Wrong Interrogation Room, The First Cracked Case Shocked the World

By this time.

Tang Xin had to trust Ning Cheng's judgment.

This is really too coincidental.

Ning Cheng just got the clues, the prescription of sleeping pills, and the murder weapon kitchen knife, and Zheng Yunyun surrendered to the crime and confessed to the murder.

It is really suspicious!

"Mr. Ning Cheng, why are you so sure that you are Zheng Yunyun?" Tang Xin couldn't help feeling lucky.

"If Zheng Yunyun kills, what is her motive for killing?"

Ning Cheng shook his head and said, "According to the information from the investigation and interview, Zheng Yunyun has always been taken care of by her grandmother Zheng Ling as her sister, and she has never been abused."

"She sympathizes with her sister, but why did she kill grandma Zheng Ling?"

Tang Xin asked, "Then why did Zheng Yunyun do this?"

"Protect her sister!" Ning Cheng narrowed his eyes and said seriously:

"I have been investigating my sister Zheng Lingyun, but I have ignored my sister Zheng Yunyun's investigation!"

"If my guess is not wrong, after my sister Zheng Lingyun killed my grandmother Zheng Ling, she should have notified her sister Zheng Yunyun immediately;"

"Then my sister Zheng Yunyun rushed from the hospital to the house where the crime happened to solve the aftermath for my sister and create a scene of robbery and murder!"

"If Zheng Yunyun can really do this, he's really smart!" Tang Xin couldn't help sighing, "It's a pity!"

"What should we do now, there is no sister Zheng Lingyun's fingerprint on the murder weapon, only sister Zheng Yunyun's fingerprint, and now my sister Zheng Yunyun has surrendered and pleaded guilty to murder, how can we overturn it?"

Just at this time.

Ning Cheng's phone rang again, this time from Mu Xiaoyu.

"Ning Cheng, I have already arrived at the provincial hospital and checked the prescription!"

Mu Xiaoyu's voice came from the phone, and even Tang Xin could hear it clearly.

"The prescription was not issued by my sister Zheng Lingyun, but by my sister Zheng Yunyun. This result is different from what we judged yesterday!"

"I have already found the prescription form from the doctor who prescribes the medicine in the provincial hospital, and the photo is on the VX!"

Tang Xin couldn't help but flash a smile, and said to Ning Cheng who was holding the phone:

"It seems that you hit Zheng Yunyun's mind. She did deliberately open a prescription list, and put the prescription list in the trash can of the conspicuous community so that you can easily find it."

"The fingerprints on the murder weapon, plus the prescription for sleeping pills, make her suspect."

"I really have to admire Zheng Yunyun's wisdom. This layout is almost difficult to solve. She has to take the blame for her sister!"

"what should I do now?"

Tang Xin stared at Ning Cheng with wide eyes, as if she wanted to see a headache on his handsome face.

But it didn't.

Calm down!

"I already know what you said, that doesn't matter!"

Ning Cheng said to Mu Xiaoyu on the phone, "I asked the doctor who prescribed sleeping pills, when was the prescription issued?"

"I asked, the doctor said that the order was issued on the 15th the day before yesterday!"

"Ask again, he's lying!"

"it is good!"

Mu Xiaoyu hung up the phone briefly, followed Ning Cheng's order and went to ask the doctor.

"Why do you say the doctor who made the order is lying? Wasn't the prescription written on the 15th the day before yesterday?"

"impossible!"

Ning Cheng shook his head and said, "I said that my sister Zheng Yunyun is not a murderer, but my sister Zheng Lingyun!"

"Zheng Yunyun wants to put the suspicion on herself, and takes the blame on herself, so she has to make her murder appear reasonable, so the opening date of the prescription will be on the 15th of the day before yesterday, so that she seems to be a premeditated murder."

"But after my sister murdered yesterday, she should have been so flustered that Zheng Yunyun was surprised;

So if you want to fake your suspicions, you can only open a list. That prescription list was opened on the day of 16th yesterday. "

"And my sister Zheng Yunyun is a nurse in a provincial hospital by profession. A prescription drug like sleeping pills can easily make the police think of her. This is exactly what Zheng Yunyun wants to achieve!"

"That elder sister Zheng Yunyun is really smart!"

Tang Xin sighed, feeling pity for her sister Zheng Yunyun.

The elder sister Zheng Yunyun, of course, is extremely wise and able to set up such a situation in such a short period of time.

But in the end, he met the higher existence of Ning Cheng, and the plan was doomed to fail!

Not long after, Mu Xiaoyu called again:

"I asked again and warned the doctor, but the doctor still said that it was opened on the 15th the day before yesterday."

"Okay, I'll go there myself!"

Mu Xiaoyu couldn't find out the result, so Ning Cheng had to go to the hospital in person.

By the way, let's know what kind of person Zheng Yunyun is!

After driving for more than half an hour, Ning Cheng came to the hospital and saw Mu Xiaoyu at the door.

Then Mu Xiaoyu took Ning Cheng to see the doctor who prescribed the medicine.

The doctor's surname is Qin, and he is in his early 40s. He is already bald, and his slightly sparse hair is set with a bit of wax.

"Officer, what else can I do? I said that Zheng Yunyun gave me the order on the 15th the day before yesterday."

Dr. Qin's mouth was full of complaints, and he said angrily:

"I'm on duty now. I'm very busy every day. This is a matter of life and death. Can you bear this responsibility?"

"I know the importance of a doctor's work, Doctor Qin, I will take 3 minutes of your time!"

"If I can't get the information I want within 3 minutes, I'll leave immediately!"

Ning Cheng sat down in front of Dr. Qin unceremoniously and stared at him blankly.

now!

A mad and fierce temperament overflowed from Ning Cheng!

Although Ning Cheng has a handsome face!

But Dr. Qin stared at Ning Cheng's ruthless eyes, and he was instantly horrified, and a coolness penetrated his back!

Knock up!

The watch was removed by Ning Cheng and placed on the table.

"The 3-minute timer starts!".
