This news outlet obtained the list of previous defendants from the U.S. Attorney’s Office. Olinger and Bigelow had the oldest case and were linked to another defendant, Waiman Yu.
Olinger, 40, of Dayton, was sentenced in January to 10 years for possessing with intent to distribute more than 500 grams or more of meth. Bigelow, 21, of Springfield, also was sentenced in January. She received four years in prison for interstate travel to promote an unlawful activity.

Yu, 39 of Trotwood, was sentenced in February to five years in prison for possessing with intent to distribute in excess of 100 grams of heroin.
Yu had been driving the Passat before Olinger and Bigelow were caught, according to court documents. A complaint said the DEA used a GPS tracking device on his Hyundai Elantra and found drugs in that car during a traffic stop.
Yu — who was once sentenced to six years for conspiracy to commit murder in Greene County — was suspected of being part of a large drug trafficking organization for nearly 20 years, according to a DEA agent.

The other older convictions/pleas:
• Richard H. Smith, 32 of Youngstown, was sentenced in April to 9.5 years for conspiring to distribute and to possess with intent to distribute 50 grams or more of meth. While in state prison, Smith directed Chasity Gillenwater to pick up drugs supplied by Olinger and deliver them to David Crabtree in Pike County to be sold, according to a sentencing memorandum.
• Crabtree, 26 of Piketon, was sentenced in April to 6 2/3 years for the same charge as Smith.
• Gillenwater, 26 of Beaver, was sentenced in April to four years for the same charge as Smith.
• Joshua Kirtley, 34 of Middletown, pleaded guilty June 1 to the same charge as Smith, a much lower charge that he originally faced. Court documents alleged Kirtley was selling meth from his Pearl Street address.

A complaint said Kirtley admitted to buying $100,000 worth of meth in California that was mailed back to Ohio and moving 40 pounds of meth and $1 million in six months. Kirtley is scheduled to be sentenced Aug. 24.
The recently unsealed indictment into the alleged meth ring included the seizure of the 140 pounds of meth, nearly 15.5 pounds of fentanyl, nearly 4.5 pounds of heroin, more than $130,000 in cash and a Bersa 9mm pistol, according to court documents.
Seven defendants were indicted and were led by Salvador “Listo” Ramirez. A DEA agent said last week that the Ramirez group is linked to a “Mexican transnational criminal organization” and is associated with a high-ranking member of a “violent, international gang.”
