The dozens of knives on their bodies were not in the lethal zone, but they seemed to be deliberately tortured, and the real cause of their death was drowning.

So this case is quite complicated, because they still don't know what kind of environment the murderer committed the killing.

In the autopsy room, Lu Chen followed behind Jun Yanjin, covering his nose while looking at the forensic doctor Duan Xu: "Has the identity of the newly discovered corpse been confirmed?" ”

Not to mention that the murderer was cruel, and even rose to the point of perversion, the victim found last night had a hot face full of smoke holes, and there was no way to perform facial recognition.

Duan continued: "The couple who came to report the case this morning said that they were their daughters, and they had collected blood samples from the two, and Xiao Liu was already conducting DNA comparisons. ”

“……”

The day after Jun Yanjin came back, he had already locked up the suspect.

The reason was that he found a small piece of scrap of paper in the mouth of the last deceased, and after investigation, it was revealed that it was a cigarette wrapper named 'Taishang Huang'.

So along this line, they collected the people who bought this kind of cigarette in Weizhou, plus the profile of the murderer's appearance, and soon, they locked up several suspects.

In the afternoon of the next day, an arrest operation was carried out.

Jun Yanjin was leaning on the side of the off-road vehicle and smoking, and two middle-aged couples were fighting at the entrance of the police station.

Liu Han followed Lu Chen out of the hall of the police station, and ran towards the door: "Okay, okay!" Don't fight, and don't look at what this place is! ”

Lu Chen also took out a cigarette: "Yan Jin, it's really thanks to you this time, otherwise the case wouldn't have been solved so quickly." ”

Jun Yanjin disagreed, and raised her chin at the door: "What's wrong?" ”

Lu Chen snorted: "The parents of the last deceased, the DNA comparison came out, it is their daughter, but ...... It's just that the woman's daughter doesn't match her father.

It's not ...... I just found out that his wife cuckolded him, and the two of them were arguing.

"When my daughter died, I realized that the child I raised was not my own species, and I really don't know whether it is a blessing or a curse."

Jun Yanjin twisted her eyebrows: "Didn't Duan Xu say at the beginning that it wasn't their daughter?" ”

Indeed, before the DNA comparison was carried out, Duan Xu was extremely sure that it was not their daughter.

Lu Chen smiled: "It seems that you don't know that type O blood and any blood type will not give birth to a child with type AB." ”

Jun Yanjin was stunned and a little distracted: "What did you say?" ”

Lu Chen: "This is what Duan Xu told me, type O blood and any blood type can't give birth to a child with type AB, the deceased is type AB, when her father came to register, he said that he was type O, so Duan Xu denied that it was not their daughter...... Huh? Yan Jin, why are you going? ”

Jun Yanjin got into the car in a panic, and lowered the window while reversing: "Achen, the arrest will be handed over to you, I have more important things!" ”

“……”

On the way back to Dugu Island, Jun Yanjin's hand holding the steering wheel was almost shaking, and the voices of the nurse and Lu Chen kept lingering in his ears:

"The patient has blood type AB and currently needs a blood transfusion, so I will first go to see if the blood bank has sufficient ............"

"O blood type and any blood type cannot give birth to a child with AB type ......"

“……”

Jun Yanjin's eyes were scarlet and he stepped on the accelerator.

Cheng Fuyu is AB blood type......

Qin Lan is a blood type O......

Blood type O and any blood type cannot give birth to a child with AB type!

So...... Then there is only one possibility!

Cheng Fuyu and Qin Lan are not related by blood!
