Steven C. Glennon, 59, of McHenry.

A McHenry man has been charged with drug-induced homicide for selling a fatal combination of fentanyl-laced heroin to a 27-year-old man.

Steven C. Glennon, 59, of the 3700 block of Millstream Street in McHenry, was charged with three counts of drug-induced homicide, a Class X felony, and three counts of unlawful delivery of a controlled substance, a Class 2 felony.

Alexander Ventresca, 27, died at his home in McHenry on November 26. The McHenry County Sheriff’s Office began an investigation into his death.

Detectives reviewed Ventresca’s phone records and they showed that he made efforts to obtain drugs during the morning and early afternoon of November 26, prosecutors said.

A criminal complaint filed in McHenry County Circuit Court alleges that Glennon sold Ventresca less than one gram of fentanyl and heroin mixture which ultimately led to the man’s death.

Ventresca traveled to Glennon’s apartment to obtain the drugs. Ventresca did not leave his house again after returning home from Glennon’s apartment and was found dead several hours later, prosecutors said.

At the time of the drug deal, Glennon was out of jail on bond following an unlawful possession of heroin charge, prosecutors said in court documents.

An arrest warrant was issued on March 27 for Glennon and police arrested him on May 7 and transported him to the McHenry County Jail.

He remains held on a $125,000 bond and is scheduled to appear in court on June 3.
