Trends With Benefits: When a picture of a recently-murdered college student is uploaded anonymously to Twitter, the CSIs are brought in to track down the killer using a combination of forensic techniques and social media. The victim, Pete Moyer, was an aspiring TMZ-style journalist who had made a lot of enemies on his campus for spilling secrets and gossip on his blog. The team eventually learns that Pete accidentally fell to his death during a struggle with a suicidal classmate. Pete was recording their conversation in hopes of using it as proof that an esteemed university professor had raped her, along with multiple other girls.
