“This sentence reflects the severity of the defendant’s role in exacerbating the scourge of the opioid epidemic,” said Attorney General Dana Nessel. “Fentanyl use and overdose is a tragedy that devastates families across the state and my office will continue to hold accountable, to the fullest extent of the law, those who push this poison in our communities.”

Michigan State Police say McClarty provided drugs obtained from Rosen to the victim. McClarty agreed in her plea deal to testify against Rosen, and did so at Rosen’s preliminary examination in March.
