Casey L. Johann, 24, of Wheeling.

A woman has been sentenced to five years in prison after she violated her probation sentence in connection with the drug-induced homicide of a McHenry man.

Casey L. Johann, 24, of the 0-100 block of Curricle Road in Wheeling, and John M. Maly, 26, of the 2900 block of Wooded Lane in McHenry, were both charged in March 2021 with drug-induced homicide, a Class X felony.

A criminal complaint filed in McHenry County Circuit Court alleged that Johann and Maly delivered fentanyl, a controlled substance, to Tyler D. Martin on October 23, 2020.

Martin, 29, ingested the substance, causing his death, according to the complaint, which was filed by a McHenry County sheriff’s detective.

A motion filed by McHenry County Assistant State’s Attorney Ken Hudson said that Martin was found dead at his McHenry home on October 24, 2020, following the overdose.

Hudson said that Johann and Maly delivered the fentanyl to Martin the night before he was found dead.

John M. Maly, 26, of McHenry.

An autopsy confirmed that Martin died from the adverse effects of fentanyl. Court documents did not say how detectives linked Johann and Maly as the suspects.

Hudson said in the motion that Maly has four separate felony convictions dating back to 2015 for unlawful delivery of a controlled substance.

Court records show Johann pleaded guilty to a reduced charge of attempted drug-induced homicide, a Class 1 felony.

She was sentenced on September 9 to 30 months of felony probation and 250 hours of public service work.

According to a petition for revocation of probation filed by prosecutors, Johann tested positive for opiates on multiple occasions in December despite being barred from consuming illegal drugs.

Johann also failed to obtain a substance abuse evaluation within 30 days of her sentencing, the petition said.

McHenry County Judge Michael Coppedge on Tuesday resentenced Johann to five years in the Illinois Department of Corrections, court records show.

She will be required to serve the sentence at 50% and will receive 238 days of credit for time served.

Maly, who pleaded not guilty to his charges, remains held in the McHenry County Jail and a status hearing for a trial date is scheduled for May 5.
