Detective Norris questioned the Milliken estate housekeeper Beatriz, and then Alan's wife Julia. Since the reports of both women were different, Norris determined that Julia was lying. Julia eventually confessed that Sherry Palmer had been there earlier in the night, and that Sherry convinced Julia to let Alan suffer through his heart attack. This led Norris to an investigation into Sherry. Norris contacted Sherry, who told him that Julia's allegations were false and that she was with the President at the time of Milliken's death. Norris got into contact with President Palmer, whom Sherry had persuaded to vouch for her alibi.
