Situ Ce couldn't figure it out, so he compared two old fingerprints. One of them was indeed from Yan's family. It's easy to understand. Since this knife belongs to their family, it's reasonable to have her fingerprint on it.

Situ Ce decided to ask Yan.

After he put the things down, he pushed the door out. Yan still stood in the corner of the house, lowering his eyes and silently. Situ Ce walked over and said, "Yan, I ask you, have you touched a knife after the incident?"

Before Yan's answer, Helanbing said first: "She has never touched her, because before she came back, we had discovered the knife and put it away. She had never even seen the knife."

Situ Ce was stunned, as if he was unwilling to believe this. He glanced at Yan, who was quite haggard, and asked with some difficulty: "Is that true?"

Yan nodded slowly but still didn't say anything.

"Then why, there is your blood fingerprint on the knife?" Situ Ce said it very hard, as if he had used a lot of courage to say this.

As soon as this said, everyone in the venue was shocked. He Lanbing was sitting on the chair at the table, but after hearing the cry, he stood up: "You said the blood fingerprint on the knife is hers? How did you know?"

"How do you know you don't need to ask, just believe me." Situ Ce did not turn his eyes away, and kept looking at Yan, with a sad expression.

However, Yan did not even have a tremor reaction, and only said plainly: "That morning, I killed the old hen and stewed soup for my husband. I wouldn't kill him, so I got a lot of blood in my hands."

Situ Ce knew that this excuse was far-fetched, but he would rather believe it was true and said anxiously: "The blood you stuck to the knife is chicken blood?"

Yan nodded.

"Okay! I will know immediately whether it is chicken blood." After that, he turned around and entered the wing room.

He took out a cotton swab from the survey box and extracted blood samples from various places such as the tip of the knife, the blade and the hilt of the knife, and then used anti-human hemoglobin detection reagent strips to test it. He found that all the test materials were positive, that is, the blood on the knife, including the blood on the blood fingerprint, were all human blood!

Yan is lying!

Situ Ce also used blood samples from various blood marks on the knife, including blood samples on the blood fingerprint, and then used abo blood type detection card for testing. It was found that the blood types of all the test materials were type O! In other words, it is likely that they were all the blood of the deceased! Including the blood fingerprint blood!

This conclusion was expected by Situ Ce, but it was not among his hopes. He hoped that the peasant woman who had two children alone was true. He believed that no matter what the peasant woman did, she must have her reasons. Now, the facts are facts, and he could not avoid them. He could only face it, although it was so cruel.

Situ Ce packed up his things, came out again, smiled bitterly, and said, "You didn't tell the truth just now! The blood on the knife is human blood, and it is your husband's blood! I ask you, since you have never touched this knife after your husband died, why did you leave your blood mark on the hilt? And why is the blood stain from your husband?"

Finally, Yan's delicate body trembled slightly, and her lips became paler. However, she still didn't say anything and looked sad and helpless.

He Lanbing was really surprised and happy when he heard this, and asked Situ Ce urgently: "What you said just now is true?"

"Yes! In addition to the strangeness of blood on the hilt of the knife, there is another even more strange thing in this case, that is, the weapon and knife itself!" Situ Ce could only reveal the truth in his heart.

"The weapon itself? What does it mean?"

Situ Ce said: "Since the murderer hated the deceased so much that he stabbed the dead thirty-two times, the hatred between the two has reached the extreme. The murderer killed it quickly, and then broke into the house to commit crimes when the deceased was sick and bedridden, so there should be premeditated. Since this is the case, the murderer should prepare the knife himself in advance, and should not go to the deceased's house to commit crimes with the knife. This is not in common sense."

Helanbing nodded frequently.

Situ Ce did not look at Yan. He was worried that his sad and helpless expression would blow away his courage to tell the truth, so he could only say in one breath: "I looked at the corpse of the coroner in this case in detail. The depth of each wound was inserted into the coroner with a small ruler to measure the depth. Although there were many wounds, most of them were not too deep, and no bone was stabbed. This means that the murderer's strength was relatively small!"

Helanbing nodded slowly: "I have noticed this too."

Situ Ce continued: "There is another very strange feature of this case, that is, the contradiction in the details on the scene and the reinforcement of the behavior!"

"Contradictory and reinforcement?" Helan Bing's eyebrows slightly frowned, "What does it mean?"

Situ Ce felt smoke in his throat. He swallowed hard, and continued a little awkwardly: "Contradictory means inconsistency between the previous and subsequent behaviors. The murderer was very cruel and stabbed the dead thirty-two times. However, after-handling the murder weapon seemed very naive. He actually hid the knife under the pot lid of the dining table at home and did not wash away the blood on it. This is contradiction. Most of the murderers with this characteristic are women. Because women are rich in emotions, sensitive and timid, fear, hesitation and helplessness after the crime will be much stronger than men. Therefore, it is reflected in the behavioral style, which reflects the cruelty when the crime is committed and the hesitation in the after-hand handling of the scene. This is also contradiction. As for reinforcement, the murderer is always worried that the deceased will be resurrected, so although he has killed the deceased, he will continue to carry out harm behaviors to prevent the deceased from resurrecting from the dead. This is also a characteristic of women's psychology."

"So that's how it is." He Lanbing also looked at the sad Yan family. He said, "After you said this, I found something strange. If it was an outsider who committed an offense, it should be taking the knife away and throwing it away on the road, right? How could he hide the knife under the lid of the deceased's dining table?"

"That's right, comprehensive judgment, the murderer should be a woman, especially the blood fingerprint on the knife, which has clearly told us that the murderer is, she!" Situ Ce did not look at Yan, but everyone knew who he was talking about.

Yan didn't move. Finally, she slowly raised her head, looked at Situ Ce, and let out a long breath, as if this breath had been accumulated in her chest for many years. She slowly said, "It was me, it was me who killed him! He deserved to die! He deserved to die long ago!"

Helanbing said: "What the hell is going on? After that!"

Yan gently pushed away the two children beside him, stroked the scattered hair on his temples, and began to untidy his clothes.

Situ Ce and Shi Meng and other male constables quickly turned around, and Yin Yadan scolded: "Hey! What are you doing?——Ah?! The injuries on your body..., what's going on?"
