The father of Kim Porter's oldest child is suggesting she died under causes far more nefarious than pneumonia.

Back in November of 2018, a then-47-year-old Porter passed away suddenly in her home. According to her autopsy, the cause was lobar pneumonia, and the manner was certified as "natural." The coroner also determined that she had "no known medical history other than recent flu-like symptoms."

Much like the mysterious deaths of Brittany Murphy and her husband, Simon Monjack – which were also ruled to be caused by pneumonia – skepticism and uncertainly surrounded Kim's passing.

After all, she was young and seemingly healthy – just as Brittany and Simon were believed to be.

Porter dated and had one son with record producer Al B. Sure! (real name Albert Joseph Brown III) before her longterm and best-known relationship with Sean "Diddy" Combs, with whom she had three children.

While Sure! has never really accepted that the cause of his ex's death had to do with a lung infection, he's now suggesting Porter was "running" from something prior to her passing and that he encouraged her to call the FBI for help.
