Officer Wang looked at Zhao Yu, who was munching on his burger, and promised him,"don't worry, master. I'll continue to investigate according to your plan. I'll find out all the people related to the prison!"

"Yes," Zhao Yu said."According to the evidence we have so far, before Nong zhifa went to prison, he should have no mental problems. So, the most important part of the memoir of the murder should be in the prison!

"Now that the staff has finished the screening, let's check the prisoners!"

"Yes!" Officer Wang nodded.

Officer Wang said,"yes, I did a rough calculation, and there were nearly 5000 criminals who might have been in contact with Nong zhifa!"
