The Orange Country Sheriff's Department found him dead at his home in his car and, while an investigation has been started, foul play is not suspected. The department's spokesperson, Gail Krause, speculated that Dorman may have been on his way to see his doctor.
The group followed with Ball which contained the hit Soul Experience and followed with 1971's Metamorphosis. The group broke up in mid-71.
Dorman and bandmate Reinhardt went on to form Captain Beyond with Rod Evans from Deep Purple and Bobby Caldwell from Johnny Winter's band. The band recorded two albums (Captain Beyond and Sufficiently Breathless) before breaking up in 1973. They reformed again in 1976, recording the album Dawn Explosion, but again split the next year.
Dorman returned to Iron Butterfly in 1977 where he has remained, save for a two-year lapse in the mid-80's, until his death.
