Chester Bennington's suicide was a shock to bandmates, because the group had plans for a photo shoot in Hollywood just hours after the Linkin Park singer was found hanging at his home.
Multiple sources tell us ... Chester hanged himself in his bedroom. His body was discovered shortly before 9 AM PT Thursday by a housekeeper.
We're told Chester arrived back in L.A. Wednesday from Arizona, where he and his wife were spending time. She stayed in AZ, but his return suggests the singer took his life Wednesday night or early Thursday morning.
Our sources say one of his bandmates showed up at Chester's Palos Verdes Estates home shortly after police arrived. He said he was driving Chester to the photo shoot and was "absolutely shocked."
The band also has plans to tour in 1 week, which made the suicide all the more shocking.
TMZ broke the story of Chester's suicide, and that he was profoundly affected by the suicide by hanging of his close friend, Chris Cornell. By the way, today would have been Cornell's 53rd birthday.
