According to the Des Moines Register, physician Daniel Baldi has recently been charged with eight counts of involuntary manslaughter for allegedly prescribing large amounts of narcotic painkillers to patients who later died of overdoses. Now what exactly does that have to do with metal? Well as it turns out, one of the eight patients identified in court papers was Slipknot bassist Paul Gray.

Charging documents released during Baldi’s court hearing state that the doctor “did unintentionally cause the death of Paul Gray by the commission of an act likely to cause death or serious injury, to-wit, continually wrote high-dose prescription narcotics to a known drug addict from 12/27/2005 until his death.” Baldi, who helped run an Iowa Health System pain clinic near Iowa Lutheran Hospital, could face up to 16 years if convicted on all accounts.

All of this comes roughly two years since the Slipknot bassist was found dead in a hotel in Urbandale, IA. He left behind his wife Brenna and daughter October, while Slipknot have (slowly) been moving forward with touring. More on Baldi’s court case will likely develop soon.
