A woman who sold drugs at a Steak 'n Shake in St. Lucie County has been sentenced to 17 years in prison, according to a report at TCPalm.com.

Cybil Ballard Green, 43, was arrested in January as part of an investigation that launched last summer, according to the report. About 40 people were arrested in the probe — about 15 of them suspected drug dealers.

Assistant State Attorney David Dodd told the website that Green was a major player in the organization, saying that she "sort of was the entire supply chain."

Her charges included possessing and selling fentanyl, cocaine, carfentanil and marijuana. Heroin also was sold at the restaurant.

Like many Florida communities, St. Lucie County has seen opioid overdoses become an issue.

"I think that's the reason you see a sentence of so many years, because this stuff's killing people in St. Lucie County," Dodd told TCPalm.com.

He added: "What law enforcement found was not only was she essentially selling the heroin, fentanyl, and carfentanil but she was actually traveling down to West Palm where she was purchasing it, bringing it back into St. Lucie County, packaging it in individual capsules and then selling it," Dodd said.

Dodd said Green pleaded no contest to all charges and hoped the court would be lenient. Her prison sentence will be followed by 10 years of probation.

He said other major players in the organization are still awaiting trial, while some minor players have had their cases settled.
