WARNING! POSSIBLE SPOILER BELOW! I'm interested in renting the Spanish release of Twin Peaks Season 2 and don't know who killed Laura Palmer. However, I'm afraid I found out who the killer was by accident. Please don't read the following spoiler tag if you have not seen Season 2, but if you do know who Laura's killer was please take a look: Comedy Central aired an old rerun of Saturday Night Live hosted by Kyle MacLachlan. There was a Twin Peaks skit that said Leo had been discovered as being the killer. Is it true that Leo was the killer in the actual Twin Peaks show? Thanks!
