Glen Ellyn Man Gets 7 Years For Drug Induced Homicide In Clarendon Hills Woman's Death

WHEATON – A Glen Ellyn man was sentenced Friday morning in a DuPage County courtroom for a supplying afatal dose of fentanyl to his girlfriend. Sergius Harty, 32, appeared before Judge Mia McPherson, who handed down a seven-year sentence in the Illinois Department of Corrections.

Harty pleaded guilty June 10 to one count of drug induced homicide, a Class X felony, for his role in the 2021 overdose death of his girlfriend, 29-year-old Margaret McCabe, of unincorporated Clarendon Hills.

On Nov. 5, 2021,DuPage County Sheriff’s Police responded to a call of an unresponsive female, later identified as McCabe, in unincorporated Clarendon Hills. A family member had placed the call. McCabe was immediately transported to a local hospital, where she was pronounced deceased.

An investigation into McCabe’s death revealed that she had died of fentanyl intoxication, police said. During the course of their investigation, investigators reportedly learned that McCabe had gone with Harty the day before to Oak Park to purchase drugs.

Shortly after Harty purchased several bags of narcotics, authorities said he gave one bag containing fentanyl to McCabe. At home the next day, McCabe ingested the fentanyl given to her by Harty and died.

Harty was taken in custody Aug. 18, 2022 on an arrest warrant and charged with drug induced homicide. He appeared in bond court the next day, where bail was set a $500,000. The next month, Harty posted a 10-percent bond and was released from the sheriff’s custody on GPS electronic monitoring.

“While we have made progress in getting drug users the help they need, those who supply the drugs are an entirely different concern,” DuPage County State’s Attorney Robert Berlin said in a statement. “A dealer, a friend, or even a family member may have second thoughts about supplying this poison knowing that they will be looking at a significant amount of time behind bars if they are proved to be the source of a fatal overdose …”

Berlin also thanked Sheriff James Mendrick and his officers, and Assistant State’s Attorneys Adam Frahm and Sara Henley, for their holding Harty responsible for the death of Margaret McCabe.

Harty will be required to serve 75 percent of his sentence before being eligible for parole.
