Chapter 116 Found the murder weapon

After Xu Dayuan asked, he stared at Luo Suqin.

The old lady clasped her hands together and just shook her head lightly.

"The two of us only have one mobile phone. Why do we have to see ourselves in the census?"

At this time, Da Zhao came in from the outside, held up a cotton swab, and looked at Zhou Ning.

Zhou Ning walked over, Da Zhao lowered his voice and said:

"In the gap of the rear bucket of the tricycle, blood was found by spraying Luminol. I think that if the rear bucket is removed, more blood can be extracted from the back."

Seeing the actions of the two, Xu Dayuan walked over to the side of the old lady if he didn't understand anything.

"Let me re-introduce, I am Xu Dayuan, the captain of the First Brigade of the Criminal Police Detachment of Qindao City. I am not a police officer. We found dismembered bones around the Han Dynasty tombs in Xiaolongshan, Xinghua City. After the skull was restored, the deceased was Zhang Min'an.

My people found blood in your house just now, and you still want to tell me that your wife has returned to his hometown?If you are going back to your hometown, tell me which train you took on which day, and I can check it. "

Luo Suqin was stunned, grabbed the hem of her clothes and shook her head constantly, her feet went limp, and she slumped on the chair.

Xu Dayuan rubbed his hair, and grabbed the tablet in Xiao Liu's hand. On it was Luo Suqin's household registration information. In the marital status column, the word unmarried was very conspicuous. Seeing Luo Suqin's performance, he was a little crazy.

"I think you have read the news two days ago. This case was used by foreign media to hype it up. It is also an issue of public security in China and a human rights issue. It is not only the Qindao City Public Security Bureau, but also the city and the city. The Shandong Provincial Party Committee is under enormous pressure.

Let's not kill each other's patience, let me ask again, what is the relationship between you and Zhang Min'an?Don't tell me that's your wife, Zhang Min'an's household registration information says widowed. "

Silence, Luo Suqin didn't speak for a long time.

Xu Dayuan wanted to get up, but Zhou Ning stretched out his hand to hold him down. There was no point in being impatient at the moment. From Luo Suqin's performance, we knew that even if she wasn't the murderer, she was also an insider.

Zhou Ning raised the evidence bag in his hand, the old lady Luo Suqin looked sideways slightly, the evidence bag is transparent, and the contents inside are clear at a glance.

"Luo Suqin, I'm a forensic doctor. I just found a razor and a toothbrush at your home. These two items and the blood on the car are compared with the DNA of the deceased. The results can be obtained within three to six hours.

If you talk about it at that time, the nature of what you say will be completely different from what you say now, so I advise you to think carefully before answering Officer Xu's question.

In addition, I know that Zhang Min'an has bone cancer, and he has been sick for a long time. It is estimated that he has been treated for rheumatism, and he has been seen in Qindao and even in the provincial capital, but there is no further treatment.

Because further treatment means amputation. Of course, during the diagnosis and treatment, it may be discovered that he has other cancers. The problem on this leg may just be bone metastasis. Am I right? "

The word amputation seems to have stimulated Luo Suqin. Her face was pale, and her forehead was already covered with sweat. Although she was still sitting there, her eyes seemed to be unable to focus. She clutched her chest and had difficulty breathing. She struggled to squeeze out a few words .

"I didn't expect, I didn't expect things to turn out like this. I didn't. Kill people. I really didn't. Kill people."

Then he tilted his body and fell backwards.

Zhou Ning stood behind Luo Suqin, caught the old lady, put her on the ground, put her left hand on the carotid artery, and shouted at Da Zhao at the door:
"Da Zhao went to the bedroom to look for medicine. He looked in the bedside table and the chest of drawers to see if there was any nitroglycerin. Xiao Liu called an ambulance."

The two people moved instantly, Zhou Ning loosened Luo Suqin's belt, and began to perform cardiopulmonary resuscitation, Xu Dayuan stood aside, stomping his feet anxiously.

Such a sudden situation caught people off guard. At least someone had to be rescued, otherwise the case would end here again.

Da Zhao searched very fast, grabbed nitroglycerin and came over, Zhou Ning stuffed the medicine into Luo Suqin's mouth, Da Zhao took over Zhou Ning's cardiopulmonary resuscitation. From far to near.

When the emergency personnel came in, Xiao Zeng and the others also rushed into the yard.

Xu Dayuan waved his hand, signaling everyone to make way for the medical staff. The emergency doctor checked it. Zhou Ning glanced at the time and introduced the time of the onset and the rescue process.

The emergency doctor immediately measured Luo Suqin's blood pressure, performed an electrocardiogram, and administered emergency medicine. Seeing that she was in a stable state, she nodded towards Zhou Ning.

"The condition is stable. We are going to the hospital now. Is this a suspect or a family member? Are you following?"

Seeing Xu Dayuan waving his hand, Xiao Zeng quickly ordered the two to follow.

After the emergency personnel evacuated, Xu Dayuan stood in front of the main house and looked at the entire courtyard.

"Okay, Xiao Zeng brought people to cooperate with you to search for traces. Even if you buy or sell houses in the village, you can't settle down. You can't build new ones or expand them, and you can't enjoy compensation for demolition. You only have the right to use them. Xiao Liu and I will visit the surrounding neighbors. Go to the village committee to find out the situation."

Speaking of Xu Dayuan leading the people away, Da Zhao sighed and wiped the sweat from his forehead.

"Life is miserable. If I had known that I would bring a few trace inspections from other groups, how long would it take to work on just one camera? Comrade Zhou Xiaozhou, where do we start?"

Although he was complaining, he looked at Zhou Ning with excitement.

In fact, Zhou Ning had already looked at the main house just now. This is the concrete floor with some mottled and small cracks. If there is blood on this floor, it will definitely remain. This is not the first scene.

Thinking of the chainsaw traces on the bones of the deceased, Zhou Ning looked towards the east wing.

"The west wing is full of grain, and there are some freshly squeezed peanut oil. Go to the east wing and have a look. The tricycle is parked here, which means that this is a tool room or a utility room. If you can find a chainsaw, then the The residues are the easiest to extract, so the chain of evidence is complete."

Zhao Xinli laughed so hard that he couldn't see his teeth, put on his equipment, and trotted to the door of the east chamber with the investigation box. The two policemen also came over, took the luminol reagent distributed by Da Zhao, and started spraying in the east chamber.

After spraying the reagents, the policeman at the door closed the door, and Zhou Ning turned on the purple light in his hand. In the dark room, on the ground and on a table next to it, there were blue fluorescent lights, dripping, splashing, wiping, and diluting. There are all kinds of traces.

Around an iron box on the shelf, there are fluorescent fingerprints, as well as faint fluorescent traces of wiping and flowing.

Zhou Ning and Da Zhao walked over, turned on the flashlight, and shone at the iron box. Following the light of the flashlight, they could find that the surface of the box had been cleaned, and Da Zhao lifted the box and put it on the table.

At this moment, the door of the room had been opened, and the lights in the room were turned on. Da Zhao exhaled with nervousness and excitement.

"It's time to open the blind box, let's see if we can find the murder weapon!"

I stretched out my hand and pulled it, but the lid didn't open. There was a loud bang, and the combination lock next to the iron box shook a few times.

Da Zhao's face pulled his hips instantly, and he pulled the mask down a little bit with his waist inserted.

"Luo Suqin actually uses a combination lock. I came out in a hurry. I don't have a giant plier with a clip lock. Do you have that kind of giant pliers in your car? If not, go to the nearby hardware store to buy one!"

Zhou Ning raised his hand to stop Da Zhao's movement. The combination lock is four digits. After thinking for a while, he started to turn the roller on it and tried 1116. It was Luo Suqin's birthday and he couldn't open it.

Tried 0817 again, this time when the pull ring on the lock was opened, Da Zhao gave a thumbs up.

"Zhou Xiaozhou, you have a really good brain. Could it be the date of birth of the two of them?"

Zhou Ning nodded.

"The password is Zhang Min'an's date of birth."

Da Zhao grabbed the edge of the box and pulled it hard. Inside the box lay a hand-held single-tooth chainsaw.

This time without spraying with luminol reagent, the naked eye can see blood stains in the buttons and gaps of the chainsaw, and there are residual white bone chips on the saw teeth.

"Found the murder weapon!"
