Guns N' Roses Bassist -- Creeper Is Stalking My Wife ... Or Daughter ... I Can't Tell

The hot wife of Guns N' Roses bassist Duff McKagan is scared for her life and the life of her two teenage daughters, claiming a man has been stalking them all the way from Arizona -- but the weird thing ... it's not clear who the man is really after.

Susan Holmes-McKagan (above with Duff) has just obtained a temporary restraining order against 21-year-old Story Walker Bannister, claiming the Phoenix man showed up at her L.A. home last week while she was traveling with Duff.

According to the docs, Susan's mother was home at the time watching the girls -- one sixteen, the other 13 -- and Bannister demanded to see her "daughter."

Since it was Susan's mother who was speaking to him, it wasn't clear if Bannister was referring to Susan or one of Susan's teenage daughters -- but Susan's account is still really creepy as hell.

According to Susan's mother, Bannister refused to leave the property until he saw who he came to see ... and that it was "destiny" that brought him to the home. According to the docs, Susan's mom called police who hauled Bannister off for a psychological evaluation.
