After finding out, the deceased's name was Cui Mao, 51 years old this year. His wife, Zhang Xiuting, was only 27. The age difference between the two was 24 years, a full two zodiac cycles, enough to be her father.
Faced with various doubts, the only way to uncover the truth was to ascertain the cause of death, so Cao Gang called the forensic doctor to bring the deceased back to the station for a further autopsy to determine the cause of death.
Meanwhile, Cao Gang also contacted the technical team from the criminal investigation unit to rush to the scene for inspection.
He simulated the situation at the time based on the deceased wife's description.
The deceased fell from the fourth floor. Cao Gang simulated the reaction after slipping; a normal person's instinct after slipping would be to grab anything within reach.
The stairway wasn't wide; if the deceased had really slipped, he could have easily grabbed the railing to steady himself.
