The Globe tabloid has a story claiming the sister of late Supremes star Florence Ballard wants to dig up the singer’s body to prove she was in fact murdered, and not the victim of a coronary artery thrombosis as an autopsy concluded.

Maxine has never accepted that official cause of death, which happened more than 30 years ago, according to the Globe. Ballard’s 65-year-old sibling believes she was murdered because she knew too much about some of the music industry’s biggest players and was plotting an expose’ about Motown when she died.

She tells the Globe: “[Florence] didn’t have a history of heart disease. There was this brown cereal-type substance (in her system) that was never identified. I believe she was killed because someone wanted to silence her… Florence had big plans for the future. I believe she was killed.”

The Globe points to an old interview the late soul star gave to the Detroit Free Press just before her death, when she admitted she feared for her life after suing Motown founder Berry Gordy for what she claimed was missing millions in royalty money.

She revealed, “I began to get scared. I don’t know why, I just had a fear.”
