Closer and Closer
Kate Saunders (Kim Delaney) realizes that all of the doors of the locations the killer has been have been handicapped accessible ones, which then helps lead to the realization that her friend, B.J. Conners (John J. York) is the killer. However, she doesn't realize this until after she has let him into her house. He then realizes that she knows, and tries to kill her. However, she gets away from him and hides upstairs. He comes after her, but she prevails and pushes him out the second story, where he plummets to his death.
