Chris Cornell fans hold vigil outside Detroit concert venue

A statement from his publicist said his widow, Vicky Karayiannis Cornell, and the rest of the family "were shocked to learn of his sudden and unexpected passing" and thanked fans for "their continuous love and loyalty". But Cornell's family said that without toxicology test results completed they don't know what caused his death.

Cornell was found dead at MGM Grand Detroit on Wednesday night. An autopsy is being conducted Thursday and some information from it is expected to be released later in the day, Wayne County spokeswoman Lisa Croff said.

Soon after Soundgarden's concert ended, at 11:30 p.m., Cornell's bodyguard Martin Kirsten said he accompanied the singer to his hotel room to help fix his computer and give him two Ativan "which victim takes for anxiety", the police report states.

It is not yet known if fans will be given the opportunity to mourn Cornell's death at a special ceremony, although the family's attorney, Kirk Pasich, reveals "one or more public memorials will be considered". Aerosmith guitarist Joe Perry tweeted: "Very sad news about Chris Cornell today". It was Cornell's security personnel who ultimately broke down his hotel room's bathroom door and discovered the legendary Seattle grunge rocker unresponsive on the floor.

The group hit its commercial peak in 1994 with its breakout album, "Superunknown", which was nominated for a Grammy Award for best rock album. In addition to Soundgarden, Pointfest was to feature Stone Sour, Pierce the Veil, Greek Fire and other bands.

Project 86 have launched their cover of Soundgarden's "Fell On Black Days" in tribute to Chris Cornell.

Cornell's wife said it's possible the legendary singer-songwriter didn't know what he was doing, and drugs could've played a part in his demise. You can also text HELLO to 741-741 for free, 24-hour support from the Crisis Text Line.
