Authorities expect as many as two dozen people to be charged in connection to the largest heroin bust and seizure in Huntingdon County history.

At a joint press conference Friday morning, District Attorney George Zanic announced the arrest of Curtis Warren Koehler, accusing him of being the ringleader of a massive heroin operation, adding he is known by users as "Big Man."

"Mr. Koehler was essentially the CEO of the drug operation. He tended not to get his hands dirty. He used addicts, he used runners," said Zanic. "The Spell brothers were runners, were dealers for Mr. Koehler. We knew all about Mr. Koehler at the time that we took down the Spell brothers in September. In addition, he had many people working for him."

Zanic said Koehler's heroin business grossed as much as $90,000 a week.

Agents arrested Phillip, Kenneth, William and Thomas Spell during a raid at a home on Moore Street on Sept. 7.

In addition, authorities arrested James Sheffield, Jamie Lynn McCall, Adam Fye, Dusten Holland and Travis Park on suspicion of playing different roles in connection to the heroin ring.

Attorney General's Office Narcotics Supervisory Agent James Walstrom said as many as two dozen people are expected to be charged in connection to the operation, and more arrests are imminent.

"We know who is involved in this investigation. To the persons who we have not arrested yet: We know who you are, so if you are interested in talking to us, it would be in your best interest to do that before we come talk to you."

Community leaders told 6News that they came to the press conference to show their support for the latest efforts to wipe out the heroin addiction plaguing the Huntingdon area.

"The scary part of the whole situation is how much the borough was involved, as far as the drugs," said Borough Mayor Dee Dee Brown.

"We have a lot of children that will be affected by this entire investigation," said Borough Council Vice President Joan Cassatt. "I feel for the children."
