The neighborhood used is so clearly the neighborhood from Desperate Housewives not even the house numbers are changed, nor is the scenery, for where a murder took place. You half expect to see Bree Van De Kamp come out of her house to greet the CSI's even though CSI take is supposed to take place in Las Vegas.
The CSIs tell John Nolan that Lexi tried to send the video clip of their abductor to someone. The suspect realized she was recording him during the video, so there is no way she could have opened her text messenger, typed in her father's phone number, and attached the clip to send it.
