The police would not confirm that the victim died of a suicide, though the preliminary determination was an "apparent suicide", Mr. Freeman said. The group's debut album, "Ultramega OK", came a year later.
Cornell is considered one of the founding fathers of the Seattle grunge scene of the late 1980s and early 1990s, along with bands like Nirvana, Alice in Chains and Pearl Jam.
Later, Cornell and Soundgarden reunited and in 2012 released the band's sixth studio album, King Animal.
His death was unexpected and therefore shocking to all of his and the band's followers.
Cornell left the band in 2007 amid reports that he was unhappy with the financial arrangements.
Cornell, a former addict and alcoholic, became sober in 2002, and reflected on his journey with substances - and the journeys of his peers - in a 2015 interview with Rolling Stone.
Cornell also had an extensive solo career as a singer, guitarist, composer and lyricist and worked with various other musicians over three decades in the music business.
Around the time of his Timbaland produced album "Scream", Cornell covered the Michael Jackson song "Billie Jean" in an acoustic rendition that would garner him many accolades, and proved particularly powerful when Jackson died in June of 2009. It also was the first Bond film since Octopussy to have a different title than its film, the first from an American male singer and the first one not included on the movie soundtrack.
Before returning to Soundgarden, Cornell formed the band Audioslave in 2001 with three former members of Rage Against the Machine.
The band broke up in 1997 but later reformed.
Kiss singer Paul Stanley tweeted he was "Stunned to hear the death of Chris Cornell", while Aerosmith's Joe Perry called his passing "a sad loss of a great talent to the world".
In November 2016, Cornell hit the road for the first time with another supergroup of sorts, Temple of the Dog, which features a blend of members of Soundgarden and Pearl Jam.
The Soundgarden and Audioslave singer died suddenly after a show in Detroit, USA.
"I can tell you that he was a lovely, caring, generous and sweet friend, and he always acted like a big brother to me", The Promise producer Eric Esrailian told PEOPLE exclusively.
