Jermaine Jackson came out swinging at an event at the Magic Johnson theater in L.A. yesterday, claiming the 1993 molestation accusations against his brother were false ... and the suicide of the accuser's dad proves it.
Jermaine -- who spoke at a Michael Jackson charity event -- said the accuser's dad could not live with a guilty conscience and that's why he killed himself. Jermaine also latched onto Internet rumors that the accuser himself said Jackson didn't touch him.
Michael Jackson settled the '93 case by anteing up $20 million.
FYI -- the MJ stuff happens around 2:15 into the clip.
