ET has the latest in the potential case to be brought against Joan Rivers' doctors.
New York entertainment journalist David Caplan tells ET that a family source says that right now Joan's daughter Melissa "is not looking to take legal action until the New York State Department of Health Investigation is complete." Caplan added, "For right now a family source tells me that Melissa's mood has gone from grief to sheer anger."
"Anybody can sue, but proving a case is not so easy -- especially medical malpractice cases," said medical malpractice attorney Andrew Smiley. "We won't know if she has a real case until we really see what happened ... You have to remember: a bad result doesn't always equal malpractice."
Joan Rivers passed on September 4 at age 81, and the legend was on the minds of many at Wednesday night's America's Got Talent season finale.
"My heart goes out to Melissa," said Cyndi Lauper. "They were a great family."
"I miss everything about Joan Rivers," said Howie Mandel. "Joan Rivers is not only a shining light in the world of entertainment, she was a shining light in my own personal world."
Recently, Melissa Rivers spoke out for the first time since her mother's funeral a little over a week ago.
"As my son Cooper and I mourn the loss of my mother, we want to thank everyone for the beautiful cards and flowers conveying heartfelt messages and condolences, which continue to arrive from around the world and through social media," Melissa wrote on her WhoSay and tweeted. "My mother would have been overwhelmed by the scope and depth of the love that people have expressed for her. It is certainly helping to lift our spirits during this time."
She continued, "We are forever grateful for your kindness and support in continuing to honor my mother's legacy, and for remembering the joy and laughter that she brought to so many."
