Slipknot on Paul Gray's doctor's charges: 'We want to make sure this man pays for what he has done' Get Tickets
Daniel Baldi has also been charged with the manslaughter of seven other people
Gray died of an accidental overdose in June 2010 and his doctor, Dr Daniel Baldi, is now set to face charges of involuntary manslaughter for allegedly prescribing high amounts of painkillers to people who later died.
The band have said that the news has "us all in a state of anger and sadness" and have said that they plan to do whatever they can to help the investigation.
They wrote: "As the loss of our brother Paul Gray is still very fresh for us in the Slipknot family, this new development has us all in a state of anger and sadness. The fact that this person took advantage of our brother’s illness while he was in a position to help others has outraged everyone in our family."
They continued: "We can only hope that justice will be served so this can never happen to anyone else ever again! Our thoughts go out to the families of the other victims. We plan to cooperate as much as we possibly can to ensure this tragedy is never repeated, and to make sure this man pays for what he has done."
If Baldi is convicted of all the charges, he could face up to 16 years in jail. His lawyer Guy Cook, has called the charges "unprecedented", telling the Des Moines Register: "It is unprecedented to turn unfortunate deaths or medical results into a crime against a doctor."
Slipknot have just completed a busy summer of touring and recently headlined their own 'Knotfest' events in Iowa.
