A Massachusetts pharmacist was sentenced Friday in Michigan to 7 1/2 to 15 years prison for his role in a 2012 national meningitis outbreak that killed dozens of people.

Neither Glenn Chin nor relatives of the Michigan victims made statements at his sentencing in Livingston County Circuit Court in Howell, northwest of Detroit.

Chin supervised production at New England Compounding Center in Framingham, Massachusetts, which shipped steroids for pain relief to clinics across the country. Investigators said the lab was rife with mold and insects.

More than 700 people in 20 states were sickened with fungal meningitis or other debilitating illnesses, and dozens died, according to the U.S. Centers for Disease Control and Prevention.
