A city man who prosecutors allege “poisoned our community” with heroin for years will spend up to 24 years in state prison.

Jeroyd Conyers, 37, was sentenced Tuesday on five drug convictions, including one that involved a gun, by Butler County Judge Timothy McCune. In addition to the 12- to 24-year prison sentence, Conyers was ordered to pay nearly $100,000 in fines.

According to court records, Conyers’ arrest was part of a yearlong investigation by county narcotics officers. Investigators believe Conyers helped funnel heroin to Butler from his hometown of Chicago on a regular basis.

Conyers pleaded guilty to two counts of possession with intent to deliver, two counts of delivering heroin, and a count each of delivery of a controlled substance, and former convict not to possess a weapon.
