The White Hat Killer was an infamous serial murderer in Cascadia. The White Hat Killer would capture and psychologically torture victims before eventually killing them. The killer would then pose in a white hat, face and body obscured, for a selfie with the deceased victim. Authorities had assumed the killer was a man and were shocked when it was ultimately revealed that the killer was a woman.

Found to have severe psychological illness and to have suffered tremendous abuse as a child, the killer was eventually committed to Wimahl Psychiatric Institute where she remains to this day.

The last 24 hours of one of the victims, Henrietta Jean, were brought to life through a concept album by Mr Darling.
