The time of the 7-year-old's death has become a crucial issue in the capital murder trial of her neighbor, David Westerfield. She was missing for 26 days before rescuers found her naked, badly decomposed body along a roadside. Prosecutors claim she was killed within the first couple days of her abduction — when Westerfield says he was alone on a camping trip. But Westerfield's lawyers say the state of her remains indicates the defendant was already under police surveillance when she was killed and, therefore, he could not be the perpetrator. The defense called a pair of forensic entomologists who said bug evidence supported that theory. Prosecutors fought back with their own time-of-death experts. Here's a summary of the contradictory expert testimony.
