WILMINGTON – Police said two men were selling hundreds of hits of heroin each week before their arrest Wednesday.

For the last several months, Larry Mikesh, 52, and Jason D. Gregory, 40, would travel to Chicago every two or three days and return with a supply to sell in the Wilmington area, Police Chief Phillip Arnold said Thursday.

“They’d come to our attention [because of] several different cases, and we reached out to a Drug Enforcement Administration task force,” Arnold said. “The task force brought in 15 guys. It gave us resources we just wouldn’t have otherwise.”

Shortly after noon Wednesday, police raided the duplex in the 30700 block of Southwest Frontage Road where Mikesh and Gregory reside. Police found about 16 grams of heroin, 6 grams of marijuana, and scales and packaging material inside, Arnold said.

“According to several informants, as well as the admission of the two subjects arrested during the raid, they are possibly the largest suppliers of heroin to the immediate area,” a department news release stated. “After their arrest, the two admitted to selling more than 400 hits of heroin per week.”

Mikesh and Gregory were arrested on charges of delivery of drugs and booked into the Will County jail. Mikesh’s sister also was living at the residence, but was not charged, Arnold said.

According to Will County court records, Mikesh was living in Cicero in 1994 when Bolingbrook police cited him with disorderly conduct. Gregory has a substantial number of traffic charges on his criminal record. He also was convicted of theft after using someone else’s credit card at a store in Joliet in 2012.

“We have not had previous reports regarding that address, but when some trucks were broken into at the [nearby] concrete plant last year, officers did question if they’d heard or seen anything,” Arnold said.
