The reason why this case of Zhuo Changdong was temporarily concluded as an accidental fall was completely because a scratch was found in the rented house where Zhuo Changdong was found.
The scratch was close to the balcony and there was a necklace on the ground not far from it.
After careful observation and comparison by the forensic officers, they found that the scratch on the ground was caused by the necklace.
Since the rented house Zhuo Changdong and Guo Xinru lived in was located in a remote area and it was an old building that was about to be demolished, there weren't many neighbors nearby and there weren't any surveillance cameras either.
Besides, the incident happened after 10 at night, so nobody saw Zhuo Changdong when he fell down the building. When someone found out that Zhuo Changdong died after falling down the building, it was already the next morning.
