Slipknot bassist's autopsy 'inconclusive'

Slipknot bassist Paul Gray's cause of death is still unknown after an autopsy performed on Tuesday was found to be inconclusive.

Authorities say there will be a four to six-week wait for the results of toxicology tests, reports The AP.

Gray's wife, who is currently pregnant, said at a press conference that their daughter will grow up with the knowledge that her father was an "amazing person".

The 38-year-old was found dead in an Iowa hotel room early on Monday morning.
