Casey Anthony detectives missed Google search

ORLANDO, Fla. — The Florida sheriff’s office that investigated the disappearance of Casey Anthony’s 2-year-old daughter 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 Sunday that the office’s computer investigator missed the June 16, 2008, search entry.

The agency’s admission was first reported by Orlando television station WKMG. It is not known who performed the search. The station reported it was done on a browser primarily used by the 2-year-old’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 reports that sheriff’s investigators pulled 17 vague entries only from the computer’s Internet Explorer browser, not the Mozilla Firefox browser commonly used by Casey Anthony.

Whoever conducted the Google search looked for the term ‘‘fool-proof suffication,’’ misspelling ‘‘suffocation,’’ and then clicked on an article about suicide that discussed taking 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 analyst 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.
