the florida sheriff's office now admitting it overlooked a computer search, one that everyone agrees could have been crucial to the prosecution. police say their investigator missed an internet search for foolproof suffocation methods. the search was done by someone in the anthony home on june 16th, 2008. that's the last day 2-year-old caylee anthony was seen alive. the bombshell is of course rising lots of questions. who did the search? why didn't the evidence get to prosecutors? the burning question, could the evidence have changed the verdict in former lapd detective mark fuhrman joining us. good evening, sir. >> good evening, greta. >> greta: i can't imagine anything more damming than that computer search on the last day the child was seen. i'm curious, how does this get overlooked? >> i have no idea. you would think, you have a child that's missing, whether she's kidnapped or you suspect she's been murdered, she is missing on a certain day, and that's where it should start,
