Joey Jordison was pronounced dead at the scene. However, no foul play is suspected and there were no illegal drugs found at the house. The medical examiner will now work to determine an official cause of death, according to TMZ.

Joey died in his sleep Monday, according to his family. The cause of death is unclear, but a statement from his loved ones says he passed away peacefully.

The family says Joey’s death “has left us with empty hearts and feelings of indescribable sorrow” and they’re remembering him as a prolific drummer, musician and artist with a quick wit, gentle personality and giant heart.

Jordison left Slipknot in 2013 and formed the band Scar The Martyr, also playing drums. He played guitar for the metal band Murderdolls and most recently was rocking out with the band Sinsaenum.

Over his career, Joey played with tons of heavy metal bands, like Rob Zombie, Korn, Metallica, Otep, Satyricon and Ministry.
