Corrected entry: The CSI team determine a woman died after accidentally ingesting ricin (which she tried to use to kill someone else). She died within minutes of sticking her ricin covered pen into her mouth. According to the CDC, death by ingestion of ricin will occur within 36-72 hours (depending on potency, amount, etc.), not a matter of minutes. And, death could not have been from inhalation during her manufacturing of the ricin. They make it a point to show her burnt-looking tongue as the place where ricin was introduced to the body.
A Night at the Movies - S3-E19
Corrected entry: Greg Sanders while reviewing evidence, tells Stokes the song "He Ain't Heavy (He's My Brother)" is by Harold Melvin. It is actually a song by The Hollies.
Correction: Character mistake.
Corrected entry: When Greg is coming to see if Hodges has processed the water from the fountain, Hodges asks if Greg can't spell since he wrote "funtain water" on the glass. Greg answers that his folks are Norwegian and this is the way they spell it. That is incorrect. Fountain in Norwegian is "fontene."
Living Doll - S7-E24
Corrected entry: Brass and Grissom go to see Trevor Dell, one of the Dell foster children. Foster children do not take the last name of the Foster Family unless they are adopted, and they never adopted any of the 13 Foster Children.
Correction: It's entirely possible that they shared the same last name without being related. Dell isn't that unusual.
Corrected entry: DNA results usually take weeks instead of just days like usually happens on the show.
Correction: They have the lab in-house, so they don't have to send the samples off to another lab; and they prioritise the cases by importance, so samples from the 'big' cases go first. DNA tests themselves don't take weeks, sending them off to a lab, and waiting for the lab to get around to testing them, does. Them having the lab in-house relies on suspension of disbelief, but isn't inherently a mistake.
Corrected entry: In the scene where Sidle is watching the gorilla documentary, the cover of the pamphlet reads "The Gorilla In It's Natural Habitat." The correct possessive form would be "The Gorilla In ITS Natural Habitat."
Correction: So whoever typed it made a mistake. Character stupidity and bad spelling are not mistakes.
Correction: It is true that Ricin was introduced in the mouth, but it does not state when. Yes, Aaron saw the woman put the pen in her mouth, but this didn't necessarily have to be the only point when she did so. She showed she does have a habit of chewing on her pen so the poison could have been introduced to her body before she was in the cage.
