The infamous Casey Anthony lives a completely different life now after she was acquitted in the murder of her two-year-old daughter Caylee Anthony. But even though she was once known as “one of the most hated women in America,” there is a small circle of people who still believe that Casey is innocent — including the former lead investigator on her defense team, Patrick J. McKenna.

But their relationship didn’t end after the trial was over. Casey is currently living with Patrick, and she’s even employed by him. In a series of interviews with the Associated Press — the first since her trial — Casey revealed that she works for Patrick on his current cases by providing social media searches and other investigative work.

Patrick is a high-profile investigator.

According to his LinkedIn page, Patrick has owned a private investigative business — Patrick McKenna, Investigations — since the mid-1980s. He lists famous celebrities on his client list — from John Lennon’s former wife Yoko Ono to Kennedy family member William Kennedy Smith, and O.J. Simpson.

He worked on the O.J. Simpson case and unearthed key evidence.

Patrick also served as an investigator on the 1995 murder trial for the death of O.J.'s ex-wife Nicole Brown Simpson and her friend Ron Goldman. He was the person who found audio tapes of a Los Angeles cop Mark Fuhrman on a racist rant — which helped weaken the prosecution against O.J., ABC News reported.

He pointed out the similarities between O.J. Simpson’s trial and Casey Anthony’s.

In 2011, Patrick helped Casey get acquitted of first-degree murder, aggravated manslaughter, and aggravated child abuse, which was a similar outcome to O.J.'s case.

"The media attention and absolute conviction by the public that Casey and O.J. were guilty early on, without any consideration of the evidence, was so intense in both cases," Patrick told ABC News.

He helped Casey Anthony start her photography business.

In 2016, Casey Anthony returned to the spotlight as she tried to start a new career as a photographer. She filed papers to register her business — Case Photography, LLC — in West Palm Beach, Florida which is where she currently lives in Patrick’s home. He was even spotted out with her, helping her while she took some practice shots with her camera, according to the Daily Mail.
