A somewhat unbalanced woman, Amanda was having an affair with Paul Dutton. When he broke off the affair for his wife's sake, Amanda was very upset and decided to kill them both.
Using a hex bag she killed Janet Dutton first, using a spell that made all of her teeth fall out and caused her to bleed to death in just a few minutes. Amanda began her spell on Paul Dutton as he was biting into a burger. The spell created maggots in the burger. Upon realizing this Paul began to choke. However, Dean and Sam arrive in time to find the hex bag and burn it before it kills him.
Amanda was panicked about the spell backfiring when Sam burned the bag, when her arms began to be slit open by three deep slashes cut vertically down her wrist to her inner elbow on each arm, replicating a suicide.
The demon Tammi had hexed her.
