Corrected entry: In the flashback scene, where we see the abusive husband shooting his wife in the head against a wall in their home, Sarah and Grissom do not discover any plastering or other repair to the wall (although they do discover the victim's blood). However, during the victim's autopsy scene, we learn that the shot to the victim's head was through-and-through. (This is an important plot point, since it means that the bullet's distinctive composition is not immediately discovered.) Wouldn't the bullet have gone into the wall? Is there any realistic way the murderer could have repaired the damage without Sarah or Grissom discovering it?
Corrected entry: After the store clerks enter their pottery store and find the store robbed and a dead body, it shows the Las Vegas Police and the CSI team drive into the front of the building in patrol cars and Suburbans. On one Suburban, you can see the police lights on the right passenger side strapped on to the visor, on the other side you can see the rear-view mirror is directly above the steering mirror. Last time I checked, rear-view mirrors are NEVER above the steering wheel.
Corrected entry: Forensics notices 3 small dots on a piece of paper on the ransom letter, and states its from the drum of the printer - and if the ransom note was from the printer of the family of the kidnapped child, the paper would have that same mark. Sara grabs a piece of paper out of the in tray on the printer, and says that mark doesn't appear. Of course - the mark is left when the printer prints and the paper gets fed through the printer. She took a piece of paper from the in tray - paper that has yet to go through the printer.
