Nearly seven years after Casey Anthony was found not guilty of murdering her daughter Caylee, prosecutor Marcia Clark claims there is new evidence against the disgraced mother. Marcia, who is known best for her work on the O.J. Simpson trial, believes Casey’s search history proves she was responsible for the death of her two-year-old little girl.

During the trial, it was revealed that the term “foolproof suffocation” was found on Casey’s computer, but the defense blamed it on her father George Anthony at the time. Well, according to Marcia, that is impossible. “We reinvestigate,” Clark reportedly said according to TheWrap. “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. And that the only person who was at home when ‘foolproof suffocation’ was searched for was Casey Anthony. A pretty big deal.”

What’s more is that the time the history was deleted would have been right when Casey was brought home from her first session being questions by police. The argument is that only the person searching something sketchy would think to delete it, so the suffocation search was likely not her father if she deleted it.

This finding came as Marcia was reviewing the book by Casey’s lawyer Jose Baez and shooting her upcoming A&E series Marcia Clark Investigates the First 48, which will premiere Thursday, March 29. “I’m guessing the prosecution would have loved to have this information,” Marcia added. “That’s what we uncovered.”

Last year, Casey, 31, gave her first interview since her highly publicized trial and continued to deny any involvement in her daughter’s murder. “I’m still not even certain as I stand here today about what happened,” she told the Associated Press. “Based off what was in the media, I understand the reasons people feel about me. I understand why people have the opinions that they do.

She continued, “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.” It looks like Marcia is trying to change that. Marcia Clark Investigates the First 48 premieres March 29 on A&E at 9 p.m..
