(CNN) - Someone conducted keyword searches on "chloroform" using a desktop computer located in the home Casey Anthony shared with her parents, a computer examiner testified Wednesday in Anthony's capital murder trial.
The searches were found in a portion of the computer's hard drive that indicated they had been deleted, Detective Sandra Osborne of the Orange County Sheriff's Office testified.
However, she told jurors, deleted material remains on a computer's hard drive and can be retrieved until it is overwritten by new data. It had not been overwritten on the Anthonys' computer, she said, and "a complete Internet history" was obtained.
Anthony, 25, faces seven counts in the death of her 2-year-old daughter, Caylee, including first-degree murder, aggravated child abuse and misleading investigators. If convicted, she could face the death penalty.
The toddler's family last saw her on June 16, 2008, but no one alerted police until July 15, when the girl's maternal grandmother tracked down the suspect and demanded answers.
Prosecutors allege Anthony used chloroform on her daughter and suffocated her by putting duct tape over the little girl's mouth and nose. They allege Anthony put her daughter's body in her car trunk before disposing of it. Caylee's skeletal remains were found in December 2008, less than a mile from the home of Anthony's parents.
Anthony has pleaded not guilty and denied having anything to do with her daughter's death. Defense attorney Jose Baez has said that when all the facts are known, it will become clear his client is innocent.
