William C. Anderson, 31, of Ingleside.

An Ingleside man who sold drugs laced with fentanyl, causing the death of a 45-year-old woman in 2018, was sentenced to six years in prison, court records show.

William C. Anderson, 31, of the 26100 block of West Lakeview Avenue in Ingleside, was indicted on seven counts of drug-induced homicide, a Class X felony, and three counts of unlawful delivery of a controlled substance.

The McHenry Police Department responded on August 31, 2018, to a call of a person found unresponsive.

Officers located 45-year-old Heather Crimaldi who was deceased from an apparent drug overdose, according to prosecutors. Items of drug paraphernalia consistent with heroin use were found near her body.

An autopsy showed that the Crimaldi, of Freeport, died as a result of a fentanyl and heroin overdose.

An investigation showed that Heather Crimaldi obtained the fentanyl-laced heroin from Christopher Crimaldi, according to court documents.

Anderson allegedly sold the drugs to Christopher Crimaldi just before Christopher provided the drugs to Heather.

Anderson has four prior drug convictions, two in Lake County and two in Cook County.

The McHenry County State’s Attorney’s Office reached a plea deal on Thursday with Anderson, who pleaded guilty to one count of drug-induced homicide.

In exchange, prosecutors dismissed all of his other charges. Anderson was sentenced to six years in the Illinois Department of Corrections.

He will also be required to pay $2,605 in court fees and fines. Anderson remains held in the McHenry County Jail awaiting transfer to a state prison.
