Prosecutors, Defense Battle Over Forensic Evidence in Casey Anthony Trial

Defense attorneys and prosecutors continued to battle over forensic evidence in Casey Anthony's murder trial, in which the Florida resident has been accused of killing her daughter, Caylee Anthony, age 2. If convicted, Casey Anthony faces a possible death sentence. She has pleaded not guilty.

Casey Anthony, 25, is accused of suffocating her daughter with duct tape on June 16, 2008, then storing the body in the trunk of a car. Caylee Anthony's remains were found in woods near the Anthony home in metro Orlando, Fla. on December 11, 2008, following an extensive search. Casey Anthony claims that Caylee drowned in a pool.

Duct tape was found attached to Caylee Anthony's skull. However, Dutch Forensic Expert Richard Eikelenboom, currently based in Colorado, told the jury Tuesday that he found no trace DNA on the tape, CBSNews.com reported. Meanwhile, Prosecutor Jeff Ashton has attempted to discredit Eikelenboom's science.

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 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.
