Yes, ma'am. Next, the prosecutor had Karen identify Holly's purse, her keys, her wallet. Karen sounded like she was holding back tears. And eventually, she turned to the judge and said... Everyone in the courtroom stood up to see what was going on. The judge stood up, too, to maintain order. Karen had fallen to the floor. She was sobbing and had trouble catching her breath.

The judge said Karen suffered a panic attack that required medical attention. The defense was worried that Karen's distress would make it impossible for the jury to listen to her testimony objectively and asked for a new jury to be called. The judge did not agree. Once Karen had recovered, he asked the jury to come back in and ordered the trial to continue.

A forensic pathologist testified that Holly was shot in the back of the head, likely at close range and likely by a .32 caliber bullet. The defense challenged this by asking the pathologist about some unknown variables in his analysis, like how far away the person who shot Holly was from her and whether the bullet fractured before hitting her.

In response, the pathologist said it was true that because of those factors, he could not know for certain the size of the bullet that killed Holly. Zach's ex-girlfriend also took the stand. She had previously verified Zach's alibi, telling authorities that she was at his house the morning of Holly's kidnapping and he was sleeping. But she testified that she wasn't sure what he did that morning.
