He says they also seized guns and lots of drugs.
"Now think about 7,000 doses of heroin, fentanyl-cut cocaine, fentanyl-cut crystal meth and think about 7,000 potential deaths," Hogan said.
Among those arrested were a mother and son who've been charged in the death of one of their customers.
But Hogan says Chester County can't fight the scourge by itself.
"The problem is and remains a central dealing point. And that central dealing point, that central supply point is Philadelphia. And until Philadelphia cuts off that supply, then the entire region will keep going there. Because Philadelphia has the cheapest and purest heroin in the United States," he said.
Hogan says he has asked Philadelphia officials to consider creating a task force to address the drug problem.
Meanwhile, he says more resources going into treatment and education programs have been paying off.
