Garrett Slan was a waiter at The Condor's Nest, the California University eating hangout. For weeks, items were stolen from students until one girl was raped. While Lenny Zeminski was arrested and released, he soon came clean and confessed that he had spent time with Garrett in a military prison and Garrett had been picking his brain about the co-eds. Garrett was initially stalking Clare Arnold to be his next victim, but a chance meeting at the Peach Pit After Dark with Donna Martin changed his focus to her.
Garrett ended up attempting to rape Donna, pinning her to the bed insde the Beach House. Before he could start, David Silver arrived home and hit him with a bat before Donna helped David knock him unconscious. Garrett was arrested and taken into custody.
Two years later, Garrett was released at a time coinciding with someone stalking Donna. David and Donna believed him to be responsible for several threatening phone calls towards Donna and sought a restraining order on him. Garrett denied the accusations, but Donna and David weren't convinced.
David and Tom Miller drove to Slan's house, where David had a confrontation and warned him to stay away from Donna. The police had been staking the place out and stopped them before it escalated into a physcial altercation. However, the next day, Garrett confronted Donna and David at the Peach Pit After Dark, antagonizing them and saying he should have finished the rape. he then punched David, who knew that they would get the restraining order as a result of that punch.
Ultimately, however, Garrett wasn't the one responsible when Evan Potter was revealed as Donna's stalker.
