At the time, Edward Werner’s long list of suspects included a rickshaw driver who was reportedly covered in blood at the time of the murder and one of Pamela’s grammar school teachers who had made sexual advances towards her (via That’s Mag).

According to ABC, Paul French, the author of the 2013 book “Midnight in Peking,” believed there were numerous possible suspects for the crime. As That’s Mag reported, Edward Werner discovered shocking files referencing an undercover sex cult, heroin addicts and disappearing brothels,” which French also uncovered decades later as he researched the murder.

After reading “Midnight in Peking,” author Graeme Sheppard wanted to investigate further. Sheppard added Werner’s father to the list of suspects, citing his controlling behavior and violent outbursts. Per ABC, Sheppard notes that Werner’s father disliked when his daughter brought home boyfriends, and once broke the nose of Pamela’s boyfriend, Han Shou-ch’ing. However, Sheppard doesn’t believe that her father was the murderer.
