If there already wasn’t enough evidence pertaining to Casey Anthony murdering her daughter Caylee, a new investigation of Casey’s computer shows that the last day Caylee was seen by her grandparents was also the day the phrase “foolproof suffocation” was searched on Anthony’s family PC.

What’s even more disgusting than this new discovery is the fact that detectives didn’t find this piece of evidence before the month and a half trial last year.

TV network WKMG-TV has brought this new development to the public and claims that it could have easily changed the jury’s mind.

According to WKMG-TV, Anthony’s defense attorney Jose Baez says that he in fact knew about this potential threat and was waiting for it to be brought up during the trial. Baez told the network he was “shocked” when the evidence never came up.

WKMG’s timeline of the day Caylee was last seen shows that Casey was in her parents’ home – as confirmed by cell phone pings – when the search was typed in at 2:51pm (which was misspelled as ‘suffication’).

Prosecutors concluded that Caylee was killed by chloroform suffocation. We could really use that double jeopardy amendment right now.
