Casey Anthony, the 22-year-old Florida woman charged with the murder of her 3-year-old daughter Caylee earlier this year, has some terrifying evidence stacking against her. According to UPI, a recent search showed "that terms such as 'neck breaking' and 'household weapons' were entered into the computer at the Orlando home of Caylee's grandparents where Caylee and her mother, Casey Anthony, also lived." In addition, "Police said they believe Casey Anthony used a computer to read up on chloroform, a chemical that is used to put people to sleep but can also be deadly in high enough concentrations."
