The prescription bottle the character "Tom Cooley" had in his possession when the CSIs were searching his room contained Flunitrazepam, a drug that has not been approved for use in the U.S. but is legal in other countries.
The actor who plays Sheriff Anderson in this episode, Gonzalo Menendez, also appeared on CSI: Miami (2002) portraying Clavo Cruz, a recurring antagonist during seasons 2-5.
