Amanda Hughes

She was an elderly wealthy American who was killed 17 years prior to the current timeline. As the cause of her death could not be determined, it is possible that she was poisoned by APTX 4869 or a similar substance. Haibara has yet to confirm whether she saw Amanda's name on the list or not. Amanda apparently had contacts to two American intelligence agencies, the FBI and CIA. She died while staying at a hotel which was also occupied by shogi champion Kohji Haneda whom Amanda was a big fan of, and who was killed the same night. It was proved that she visited his hotel room. Conan suspects that a Black Organization agent posed as a bodyguard named "Asaka" and killed her with a drug.

The bodyguard then vanished completely afterwards.
