Ah, 2009. The days before iPhones were ubiquitous, when Twitter was just starting to catch on and Taylor Swift was still a country singer from Nashville, not one of the world's most famous pop stars. It was also the year that the now-superstar tested out her acting chops on an episode of CSI.
In honor of the two-hour series finale of the landmark procedural, which has run for 15 years, let Swifty lead you on a walk down memory lane to the episode "Turn, Turn, Turn," in which the then-19-year-old played murder victim Haley Jones.
The CSI team—specifically Nick, who volunteered to take the case on his birthday—had encountered the 16-year-old several times over the previous year while investigating deaths at her parents' motel, and in E! News' exclusive clip from the episode, you can see one of those interactions.
