9 years in prison for McHenry man who tried robbing store at knifepoint, sold drugs in fatal overdose

Steven C. Glennon, 60, of McHenry.

A 60-year-old man who robbed a convenience store near McHenry while armed with a butcher knife in 2019 and also delivered drugs in a fatal overdose has been sentenced to nine years in prison.

Steven C. Glennon, 60, of the 28400 block of North Highview Road in McHenry, was charged with one count of aggravated robbery while indicating a firearm, a Class 2 felony.

In a separate case, he 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.

Glennon accepted a plea deal in March from the McHenry County State’s Attorney’s Office where he pleaded guilty to a downgraded charge of attempted robbery and his more serious robbery charge was dismissed.

Glennon also pleaded guilty to unlawful delivery of a controlled substance and prosecutors dropped the rest of his drug charges.

He was arrested on May 7, 2020, after detectives identified him as the suspect who delivered drugs to a man that later overdosed.

Court records say that Alexander Ventresca, 27, died at his home in McHenry on November 26, 2019. 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, 2019, prosecutors said.

A criminal complaint alleges that Glennon sold Ventresca less than one gram of a 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.

In Glennon’s robbery case, he was accused of robbing Nezda’s Little Store, located at 502 Ringwood Road in unincorporated McHenry, on May 9, 2019.

The McHenry County Sheriff’s Office said at the time of the incident that a man with a butcher knife entered the store and tried robbing it.

They say he demanded money from the cash register and lottery machine at the front counter. No one was hurt during the incident.

McHenry County Judge Robert Wilbrandt sentenced Glennon to nine years in prison for both cases.

Glennon will serve the sentence at 50% and will undergo two years of mandatory supervised release after his release from the Illinois Department of Corrections.
