CSI: NY, Season 8

Mac (to Jo):
Who do you see in this picture?

Jo:
You, me, Sheldon, Danny, Lindsay.

Mac:
How many lab techs?

Jo:
Three. They were assigned to the scene.

Mac:
The only people taking crime scene photos were Danny and Hawkes. We're all in the picture, including the techs... so who took that picture?

Jo:
You're thinking the killer, and this photo was a message.

Mac:
Someone who could get access to our cell phones and send us that photo, someone who wouldn't look out of place at the crime scene, who could gain entry to the evidence, someone who's playing "catch me if you can." Not only was our victim part of the crime lab, I'm thinking so was our killer.
