Chapter 240: It Must Be Fresh Blood

"Okay."

Black Box nodded, and then continued to ask, "You say...... Can expired blood still detect DNA? ”

"Basically undetectable, in human blood, red blood cells and platelets have no nucleus, only white blood cells have a nucleus, and the survival period of white blood cells is only 7~14 days, after the survival period, white blood cells will be ablated, and then the blood in the blood bag has no genetic material."

Fei San explained with a serious face.

Hearing this, the black boy's eyes widened, and a trace of horror instantly appeared in his eyes,

It seems that Officer Hao's statement that someone threw the blood in the blood bag and caused the blood rain is mostly untrue, because Qiao Fei donated blood half a year ago, and her blood has long been out of genetic material, so yesterday's blood rain was not Qiao Fei's blood donated half a year ago, but Qiao Fei's recent fresh blood!

Thinking of this, Black Box immediately said goodbye to Fat San and walked out of the hospital.

Standing at the entrance of the hospital, taking out his mobile phone, Hei Zai dialed Officer Hao's phone.

"Hey, Blackboy, how's your doing?"

Officer Hao's voice came from the phone.

Black Box replied, "I asked, there was no theft in the hospital at all." And, Brother Hao, I don't think the kind of possibility you mentioned is basically impossible. ”

Officer Hao was obviously stunned for a moment, and after figuring out the meaning of Heizai's tongue twister, he asked curiously, "What do you mean by that?" Did you make any discoveries? ”

"I found an old classmate who was a doctor and asked, he said that after the blood leaves the human body, 7 to 14 days, the white blood cells in it will die cleanly, and only the white blood cells in the blood have a nucleus, carrying genetic information, the white blood cells are dead, and the DNA in the blood is not detectable, that is to say, the blood in that blood rain cannot be the blood bag half a year ago, it will only be fresh blood!"

Hearing this, a trace of horror also appeared in Officer Hao's eyes, if it was really as Heizai said, then Qiao Fei was likely to have encountered an accident at this time......

In Meng Xiang's house before, when Qian Wancang told him about the "blood bag guess", he secretly breathed a sigh of relief for Qiao Fei, if the blood rain came from the blood bag half a year ago, then Qiao Fei would have a great chance of surviving, and now, the "blood bag guess" was rejected, and it also proved that the blood in the blood rain was fresh blood, then, Qiao Fei would be more than lucky!

"How's it going over there? Have you ever found someone running onto the rooftop and throwing blood? ”

Black Box asked suddenly.

Officer Hao came back to his senses: "I didn't find it, I checked all the surveillance of that day just now, and I didn't find any suspicious people." ”

"That's going to be hard!"

Black Box sighed helplessly, thinking that he had found some useful clues, but after some busy work, he found that this clue didn't work at all.

"Let's do it first, let's go back to the police station."

Officer Hao hung up the phone after speaking, then left the Deco Hotel and drove towards the police station.

…………

5:12 p.m.

In the office of the Linhai City Police Department, Officer Hao's mobile phone screen suddenly lit up, and then "ding dong" sounded.

Officer Hao shifted his gaze from the computer screen to the phone screen and found that he had received a text message.

clicked on it casually, only to see a paragraph displayed on the screen: "Officer Hao, come to the identification department, there is a major discovery!" ”

"Old forensic doctor!"

Officer Hao muttered, then got up from his chair and quickly ran to the office door.

"Why are you going?"

Black Box wondered.

Officer Hao ignored the black boy, and after leaving the office, he ran straight towards the identification department.

Soon, Officer Hao came to the identification department and found the old forensic doctor.

"What's the big discovery?"

Officer Hao asked breathlessly.

The old forensic doctor smiled and said nothing, and casually handed an appraisal report to Officer Hao.

Officer Hao took the appraisal report and quickly flipped through it, the more he looked back, his eyes widened, and the expression on his face became extremely excited.

"That's great! That's nice! Thank you so much! ”

Officer Hao grabbed the old forensic doctor's hand and shook it vigorously.

"No thanks, that's what I'm supposed to do."

The old forensic doctor said politely.

Officer Hao nodded heavily, gave the old forensic doctor an admiring look, then turned around and left the forensic department and ran towards the office.

At this moment, Black Box was standing at the door of the office looking in the direction of the Identification Division, and he saw Officer Hao suddenly running to the Identification Department excitedly, there must be some major discovery, as Officer Hao's partner, he was very curious about this major discovery.

"Black Boy."

After Officer Hao saw the black boy, he raised the appraisal report in his hand and shouted excitedly.

"Brother Hao, what are you taking?"

Black Box asked curiously.

After Officer Hao approached Heizai, he threw the appraisal report on Heizai: "I found a few hairs at Meng Xiang's house this morning, and took them to the identification department to identify the DNA, guess what, four of these hairs are from Qiao Fei, and guess who is the one?" ”

"From Meng Xiang?"

Black Box guessed.

"From the owner of that unknown blood! The DNA of that hair is the same as that of unknown blood! ”

Officer Hao said in surprise.

"Could it be that the owner of the unknown blood is Meng Xiang?"

Black Boy's eyes widened, his eyes were full of excitement and a hint of doubt.

"Uh...... Although those hairs were found in Meng Xiang's house, it was not certain that the hair was Meng Xiang's, so it was not certain that the owner of the unknown blood was Meng Xiang. ”

Officer Hao's tone calmed down a bit.

After hearing this, the black boy's eyes, which were as wide as bull's eyes, slowly returned to normal: "Why don't we arrest Meng Xiang and test his DNA?" ”

"I'm afraid this won't work, Meng Xiang hasn't committed a crime now, at least there is no evidence to prove that Meng Xiang has committed a crime, we have no right to force a person who hasn't committed a crime."

Officer Hao said leisurely.

Heizai's eyes sank: "Brother Hao, you also said just now that those hairs were found in Meng Xiang's house, and there are Qiao Fei's hairs in them, what does this mean?" It shows that Qiao Fei has been to Meng Xiang's house, and among the few hairs you found, four of them belong to Qiao Fei, why are there so many Qiao Fei's hairs?

There seems to be only one possibility, that is, Meng Xiang once grabbed Qiao Fei's hair and abused her, which caused Qiao Fei to lose so much hair, and if I go one step deeper, I now seriously suspect that Qiao Fei's disappearance is related to Meng Xiang nine times out of ten! ”

Officer Hao was obviously stunned for a moment, and felt that what Hei Zai said was very reasonable,

And he remembered that those hairs were found on the carpet of Meng Xiang's bedroom, and they must have fallen not long ago, otherwise they would have been cleaned up long ago.

In other words, Qiao Fei had been to Meng Xiang's bedroom before he disappeared,

And Meng Xiang said that he and Qiao Fei had broken up for a long time, and at this time, it seemed that Meng Xiang was lying!

That's interesting.

Why did Meng Xiang lie?

Could it be that Coffie's disappearance really has something to do with him? He lied to absolve himself of responsibility!
