A cause of death for the 28-year-old rocker is still not known as the autopsy results were inconclusive. The coroner's office ordered toxicology, microscopic and laboratory tests to help determine why Sullivan died. It may be weeks before a cause of death is known.

On Monday the band posted a message from Jimmy's family thanking fans for their support. Here is what they had to say: We would like to thank all of Jimmy's fans for the heartfelt comments that have been posted – it is comforting to know that his genius and antics were appreciated and that he was loved so much. Our hearts are broken – he was much too young to fall.
