When they first show Karen's body, there's no Caving magazine on the floor. The Caving magazine isn't shown for several minutes. When they show her body under the Coroner's sheet, with a close-up of Karen's face, you can suddenly see the Caving magazine.
The days of the week on the newspapers shown during the initial search are wrong. The Tacoma Messenger gives the first date as Sunday, April 19, 2003, but that date was a Saturday. The next day, Issue 198 calls it Monday, April 20, 2003, which was of course a Sunday. The next date two days later is given as Wednesday, April 22, 2003, but this would have been a Tuesday. Finally, April 25th is given as a Saturday, this was a Friday. The dates are consistent among themselves, but are all one day off.
