(FOX 2) - There are new developments involving tainted steroid injections that led to a fungal meningitis outbreak in 20 states, including Michigan.
Pharmacist Glenn Chin and New England Compounding Center executive Barry Cadden have been formally charged with second-degree murder in Livingston County.
Both men are already serving time in federal prison on convictions of racketeering and fraud.
Back in 2012, more than 700 patients contracted meningitis infections after receiving contaminated steroid injections that came from the center.
Seventy-six patients from across the nation died, including many in Michigan.
Cadden and Chin are set to appear in a Livingston County courtroom March 5.
