A bunch of criminal police gathered in Yang Jun's hut in the slum, and the forensic doctor Feibai said to the captain Gao Yuan: "The deceased Yang Jun, male, 52 years old, unemployed, died between 1 and 4 pm yesterday, and the specific time needs to be further autopsied." However, we found a pinhole in the injection on the deceased, which is suspected to be related to the death of the deceased. As for the rest, you should ask the forensic department. ”

"Okay, Feibai, I'm going to trouble you. ”

"Captain, we forensic section...... Didn't find it. There were only fingerprints of the deceased Yang Jun at the scene, and the footprints were also Yang Jun's, including the surrounding surveillance, only Yang Jun was photographed entering the slum alone. "The forensic department was quite helpless to say that it had not found and proved the cleverness of the murderer, and it also proved the incompetence of their forensic department," however, we found a note on the table with the letter D written on it in a bright red pen, however, the color of this pen was a little strange, and after a blood test, it was found that it was written in blood. ”

"Team Gao, good news, after our visit, we found that Lin Ruoyun, the young lady of the Lin family, had bought Valium in the pharmacy. Criminal policeman Xiao A rushed in excitedly and shouted excitedly.

"Without further ado, the Lin family will be interrogated immediately. Gao Yuan immediately said loudly.

"However, Gao Team, will the Lin family really kill people?" said an older criminal policeman in a low voice, "With the consistent style of the Lin family, there shouldn't be any killings." ”

"Anyway, let's be arraigned first. Gao Yuan was also a little helpless, he finished college with the support of the Lin family, and then came to the criminal police team, he believed in the Lin family more than anyone else, but ......
