A Warren County pharmaceutical distributor, two of its former top officials and two pharmacists could face up to 20 years in prison after being charged by a federal grand jury in Cincinnati for distributing millions of pain pills.

Springboro-based Miami-Luken Inc. and the four individuals were indicted on conspiracy charges for providing hydrocodone and oxycodone pills to more than 200 pharmacies in Ohio, West Virginia, Indiana and Tennessee.

"They and other co-conspirators are alleged to have knowingly entered into an agreement to distribute ... outside the scope of professional practice and not for a legitimate medical purpose," said Benjamin Glassman, the U.S. Attorney for the Southern District of Ohio.

Those charged:

Anthony Rattini, 71, of Colorado Springs, Colorado, the former president of Miami-Luken.

James Barclay, 72, of Springboro, Ohio, the former compliance officer of Miami-Luken.

Devonna Miller-West, 49, of Oceana, West Virginia, a pharmacist who owned Westside Pharmacy in Oceana, West Virginia.

Samuel "Randy" Ballengee, 54, of Lovely, Kentucky, a pharmacist who owned Tug Valley Pharmacy in Williamson, Kentucky.

Federal agents arrested Rattini in Colorado, Miller-West in West Virginia and Ballengee in Kentucky Thursday morning. They will appear in Cincinnati at the end of July. An arrest warrant is still out for Barclay.

Miami-Luken is no longer operating, Glassman said, but it generated more than $173 million in consolidated sales per year, according to a press release from the Department of Justice. More than 70% of the profits came from wholesale drug-sale distribution.

From 2011 to 2015, Rattini, Barclay and Miami-Luken distributed more than 2.3 million oxycodone pills and 2.6 million hydrocodone pills to Westside Pharmacy in Oceana, West Virginia, a town of about 1,400 people, according to the indictment. .

The opioid wholesale distributor gave 120,000 painkillers to Tug Valley Pharmacy in Williamson, West Virginia, in its first month of working together. It also provided more than 6 million hydrocodone pills to the pharmacy between 2008 and 2011.

In that same time frame, Miami-Luken distributed more than 3.7 million hydrocodone pills to a pharmacy in Kermit, West Virginia, home to about 400 people.

"Today's indictment is about ... holding accountable anyone and everyone with criminal responsibility for the diversion of drugs" Glassman said.

He previously called the opioid epidemic "the public health and safety crisis of our lifetime" and did so again.

Miami-Luken also had its own subsidiary pharmacies, according to the indictment.

Glassman said the wholesaler treated those pharmacies differently, "tracking their annual sales and prescriptions, and ensuring that these pharmacies filled only a reasonable number of prescriptions

"When you have doctors who are acting as drug dealers and are running pill mills, they are culpable and should be prosecuted," Glassman said.
