Chilling new video in Caylee Anthony case

(NECN/WFTV) - There is some disturbing new video connected to the murder case of Caylee Anthony. Until now, investigators and only a few others have seen this video. Private investigator Jim Hoover shot the video of the Anthonys' private investigator Dominic Casey on November 15th and November 16th of 2008. This was at the scene a month before Caylee's remains were found there -- and at a nearby abandoned house. At both locations, he was focused on groupings of concrete stones. This chilling video was given exclusively to WFTV. It shows Casey searching and ramming a metal rod into the ground at the crime scene mere feet away from where Caylee's remains were later found, and at a nearby house, where he also forcefully knifed open black trash bags. His colleague, private eye Jim Hoover, who shot this tape, would not allow WFTV to record the sound, but a reporter listened to the whole thing and clearly heard Casey say "it would be right here." Hoover says it was obvious to him that Casey was getting inside information on his cell phone even though Dominic told WFTV he was talking to his ill daughter at the time. Detectives from Orange County and the FBI are investigating the time and date stamps on this videotape and Casey's cell phone records. 22-year-old Casey Anthony is jailed and has been charged with first degree murder of her two-year-old daughter, Caylee. On December 11, 2008, skeletal remains of what appeared to be a young child were found. The Orange County Medical Examiner confirmed on December 19, 2008, that the human remains found close to the home of the family were those of Caylee Anthony.
