he took his life on Chris Cornell's birthdate. they became close friends over the years and i'm sure the date was a significant trigger. i also know that Scott Weiland passing 1.5 years ago or so weighed heavily on him. he looked up to Weiland and got to live a dream and sing for STP for awhile. i had some friends who were down in the dumps with this loss. thank u and RIP Chester Be.
