Cindy Anthony: Caylee Could Climb into Pool Without Help

Attorneys defending Casey Anthony Friday showed what they hope will be a compelling fact when jurors deliberate: photos of 2-year-old Caylee climbing a ladder into the family's swimming pool.

The photos also showed the toddler's grandmother, Cindy Anthony, supporting her from behind, USAToday reported Friday. However, Cindy Anthony later testified that she [Casey] could climb into the pool by herself, adding that they swam together daily, People.com reported Friday. The defense hopes the photos strengthen their case that Caylee drowned and was not murdered.

The prosecution claims Casey Anthony suffocated her daughter, Caylee, with duct tape in June 2008, then stored the body in the trunk of a car. Casey Anthony didn't report the toddler was missing for 31 days.

Casey Anthony has been charged with first-degree murder. If convicted, she faces a possible death sentence. She has pleaded not guilty.

Prosecutors, who rested their case last week, have presented ample evidence that Casey Anthony lied repeatedly, and that she is a habitual partier, but whether they have proved beyond a reasonable doubt that she murdered her 2-year-old daughter Caylee remains an open question, The Washington Post reported.

Conversely, the defense has largely concentrated on the prosecution's forensic evidence, including an FBI technician's testimony that duct tape found attached to Caylee Anthony's decomposed skull was contaminated during testing by another technican.
