Evidence missed

The Associated Press has an article at Philly.com about an ugly case:

The Florida sheriff's office that investigated the disappearance of Casey Anthony's two-year-old daughter, Caylee Anthony (photo), overlooked evidence that someone in their home did a Google search for "fool-proof" suffocation methods on the day the girl was last seen alive.
Orange County Sheriff's Captain Angelo Nieves said recently that the office's computer investigator missed the 16 June 2008, search. The agency's admission was first reported by Orlando television station WKMG; it's not known who performed the search. The station reported it was done on a browser primarily used by Caylee's mother, Casey Anthony, who was acquitted of the girl's murder in 2011.
Anthony's attorneys argued during trial that Casey Anthony helped her father, George Anthony, cover up the girl's drowning in the family pool.
WKMG reported that sheriff's investigators pulled seventeen vague entries from the computer's Internet Explorer browser, not the Mozilla Firefox browser commonly used by Casey Anthony. More than twelve hundred Firefox entries, including the suffocation search, were overlooked.
Whoever conducted the Google search looked for the term "fool-proof suffication", misspelling suffocation, then clicked on an article about suicide that discussed poison and putting a bag over one's head.
The browser then recorded activity on the social networking site MySpace, which was used by Casey Anthony but not her father.
A computer expert for Anthony s defense team found the search before the trial. Her lead attorney, Jose Baez, first mentioned the search in his book about the case but suggested it was George Anthony who conducted the search after Caylee drowned because he wanted to kill himself. Not knowing about the computer search, prosecutors had argued Caylee was poisoned with chloroform and then suffocated by duct tape placed over her mouth and nose. The girl's body was found six months after she disappeared in a field near the family home and was too decomposed for an exact cause of death to be determined.
Prosecutors presented evidence that someone in the Anthony home searched online for how to make chloroform, but Casey Anthony's mother, Cindy, testified that she had done the searches by mistake while seeking information on chlorophyll.
Many jurors apparently went into hiding amid public outrage over the verdict and refused to comment, but two have said prosecutors couldn't conclusively prove how Caylee died.
Prosecutors Linda Drane Burdick and Jeff Ashton didn't respond to emails from the Associated Press, but Ashton told WKMG that "it's just a shame we didn't have it. This certainly would have put the accidental death claim in serious question."

Rico says the Anthony's should show up, mysteriously drowned... (For full disclosure, Rico's ladyfriend has a two-year old granddaughter even cuter, if that's possible, than Caylee; anyone harming that child would face not only his ladyfriend's wrath, but Rico's as well. Drowning would look good by comparison...)
