In DuPage County, justice has been served as Sergius Harty, a 32-year-old Glen Ellyn resident, has been sentenced to a term of seven and a half years in prison after pleading guilty to a charge of Drug Induced Homicide; this comes after supplying a fatal dose of fentanyl that led to the death of his girlfriend, according to a report by DuPage County State's Attorney's Office. Facing the consequences this morning during his sentencing hearing, Judge Mia McPherson imposed the prison term that Harty is mandated to serve, ensuring 75% of the time must pass before he can be considered for parole.

On the fateful day of November 5, 2021, local authorities responded to a distress call about an unresponsive woman named Margaret McCabe, who tragically never regained consciousness and succumbed to fentanyl intoxication after Harty, born December 1, 1992, provided her with narcotics they procured in Oak Park a day before her death and despite posting bail and being released on GPS monitoring, Harty's temporary freedom ceased when he was taken into custody on August 18, 2022, following a warrant tied to the case. The intricate wheels of justice caught up to Harty when his actions resulted in irreversible loss, and with the recent court proceedings, the depth of those actions' gravity has been judicially recognized.

DuPage County State's Attorney Robert Berlin, emphasizing the critical distinction between drug users and suppliers, highlighted the county's resolve to not only provide support to those battling addiction but also to ensure that suppliers face stringent repercussions, as cited by the DuPage County State's Attorney's Office. Berlin expressed, "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."

The unwavering efforts of Sheriff James Mendrick and his team, alongside Assistant State's Attorneys Adam Frahm and Sara Henley, were instrumental in delivering justice for Margaret McCabe and in the continued combat against the illegal narcotics plaguing the streets, these tireless warriors of the law enforce the societal covenant that we stand on, when one grieves, we all shoulder the weight of that grief, and when one errs, the system rises to the uppercase of accountability. Berlin further lauded their dedication to the case and the overarching battle against drug proliferation, and while the sentence marks the end of a somber chapter for all involved, it stands as a poignant warning to anyone entwined in the dangerous dance of drug distribution.
