As the 10 year anniversary of Caylee Anthony‘s death approaches, Nancy Grace is speaking out about her “killer mom” Casey Anthony. The prosecutor turned TV personality wasted no time slamming Casey and basically saying what everyone is thinking about the tragic murder.

“If anyone fell for her act during the trial that Caylee was killed by accident in the pool and George [Anthony] fished her out I have news for them,” Nancy told Radar Online. “She gave an interview and said the last time she saw Caylee alive she was fine. She can’t keep her stories straight!” Casey was found not guilty of murder in 2011 by a Florida jury, but on her new show Grace vs. Abrams, also starring Dan Abrams, Nancy reveals that new details surrounding the case will be brought to light.

“The biggest bombshell was from an inmate who shared a cell with Casey,” she added. “They spent so much time together and she knew exactly what Casey said about Caylee’s death. If she had been brought to trial I believe there would have been a different verdict.”

Nancy also admits that Caylee reminds her of her 10-year-old twins, John and Lucy, which is what makes the murder so much harder for her to accept. “I just keep seeing those big brown eyes that were the sweetest most helpless looking eyes,” Nancy explained. “Her face looked as if she was calling for help. It makes me think of the twins when they were two.”

In her most recent interview, Casey once again asserted that she was innocent of her daughter’s murder. “The last time I saw my daughter I believed she was alive and was going to be OK, and that’s what was told to me,” she told the Associated Press. “I don’t give a s–t about what anyone thinks about me, I never will. I’m OK with myself, I sleep pretty good at night.”

However, Nancy is not the only person who doesn’t believe Casey. Famed prosecutor Marcia Clark also believes she has discovered new evidence that will prove Casey is responsible for her daughter’s death. During the trial, the term “foolproof suffocation” was found on Casey’s computer — and while the defense blamed her father, Marcia claims that is impossible.

“The program that the defense attorney’s expert used was incorrect as to the time stamp. And that it wasn’t 1:51 when the search was done, it was 2:51 — at which point we know based on cell phone pings that George Anthony was at work, he was not at home,” she said. “And that the only person who was at home when ‘foolproof suffocation’ was searched for was Casey Anthony. A pretty big deal.” Unfortunately for Nancy and Marcia, Casey can’t be retried for the murder.

Grace vs. Abrams airs on A&E on Thursdays at 11 p.m.
