Chapter 108 Who is lying? 9. Bloodstains
Han Jianye and Ye Bai stared at the surveillance video intently. Just as Ye Bai said, Jiang Wenhan in the video behaved very abnormally.
"Captain Han, I think he may have a psychological problem. Could it be anxiety disorder?" Ye Bai guessed.
Han Jianye shook his head seriously. "I'm not sure either. Judging from the surveillance footage, he behaved quite well, but we can't draw a conclusion based on the surveillance footage alone. His behavior is indeed very abnormal."
Then, the two continued to watch the second half of the video. Ye Bai and Si Yue did not continue watching here, so they left.
"What is he doing with the tissue?" Han Jianye asked puzzledly.
"Looks like he's wiping his hands?" Ye Bai replied.
"He must be picking out dirt from under his fingernails," Han Jianye analyzed.
Afterwards, Jiang Wenhan was caught on camera throwing the tissue into the trash can in the hall.
Suddenly, Han Jianye and Ye Bai's eyes met, with surprise in their eyes, and they ran towards the hall tacitly.
Luckily, the trash can in the hall had not been emptied yet, so the two put on gloves and began to search carefully.
The others who didn't understand were confused and didn't know what they were looking for.
Han Jianye explained: "Everyone, help look for it. Is there a bloody tissue?"
Because he and Ye Bai suspected that if Jiang Wenhan really killed Xu Aiyun, then there might be blood between his fingernails, and the action of picking his fingernails with a tissue just now might be to wipe away the blood.
Han Jianye found a crumpled tissue and turned it over. With his sharp eyes, he saw a red crescent-shaped stripe on the tissue.
“Found it.”
Han Jianye held the tissue paper in his hand. The only way to prove whether Jiang Wenhan was the murderer of Xu Aiyu was to see whether the bloodstain was from Xu Aiyu.
Who is lying and who is telling the truth will be revealed without being told.
Han Jianye handed the tissue to Mai Shaozhen, and they just needed to wait for the results.
At this time, Su Wan called Han Jianye.
"Captain Han, we have already asked the classmate who built blocks with Jiang Wenhan. He said that Jiang Wenhan came to his house at 7:54 and went home at 9:25. He said that he did not look very well when he came."
"Okay, I understand. Come back."
Han Jianye had just hung up the phone when Liao Wei's phone rang.
"Captain Han, I found that Jiang Wenhan has a very strange behavior." Liao Wei's voice was a little hurried.
Han Jianye frowned slightly and said in a serious tone: "Please explain it clearly."
"We followed him all the way and found that he was not in a hurry to go to school. Instead, he grabbed a cat basking in the sun on the side of the road and threw it to the ground. Seeing the cat screaming in pain, he actually laughed. It was a chilling laugh. He was completely different from the one he was last night. He had no love at all."
Liao Wei finished speaking, and then added: "I feel like he's a little perverted."
After hearing this, Han Jianye's eyes became deep, and he specifically instructed Liao Wei: "You continue to follow him, remember, don't lose him."
After hanging up the phone, Han Jianye fell into a brief contemplation, thinking over and over again about Liao Wei's words in his mind: "Completely different? If he is not pretending, then his behavior is abnormal based on the surveillance video..."
He looked at Ye Bai and said, "I wonder if Jiang Wenhan has a split personality?"
Ye Bai analyzed: "The split identity of dual personality shows that an individual has two or more completely different identities, each with its own name, age, gender, language habits, memory and behavior patterns.
In addition, switching between two identities can easily lead to memory loss, and the memories between different identities will not be continuous. Simply put, one identity may have no memory of the experiences of another identity.
Then there are the changes in his behavior. An individual's behavior and emotions may change differently as his different identities emerge. This also explains why Jiang Wenhan's behavior in the surveillance video was abnormal. I think your speculation that he has split personality is not unreasonable. ”
Si Yue and Qi Xiaolei came back at noon. They found out from a street store that Jiang Yucheng was riding an electric bike past his house at 6:55.
Surveillance video captured him riding an electric bike.
Han Jianye said, "At this point in time, Xu Aiyun was still alive. Jiang Yucheng did not lie. The incident happened not long after he left."
What he is more concerned about now is the identification report of the tissue, which should be out soon.
By chance, Mai Shaozhen called Han Jianye and said, "The identification results are out. The blood on the tissue came from Xu Aiyun. So, how did you find it? It's great, Han Jianye."
Han Jianye just grunted in response to this appraisal result, and he did not feel much joy in his heart.
After all, Jiang Wenhan is only 16 years old. Does he really have a split personality? When he stabbed the victim to death that night, was his main personality clear-headed? What on earth made him do such a cruel thing as murdering his mother?
Han Jianye has too many questions to ask him?
So he called Liao Wei and asked him to bring Jiang Wenhan back for questioning.
