angel to reconstruct what might have happened on anna's final day. >> we're at the place where anna marie and charlie resided for a few months, and then anna finally moved out because she couldn't take the abuse anymore. >> he could have came home after say killing her and come her and changed his clothes and washed his hands and did something. because there was information that he did change the sink in here after the disappearance. >> police got a warrant to search the apartment seven months later. the results were disappointing for the family. >> to quote one of the inspectors, the place was completely sanitized. there was not a drop of evidence anywhere, not a hair, no samples at all, nothing. >> very much like five years before when charlie's sister-in-law elizabeth bump had disappeared. he and bump were rumored to have had an affair. when police searched her car, no physical evidence was found either.
