The dusty past of the first criminal investigation department

When Feng Chen and Bo Hao returned to the bureau, An Mu and Qin Yang also came back just in time. Bai Yumo was reading the information from W City. When Feng Chen and Bo Hao came back, he first handed Liu Qi's autopsy report to Feng Chen. dust.

Bai Yumo said: "The cause of Liu Qi's death was a torn heart muscle fiber, a heart hemorrhage, and a sudden cardiac arrest. In other words, Liu Qi was frightened to death. Judging from the unburned parts of Liu Qi's body, his face And there were no scratches on his body, so when the explosion occurred, Liu Qi was already what we saw."

"Scared to death?" Bo Hao felt a little unbelievable. According to their inference, Liu Qi should have been tied to a chair at that time. With Yu Mo's statement, Liu Qi should have been in the period between the murderer's departure and the detonation of the bomb. Within a short time, he broke free from the shackles and was about to leave, but was frightened to death before reaching the door.When I called Sanke, Sanke said that according to the recovery of the bomb fragments at the scene, the bomb was remote-controlled, and the time from when the murderer left to when the murderer detonated the bomb should be very short. With a bomb strapped to his side, Liu Qi can still be like this. Breaking free in a short period of time shows that his psychological quality is still very high, so what can scare Liu Qi to death?

Bai Yumo thought that Bo Hao didn't understand why people would be scared to death, so he explained, "When a person is in a state of extreme panic, the adrenal glands will suddenly release a large amount of catecholamines, causing the heartbeat to suddenly increase, blood pressure to increase, and myocardial metabolism to consume oxygen. The blood volume increased sharply. Excessive blood circulation hits the heart like a flood, tearing the myocardial fibers, bleeding the heart, causing cardiac arrest and death." After speaking, Bai Yumo shook the information in his hand, "I read Now, according to the autopsy report from over there, all four of the deceased were killed by the blast. The skin was exploded and the burnt area was relatively large, so it is impossible to determine whether they were shocked by electric shock before their death."

Feng Chen asked Bai Luo, "Xiao Bai, where are you?"

Bai Luo said: "According to the data, the modus operandi of this case is very similar to that of the serial bombing case. , that is, in the last case, no one’s fingerprints were left in the deceased’s house except the deceased, and in this case Liu Qi’s house also had no fingerprints of anyone else. In the fourth case, when the murderer entered the deceased’s house through the window, he left I forgot to erase the fingerprints. The murderer was Wang Fan, a vagrant. The police found Wang Fan based on his fingerprints, and also found the remote control at Wang Fan’s home. No entry or exit."

Qin Yang snapped his fingers, "In other words, Wang Fan is indeed the murderer, there is no problem, so could this case be a copycat crime?"

Feng Chen rubbed his chin, it's still early to make a conclusion, Feng Chen looked at Bai Luo, "Where's Guan Ke?"

Bai Luo pursed his lips and shook his head, "The information on the shell has also been sent, but the test results from the third department have not yet been released, so there is no way to compare them."

Feng Chen took a look at Bo Hao, and Bo Hao understood that he would take out the diary found from Liu Qi's house and give it to Bai Luo, asking Bai Luo to check the location in the diary.

Bai Luo took over the diary and moved the information on the table aside. When Bo Hao saw the photo on the table, his eyes widened instantly. Bo Hao showed the photo to Feng Chen, who looked at Bo Hao puzzled. What's wrong?

Bo Hao opened his mouth, that Ah Piao from yesterday.
