Zhang Cheng was puzzled at the time, but not long after talking to his wife, (at around 4 pm), a Chinese man and woman in their 40s knocked on the door. As soon as Zhang Cheng opened the door – he was sprayed in the face with a chemical substance and instantly lost consciousness. Zhang Cheng was unconscious for nearly eight hours. When he woke up – he found that Ambar Aiaz’s car and a supply of seafood were in the parking lot of their apartment – whilst her mobile phone and wallet were also in the house – but she and her daughter were nowhere to be found! 

At the same time, Zhang Cheng found someone had left a Chinese language note at home, which conveyed a warning: “We are monitoring you, do not call the police, and you will see your wife and children in a few days.” As a result, Zhang Cheng foolishly did not call the police. It was not until 10 days later, on December 2nd, 2019, that he went to the Police for help. The Police immediately launched an investigation. The first person they suspected was Zhang Cheng. In addition to the fact that he had not called the police in time – Ambar Aiaz’s mother stated that her daughter and Zhang Cheng had many quarrels – and that her daughter – Melissa – didn’t like him either. 

However, in the process of investigating the case, Zhang Cheng cooperated very well throughout the entire process – and also accepted and passed a polygraph test. When the police investigated the apartment where the three lived, they found a small amount of blood and a bloody handprint – but strangely, this handprint was smaller than the palms of all three of the family. After identification, the bloodstain matched Ambar Aiaz’s DNA. After that, the Police launched an investigation which dug up a series of surprising clues.
