Revealing mistake: While Horatio and Alexx are examining the prostitute's body, you can see the corpse breath in a side view.
Revealing mistake: The compound Heptan-2-one is mentioned several times in this episode. The actress concerned persists in pronouncing the last syllable 'one' as in the number 1, whereas its correct scientific pronounciation should be as in the word 'bone' ie. sounds like 'own'. Nitpicking certainly, but a dead giveaway to any viewer with a basic knowledge of chemistry.
