up to 30 years in prison.
