At about seven o'clock in the morning, Forensic Doctor Qin personally sent the autopsy results over, "I wrote out the autopsy report overnight, which should be of some help to you to solve the case." ”

"Thank you."

Forensic Doctor Qin smiled slightly, "The duty is the same as Officer Bai guessed, the blood stains on that refill are Wang Cuihua's, and the murder weapon is the refill." Strangely enough, though, I didn't find the killer's fingerprints on the refill. It is preliminarily inferred that the murderer should have been wearing gloves or something like that. ”

"The murder weapon is a refill? Oh, my God! How much effort does it take to insert a refill into a person's artery? ”

"I recognize the brand of this kind of refill, and it is sold in the stationery store in front of every middle school, and after the refill I used before was broken, I bought it at the stationery store near my house."

When Bai Jingyu heard this, his eyes couldn't help but tighten, and he became more and more sure of one of his conjectures.

"If this kind of refill is bought in a stationery store, will it mean that the murderer is a student?"

When Zhang Zheng heard this, he couldn't help but deny, "Which student can have so much strength?" Besides, how can any student run to a nursing home to kill someone? Unconscionable! ”

Bai Jingyu's eyes swept over the picture of the refill on the autopsy report, and after a few seconds of silence, he said, "Maybe the murderer disguised himself as a student and went to the stationery store to buy a refill, and then went to the nursing home to commit the murder, so that it basically won't attract the attention of others." ”

"But why did the murderer make such a detour and kill people with a pen refill? It should be easier to hold a knife or something. ”

"The murderer's thinking is originally different from that of normal people, so it can't be deduced by normal people's logic. Maybe the murderer just likes excitement and likes difficult ways to kill. ”

Seeing that Bai Jingyu's tone was so determined, it seemed that he already had a suspicious candidate, "Officer Bai, do you already have the profile of the murderer in your heart?" ”

"That's right, I think this murderer should look a lot like a high school student, with a rebellious and arrogant personality, unusual, contemptuous of the police, killing people in such a cruel way, maybe just provoking us."

When Forensic Doctor Qin heard this, he couldn't help but feel a touch of surprise in his eyes, "Officer Bai, do you already have a suspicion?" ”

Bai Jingyu shook his head, "Not yet, but my intuition tells me that the killer may be like this." ”

Yes, such a strange modus operandi, such a strange modus operandi, he thought of the suspect who could have committed the crime last night - L.

As far as he knows, L has been secretly investigating the car accident and bombing case five years ago, and this early this morning, he and Zhang Zheng learned from the staff of the nursing home that someone had gone to the nursing home to find Wang Cuihua in the past two days and asked her about the bombing case that year.

Then, he learned that when Wang Cuihua hadn't entered the nursing home five years ago, he usually took the vegetables he grew to the flyover to sell.

On the night of the explosion, she happened to set up a stall selling vegetables at the head of the overpass, not close to or far from the explosion site, and was on the verge of the blast's reach.

I heard that at that time, she seemed to be stunned by the aftermath of the explosion and was sent to the hospital for first aid.

At that time, he also found out that the old man was a survivor of the explosion during the investigation, but Wang Cuihua was already in her seventies.

As an old man in his old age, he should have been frightened even if he was present at the time.

Therefore, he only regarded Wang Cuihua as a survivor of the explosion, but he did not expect that she was a witness to the explosion. "Wolf president, super pet!" The latest chapters of "Paw Book House" are free to read for the first time.
