The story behind the death of "Real Housewives of Beverly Hills'" Russell Armstrong three weeks ago may not be over yet.
Armstrong's sister Laurie Kelsoe told TODAY's Miguel Almaguer that she has doubts about whether his death, which has been ruled a suicide, wasn't actually something else.
"From the minute that I got the call, I knew that it was not suicide," Kelsoe said, adding that her brother would not have left his children behind, regardless of the trouble he was in.
"I don't know if it was something in the marriage, I don't know if it was his business, or the show, I don't know," she said, visibly upset in the taped interview.
Kelsoe said she was planning to visit him the day before he died. "I wish I had gone," she sobbed.
The coroner's report says there was "no sign of foul play" in the death.
TMZ reported that Armstrong's family is planning to hire a private investigator to look into his death, which Almaguer confirmed in his story. But at this time, he noted, the Los Angeles Police Department has no new information that would lead them to re-open the case.
"Real Housewives of Beverly Hills" premiered on Sept. 5 with a special segment addressing Armstrong's death prior to the show's actual start. According to The Hollywood Reporter, the combination led to a major ratings boost, providing the franchise's biggest series premiere ever, with 2.2 million people watching -- a 42% overall increase from last fall's series premiere.
