The singer, who had spoken about struggling with drugs and alcohol for years, reportedly hanged himself. His body was discovered Thursday morning, according to TMZ's sources.
Bennington was close friends with fellow rocker Chris Cornell, who also committed suicide by hanging in May. Thursday would have been Cornell's 53rd birthday.
Linkin Park had a string of hits in the late 1990 and early 2000s. Bennington's screeching vocals were one of the band's trademarks.
