The first suspects in a child’s disappearance are always family members, but detectives in the Casey Anthony case overlooked a precious bit of information. The detectives that worked the disappearance of Casey Anthony’s baby girl overlooked an in-home Google search that was an obvious hint someone in the house was the culprit.

Not many people look for “fool-proof suffocation” on Google Search. However someone in Casey Anthony’s home searched for that query the same day her 2-year-old daughter was last seen alive. The new information adds to the criticism against the acquittal of Casey Anthony, who was originally accused for murdering her daughter. However, for the moment, authorities don’t know who made the “fool-proof suffocation” Google search.

The Orlando television station WKMG was the first to report that detectives overlooked the “fool-proof suffocation” Google search made June 16, 2008. On the overall, there were more than 1,200 Firefox entries that investigators in the Casey Anthony case simply overlooked. They did however check out the history of the Internet Explorer browser.

The Google search was made using Firefox, the browser Casey Anthony would commonly use for her internet browsing purposes. The browsing history also featured MySpace activity, which Casey Anthony used and not her father. The Associated Press notes that the Google search was initially misspelled. The user searched for the term “fool-proof suffication” and read an article about suicidal by poisoning and suffocation with a bag.

Casey Anthony’s attorney, Jose Baez discussed the Google search in his book explaining it was George Anthony who made it, not Casey. Apparently, her father wanted to kill himself after the 2-year-old drowned and helped his daughter cover it up. There was also a search on how to make chloroform, but Casey Anthony’s mother said she conducted that search by mistake, while looking for chlorophyll.

Before the Google search query was brought up, prosecutors said that the 2-year-old was first poisoned with chloroform and then died by suffocation after her nose and mouth were duct taped. When the 2-year-old’s body was found, six months after her disappearance, investigators couldn’t figure out what killed her for sure. The Google search might prove they were right, if they figure out who was the person in the Anthony house that looked for “fool-proof suffocation”.
