(Capcom's primary storyline)
"Marlene was so proud of her white and blue necklace/It made her feel tall and left her quite breathless."
— Marlene's stanza in the Old Notebook
Marlene was one of the five victims that were murdered by the Baker family.
Marlene arrived at the house where the Baker family used to reside some time in 2017 due to unknown reasons. The sound that played when pointing the Dummy's Left Hand at where she died suggests that she was hanged with her own necklace, as suggested by the Old Notebook.
