"Secondly, why did the murderer choose a nurse from the same hospital, is there any special connection between that hospital and the victim?"

"Officer Su is right, we think so too." Chen Hui nodded excitedly, "So, we want to apply to the head to investigate the First Mental Hospital." ”

Xu Sa touched his eyebrows, pondered for a moment, and slowly spoke, "Just because a few victims are nurses in a psychiatric hospital, it is a little difficult to fully investigate the First Psychiatric Hospital, at most we can only ask the First Psychiatric Hospital to cooperate with the investigation." ”

"Unless you can come up with more powerful evidence, in this case, I can still go to Sun Ju to talk about it."

"In short, let's let He Xingchen continue to compare." Xu Sa clapped the board, and secretly sighed in his heart, fortunately he had the foresight to ask He Xingchen to come over, otherwise this case would be enough for them to go around in circles.

He Xingchen didn't know that he was pinned on such a big hope, and he was tapping on the keyboard with his fingers, trying his best to investigate the staff information of the First Mental Hospital.

Su Tong looked around the office of the serious crime team and didn't see Su Qing, and leaned towards Zhou Li in the seat next to her, "What about Su Qing, why didn't you see her?" ”

Zhou Li is helping He Xingchen keep an eye on the surveillance video, trying to find out the suspicious characters hidden in the flow of people.

She stared at the screen and disappeared almost three times, barely blinking her eyes during the period, sour and astringent. Hearing Su Tong's question, he didn't dare to move, just stared at the screen and replied quickly, "I don't know, I haven't seen her since Officer Su went to the hospital." Most likely, she herself knew that she had gone too far this time, so she didn't have the face to meet people. ”

She had a good impression of Su Qing before, after all, she was an Interpol, but later after seeing Su Qing's targeting of Su Tong, her favorability towards Su Qing gradually decreased to zero.

After all, compared to Su Tong and Su Qing, the relationship between them and Su Tong is closer.

"Alas, Xu Sa, it's just that they don't believe me, why don't you misunderstand Su Qing." Su Tong sighed helplessly, "I fainted because of my own reasons, and it has nothing to do with Su Qing at all......"

"That's it!" He Xingchen slammed up from his chair, and looked at everyone with a pair of black and white eyes through thick glasses, "I compared the identity information of the seven victims, and these seven people are really nurses in the First Mental Hospital."

On their information, the hospital wrote all resignations, and the time of resignation was different, the earliest was three years ago, and the most recent one was a month ago! ”

As soon as they heard this number, everyone fell silent.

It was another month ago, and now they're almost numb to that time.

It's as if all the cases they are in contact with now start from a month.

But if that's the case, then what or who planted the seed a month ago.

Thinking of this, a chill rose in everyone's backs.

If these cases were really planned by someone a long time ago, then how deep was the man's conspiracy, and what was their purpose?

"He Xingchen, immediately print out a copy of the information, and I'll go to the Sun Bureau to investigate and allow." Xu Sa immediately made a decision and ordered, "Su Tong, you can briefly relay the autopsy situation on Zheng Lao's side to everyone." ”

Everyone quickly divided the labor, He Xingchen's discovery was undoubtedly a breakthrough in the previous case, if they were smart enough to seize this opportunity, maybe they would be able to catch the murderer.

"The seven deceased were all from the First Mental Hospital, could it really be such a coincidence?" Wen Yan on the side muttered in a low voice.

The strange feeling that had been haunting him before reappeared, what was wrong?

Sun Ju learned that Xu Sa had made a discovery, and he was also very cooperative with the work, so without saying a word, he approved Xu Sa's investigation application with a stroke of a pen.

Everyone immediately wasted no time and set off directly towards the First Psychiatric Hospital.

The First Psychiatric Hospital was built in the nineties of the last century, and it can be said to be the oldest psychiatric hospital in City B, and it has been renovated several times during this period.

The current dean is Wei Sen, who Wen Yan talked about before, a well-known scholar in the dual fields of neurology and psychology.

The hospital's address is in the western part of City B, not far from the abandoned building where they had previously dealt with a series of jumps.

Because of the special nature of the mental hospital, Rao is Xu Sa can't break through with the investigation application, but must contact the dean first and symbolically obtain the dean's consent before entering.

What they didn't expect was that there was another chaos waiting for them in the hospital.

The two black SUVs of the serious crime team parked outside the gate of the No. 1 Psychiatric Hospital, Xu Sa took the investigation application and his own documents to the doorman, and was about to explain their purpose when suddenly a loud gunshot rang out.

"That was ......," the crowd looked at the white buildings in the gate.

The doorman was also frightened and had no idea what was going on.

"That's gunshots, everyone stay safe." Xu Sa quickly pulled out his pistol, took the time to look back at Su Tong, who was still in the car, thought for a while and said, "Wen Yan, you and I go in, and the others are waiting for my orders outside!" ”

Wen Yan is naturally meaningless, as long as Su Tong doesn't have to go in, it doesn't matter if he gets in or not.

"Xu Sa, the situation inside is unknown, it's too dangerous for the two of you to go in!" Su Tong hurriedly stuck his head out of the car window.

"Boss, Officer Su is right." Chen Hui and Li Hua also nodded, "Let's go in with you, one more person and one more strength." ”

"I'm not going in to fight in a group now, what do you want so many people to do!" Xu Sa glared at Li Hua and Cheng Hui, "Do you know who is staying here?" The gun only rang out, and the number of guns should not be large, and it is possible that the patient was holding a gun. Wen Yan is with me, and if I meet a patient, he can help me. ”

Everyone was silent, and indeed according to Xu Sa's words, this was the best arrangement.

Su Tong wanted to say that she went in with Xu Sa, but the scene of the last time in the orphanage suddenly appeared in her mind, making her swallow her words back.

She has already been involved with Xu Sa once, and she can't be involved with Xu Sa for the second time.

Xu Sa made arrangements, and sneaked in with a gun with Wen Yan.

Li Hua and Chen Hui waited outside, calling for help and waiting for Xu Sa's order at any time.

Su Tong looked at the backs of the two, not only a little nervous in his heart.

The area of the First Psychiatric Hospital is not large, and you can enter the entrance of the hospital about 100 meters from the main entrance.
