Musical equipment worth $36,000 has been stolen from the Iowa home of Slipknot / Stone Sour frontman Corey Taylor.

According to The Des Moines Register, the singer told police that two guitars that had belonged to the band’s bassist Paul Gray, who died in May 2010, were among the items stolen.

The Des Moines Register reports that Taylor told police that a friend stole the gear when he and his wife were on a month-long tour of Europe, from which they returned on July 6.  A friend told Taylor’s wife that she believed the suspect had been stealing musical equipment from the couple’s West Des Moines home and storage units, according to the report.

Another friend became suspicious when he heard the suspect asking to buy equipment back from a local guitar store, the report said.

A third friend was able to identify some of Taylor’s equipment at the guitar store, the report stated. The store’s manager is storing some of the stolen items and working to track down other equipment that was already sold.

Slipknot’s last album, All Hope Is Gone, was released in 2008 before the Gray’s death, and they have never confirmed that they will be recording another LP. But during their recent headline set at the Download festival, Corey Taylor told the crowd: “Don’t be surprised if you see us again real soon.”
