During Teddy and Evelyn's wedding reception, Teddy was found dead in Charlie's room. CSI arrived at the crime scene. Season 5, episode 17 (Fish In A Drawer). I do not own the rights of the content in this video.
It's been in the description since the day the video was uploaded, but given the number of comments asking what episode it's from, that appears to be difficult to find ;-)
They should have used the real actors from CSI, Eva LaRue and Adam Rodriguez for the investigator roles. We all know Charlie would have tried to hook up with Eva Larue.
y0y0 yeah I know it kinda crept up on me. Took a nap 30 minutes after watching it and I had nightmares at 1 in the afternoon. I woke up with my heart pounding.
