The police increased manpower to search the surrounding area of the crime scene and brought in six police dogs from the county, but they still couldn't find the child's heart.
Subsequently, the case was handed over to the Criminal Police Brigade of Guangyuan County. However, after three months of investigation without any progress, they had to ask for help from the city level.
The case was then taken over by their police team, led by Lu Jianfei. Upon receiving the request for help, he immediately led the team to Guangyuan County to learn about the situation.
They visited Zhou Kaieri's family, as well as the surrounding neighbors and people from the same village.
At first, they also believed it was a revenge murder case, so they focused on villagers who had conflicts with the Zhou family.
After investigation, they successfully identified a few villagers who had disagreements with the Zhou family, but all were trivial matters and not serious enough to lead to murder.
