Jaynell J. Ross Pleads Guilty to Drug Induced Homicide

Patrick D. Kenneally, McHenry County State’s Attorney, announces that 38-year-old Jaynell J. Ross of Rockford, Illinois, pled guilty to the offense of Drug Induced Homicide. Ross faces a penalty of between six and 17 years in the Illinois Department of Corrections. Under Truth in Sentencing Guidelines, Ross must serve 75% of the sentence imposed. 

Additionally, Ross’ sentence will run consecutive to a six year sentence which he received on November 14, 2018 in Winnebago County, Illinois, for a violation of the Illinois Controlled Substances Act.

In July of 2017, Andrew Giblin of McHenry County was found deceased.  Giblin’s death was later determined to be as the result of the adverse effects of heroin and cocaine ingestion. An investigation into the death of Giblin was commenced by the Narcotics Unit of the Office of the McHenry County Sheriff.  Leads derived by the Sheriff’s department resulted in a multi-jurisdictional investigation where Jaynell Ross was subsequently identified as the person who delivered the drugs which caused Giblin’s death. The McHenry County Sheriff’s Office was assisted in the investigation by the Rockford Police Department.  As part of the multi-jurisdictional collaboration, undercover purchases of heroin were made from Ross resulting in criminal charges in Winnebago County for those acts.

The case was prosecuted by John T. Gibbons, Chief of the Criminal Division of the Office of the McHenry County State’s Attorney. The case was investigated by the McHenry County Sheriff’s Office.
