S5, E12: The body of young man is found in a tank at a wastewater treatment plant. M.E. Warner (Tamara Tunie) is able to identify a tattoo that says TE and it's the symbol for the fraternity Tau Epsilon. Benson (Mariska Hargitay) and Stabler (Chris Meloni) discover the deceased is Tyler Henry, treasurer of the Panhellenic Council. Tyler was a big man on campus and his father Xander (Gary Cole) is a very successful attorney. Tyler is living quite well supposedly off his web design activities, but in actuality he was making money selling advertising for a porn website. Initially, the Detectives suspect co-ed Chloe Spiers (Serena Williams), who had previously sued Tyler after she stripped for a wet t-shirt contest Tyler sponsored and had her pictures splashed all over the Internet. But she has an alibi. She was playing basketball out of state.
