Melissa Rivers continues to honor her late mother with sweet throwback photos.
The TV personality posted an adorable Halloween pic with mom Joan Rivers at a charity event in 2004. "#TBT Tricks and treats! With mom at the Dream #Halloween Fundraiser for Children Affected by AIDS Foundation in 2004," she shared on her WhoSay page.
Just last week, the 46-year-old posted another #TBT of Joan playing in the yard with her grandson, Cooper. The legendary comedienne wears a black tee and denim jeans as she pushes little Coop on a tree swing. "Connecticut, 2004. Mom + Cooper = BFFs... A perfect day. #TBT," Melissa wrote.
The New York City Office of Chief Medical Examiner attributed Joan's death on Sept. 4 to a "therapeutic complication," with the exact cause being "anoxic encephalopathy due to hypoxic arrest during laryngoscopy and upper gastrointestinal endoscopy with propofol sedation for evaluation of voice changes and gastroesophageal reflux disease."
E! News has learned that Melissa is in the early stages of pursuing a wrongful death suit against the persons and entities that may be responsible for her mother's death.
"For Melissa, this is about getting an answer about why this happened and making sure it never happens again," a source confirms. "The only way to get these answers is to file a lawsuit. Melissa wants answers—not money."
