ORLANDO, Fla. -- A blockbuster development unfolded Wednesday in the Casey Anthony case. A private investigator, who worked with George and Cindy Anthony, just told Eyewitness News his partner knew where Caylee's body was and their search for it was on camera.

Kathi Belich interviewed Jim Hoover and his attorney Wednesday afternoon. Eyewitness News broke the story and continues to work the angle of the mystery videotape recorded by private investigators working for the Anthonys.

The videotape reportedly showed the location of Caylee's remains weeks before they were discovered and it could be evidence that helps link Casey to her daughter's death.

The private investigator gave his videotape to detectives Wednesday. The evidence appears to be key incriminating evidence against Casey Anthony in the murder of her daughter.
