Holly was the first victim of Norman Bates.
One Fourth of July, Holly checked into the Bates Motel. During her stay, she made sexual advances toward Norman, who was interested, tried to have her wait at the motel while he went to unclog a guest's toilet. Holly, however, ran up to the Bates home, stripping and getting into Norman's bed.
Soon, Norman donned the identity and clothing of his mother and stabbed Holly to death.
