She attended the Prom, where the massacre happened and she was one of the 11 survivors.
She is described as a tall, very thin girl with long frizzy brunette hair, somewhat similar to Sue Snell's hairstyle. She is one of the girls who threw tampons at Carrie White in the locker room and ended up in detention by Miss Collins. After Carrie had gotten her period and was sent to Mr. Morton's office she is seen walking with another girl to her class. For a brief second, she is seen walking down some stairs and then back up with her boyfriend while Freddy DeLois is talking to Ernest Peterson. At the Prom, Ruth is with Helen Shyres and during Carrie's rampage, she tried to escape along with Helen. But both fell to the ground in the attempt.
Ruth is last seen running to Helen's dead body but it appears to be too late.
- This is the only adaptation where Ruth dies.
- Ruth, along with Rhonda Wilson, Mary Lila Grace and Alice Litten are the 6th Mortimer Snerds members to be killed by Carrie White.
