Authorities say she rebuffed him by saying, "Get the hell out of my room, no!" After which he responded, "I thought that's what you wanted. I thought you loved me the way I love you."

Due to the statute of limitations, Montag is only eligible to be charged with crimes that occurred after July 1st, 1996, when the victim would have been 16 years old.

According to TMZ, Montag allegedly abused the girl 50 times during the five year period. His daughters Heidi, 28, and Holly, 31, are both too young to fit the profile of the victim. The sisters also have a younger brother, Sky Montag, who is 21.
