"It's not dirty here, you see you're tidy and tidy, much cleaner than our office!"

Officer Hao said as he took out a small plastic bag from his pocket and handed it to the old forensic doctor.

"What is this?"

The old forensic doctor took the plastic bag and looked down, only to see that there were a few hairs in the plastic bag, two of which were quite long, like women's hair.

"Is it possible to detect DNA data through hair?"

Officer Hao asked casually.

"Absolutely."

The old forensic doctor affirmed.

The corners of Officer Hao's mouth raised: "That's good, help me test the DNA of these hairs, the sooner the better." ”

The old forensic doctor glanced at Officer Hao: "It will take five hours to complete the detection of such a few hairs at the earliest." Come back in the evening and get it. ”

"No problem!"

After speaking, Officer Hao walked out of the dissection room of the identification department in a hurry.

These hairs were found in Meng Xiang's bedroom, when Qian Wancang and Meng Xiang were in a relationship, Officer Hao wandered around Meng Xiang's villa when he was idle and bored, and when he walked to the bedroom, he found a few very long hairs on the ground, obviously, this is a woman's hair.

Curious, Officer Hao picked up two long hairs, and picked up a few shorter hairs, planning to take them back to the police station for testing.

If the long hair is Qiao Fei's, then, Meng Xiang is lying, they didn't break up at all, otherwise Qiao Fei's hair would not have appeared in his bedroom!

If it was another woman's, it would prove that Meng Xiang had indeed broken up with Qiao Fei, and there would be no need to waste time on Meng Xiang.

In addition, the reason why Officer Hao didn't tell Qian Wancang about his hair was that he completely forgot to say it.

He trusted Qian Wancang very much, had no precautions at all, and was willing to tell Qian Wancang some more sensitive things.

The reason why Qian Wancang didn't see the hair in Officer Hao's eyes was also because Officer Hao didn't think about hair in his heart at that time......

After leaving the Identification Department, Officer Hao found Hei Zai and planned to work with Hei Zai to verify Qian Wancang's speculation as soon as possible to see if someone really threw blood at random with a blood bag, causing these two blood rain incidents.

"Black Box,"

Officer Hao patted Black Boy on the shoulder.

Heizai suddenly turned his head: "Yo, Brother Hao, you look very happy, isn't there any happy event?" ”

"That's smart, you guessed it, there is indeed a happy event, and I plan to share it with you."

Officer Hao said with a smile.

"What's the happy thing? Say it! ”

Black Box looked at Officer Hao curiously.

Officer Hao thought for a moment: "There has been a major discovery in the Bloody Rain case. ”

Black Boy glared: "Really? ”

"Of course, but it needs to be verified."

Officer Hao frowned.

"How do you verify it?"

Black Box asked impatiently.

Officer Hao looked at the time and said slowly, "Time is pressing, the two of us need to act separately." ”

"No problem, how do you say what to do? Don't sell it! ”

Black Box urged.

Officer Hao smiled: "You go to Linhai People's Hospital to investigate and see if there have been any cases of blood bag theft in the past six months." ”

"Stolen blood bags?"

"That's right! The forensic doctor detected sodium citrate, which is an anticoagulant commonly used in blood bags in hospitals to prevent blood clotting, and Qiao Fei donated blood half a year ago, perhaps because her blood bag was stolen, which eventually caused the blood rain incident. ”

Officer Hao said slowly.

Black Boy put on a suddenly realized expression: "I think it's really possible, in short, it's better than what you said before...... What bird blood is thrown down to form a blood rain is much more reliable. ”

"Since you agree with this speculation, then you should act quickly, Linhai People's Hospital is not far from here, hurry up."

Officer Hao urged.

"What about you?"

Black Boy asked casually.

Officer Hao replied: "I went to the Deco Hotel to check the surveillance from a week ago to see if anyone went to the rooftop with a blood bag. ”

"Okay, if there is any news to communicate in time, we must gnaw this case down!"

Black Box said excitedly.

Officer Hao patted Heizai's shoulder: "Don't worry, it will be!" ”

…………

Over the next few hours, Officer Hao and Black Boy split up.

Officer Hao went to the Deco Hotel, came to the monitoring room, and found two security guards to assist in an extremely detailed investigation of the surveillance video from a week ago, but did not find that anyone went to the roof with a blood bag, and even except for some hotel waiters who went to the roof to dry the sheets, no one else went to the roof roof.

After the black boy came to the hospital, he first came to the security room of the hospital and inquired about the blood bag theft cases in the past six months, and found that there had been no blood bag theft cases in the hospital for more than half a year, and there were no other theft cases.

It's no wonder that the hospital is full of cameras, and there are so many people, who dares to go to the hospital to steal.

Besides, if you accidentally steal into the morgue of the hospital, not only will you not be able to steal anything, but you may also be scared out of your soul......

Since there were no thefts, it means that the blood bags were not lost.

However, will the hospital send the blood bags to other hospitals?

For example, other hospitals need a large amount of blood transfusion, so they borrowed a large number of blood bags from Linhai People's Hospital?

Thinking of this, Black Box quickly leaves the security department and finds an old high school classmate who works as a doctor in the hospital: Fat Three.

Fei San is the attending physician of the Department of Respiratory Medicine, who is sitting in his own clinic at this time, waiting for the patient to come to the door.

"Yo, old black, long time no see."

After Fei San saw the black boy, he hurriedly put down the pen in his hand and said hello.

Heizai walked straight into the diagnosis room and sat opposite Fat San: "Long time no see, old classmate, hehe, I see you have lost a lot of weight." ”

"Where did I lose weight, I have gained more than a dozen pounds in the past few years."

Fei San quipped.

"I've come today to ask you about something."

Kurozai propped his hand on the table and looked at Fat San with a serious face.

Fei San was curious: "What's the matter?" You don't have respiratory diseases, do you? ”

"Nonsense, how did I get that kind of disease, I want to ask you, did your hospital give the blood donated by those donors to other hospitals."

Black Box asked.

Fei San thought for a while: "This happens from time to time, and our hospital often borrows blood from other hospitals. ”

"Can you find out where a donor's blood went?"

Black Box continued.

"It's not easy to check, after the donor finishes donating blood, his blood will be sent for examination immediately, and if there is no problem, it will be stored in the blood bank along with all the blood that is okay."

Fei San said slowly.

Black Boy pursed his lips regretfully and didn't speak again.

Fei San looked at the black boy and asked curiously, "What trouble are you in?" Why are you asking me this? ”

"There's no trouble, I just want to check a blood bag from half a year ago."

Black Box said casually.

"Blood bags from half a year ago?" Fei San smiled and continued: "The general shelf life of blood bags is only about 28 days, and the blood bags half a year ago have long been used, and you can't find them." ”

Hei Zai's eyes sank: "The shelf life of blood bags is only 28 days? What about after the expiration date? What do you do with the blood in the blood bag? Is it thrown away like garbage? ”

"Of course not, when hospitals deal with expired blood bags, they will generally use incineration and other means to destroy them, and they will not be thrown on the street, and although the shelf life of blood bags is less than a month, there will be basically no expired blood bags, and blood is a very valuable resource! The hospital has a set of blood donation management methods, and the amount of blood in the blood bank will be kept in a reasonable range, which will neither cause blood waste nor blood shortage. Hizo explained.
