Karen Kolchak

Karen Kolchak is an unseen resident of Woodsboro, California. She worked at the video store with Randy Meeks.

Background
During the remainder of his senior year at Woodsboro High, sometime in late-1996 or early-mid 1997, Randy continued to work at the video store. While she was judged and outcast (due to her appearance) by many who visited the video store, namely Dewey (who referred to her as "Creepy Karen").

Randy, however, would have conversations with her while working and found her sweet and easy to speak to. One day, while putting videos away at the porno section, one thing led to another, and he lost his virginity to her.

Hollywood
His younger sister, Martha Meeks, who is now 17 (in 2000), and a senior at Woodsboro High visits the studio and runs into Sidney, Dewey, and Gale.

She urges them to see a video. The video is none other than her older deceased brother, Randy. He mentions his murder and briefly says,"...giving up his virginity to Karen Kolchak probably wasn't a good idea". So, he placed the blame on their relationship for his death in the second killing spree.

Randy, knowing someone was going to judge her when he says who he lost his virginity, quickly defends Karen and says in the video, "Shut up! She's a sweet person. We were putting away videos and... things happen" Prompting him and Gale to laugh. It was played for laughs, because Randy was likely to be killed either way due to being one of Nancy Loomis' prime targets.
