Miriam is the daughter of Eugene Wegner, the owner of Emerald Ranch. It is known that Miriam was in a relationship with a local farm boy by the name of Joshua Burgess. However, after Joshua died after an "accidental shooting," Miriam has been forced to stay inside the family's house and is therefore rarely seen outside. Miriam can be seen looking out of the upstairs window around midnight and noon.
