A warrant carrying a $500,000 bond has been issued for a woman who allegedly sold fentanyl-laced drugs to a 39-year-old man in Marengo, causing his overdose death.

The Marengo Police Department and Marengo Fire and Rescue Districts were called around 12:40 a.m. on July 16 to the 900 block of Beaver Pond Drive in Marengo.

Marengo Police Department Sgt. Andrew Kjellgren said officers received a call of an unresponsive man at the home.

Police and fire personnel located Michael Mancuso, 39, of Marengo, inside the residence.

Mancuso was pronounced dead at the scene, Kjellgren said.

The McHenry County Coroner’s office completed an autopsy and it was learned that Mancuso died as a result of a lethal dose of controlled substances, including fentanyl.

An investigation was conducted and police obtained an arrest warrant for Melissa M. Ryan, 36, of Marengo.

Ryan was charged with drug-induced homicide, a Class X felony, unlawful delivery of a controlled substance, a Class 2 felony and unlawful possession of a controlled substance, a Class 4 felony.

A judge set bond on the warrant at $500,000, meaning she would need to post $50,000 cash to be released once she is in custody.

Court documents allege Ryan delivered the drugs to Mancuso hours before his death.

An arrest warrant was also obtained for Paul Moser, 62, of Marengo, for two counts of concealing or aiding a fugitive, a Class 4 felony.

Moser was arrested Saturday by the Marengo Police Department.

Ryan has not been located yet, Kjellgren said.

Anyone with knowledge of her whereabouts is asked to call their local police department.
