In the afternoon of the same day, Gu Song and Qiao Sheng returned to Jinshui County and handed over the DNA samples to Forensic Dr. Chen, asking her to make a comparison as soon as possible. Later, Qiao Sheng went to report to Director Xie, and Gu Song took the initiative to ask to join the monitoring team of Summer Time.

In the scorching summer, the scorching sun is on the head, and the work of squatting and waiting for the suspect is definitely a chore.

Gu Song greeted his colleagues who had changed shifts and got into the summer car. A wave of heat mixed with the choking smell of smoke hit his face, almost making him lose his breath.

He unbuttoned the two buttons, grabbed an old newspaper thrown in the car by someone as a fan, looked at Xia Shi with admiration and said, "You are really good, the car is as hot as a sauna, you can sit still." ”

"If you can't sit still, you have to sit, and you can't keep the air conditioner on when the car is parked." Xia Shi wiped the sweat on his head, and while staring at the clinic diagonally across the road, he asked Gu Song in wonder, "Why are you here to make a fuss when you are too hot?" How comfortable it is to stay in the office. ”

"I miss you, can't I?" Gu Song smiled and touched Xia Shi's cigarette case and lighter, and as soon as he took out half of the cigarette butt from it, Xia Shi stretched it back, and said angrily: "Your brain is hot and confused, right?" If you have something to say, let it go quickly, don't disgust me if it's okay. ”

"How do you know I'm wrong?"

"Nonsense." Xia Shi glanced at him, "If you have nothing to do with me, will you take the initiative to come here to accompany me to suffer?" ”

"Hey, you still know me." Gu Song stopped joking, and returned to a serious expression on his face. "In the summer, you take the time to help me inquire about Xinlei's situation, I can't contact her."

"What's wrong?" As soon as he heard that it was about Xinlei, Xia Shi immediately cheered up and asked worriedly, "Didn't you see Xinlei when you went to the hospital today?" ”

Gu Song shook his head helplessly and truthfully relayed Nurse Cui's words. "Don't you think Xinlei's discharge from the hospital this time was too sudden? Obviously, the problem at home has not been solved......"

"How do you know it's not resolved?" Xia Shi asked rhetorically, "Maybe in the past few days, they have tried to get Xin Lei to accept the news of Professor Chu's death. ”

"Even if that's the case...... Gu Song frowned, paused for a few seconds and said, "Nurse Cui's attitude makes me a little strange. I suspect she's hiding something from me. What if Xinlei's actual condition is not as good as she says it is? ”

"What do you want me to do?"

"Find Xinlei's family first and see if you can get in touch with Xinlei. Her family has no enmity with you, and she shouldn't turn you away. If that doesn't work, we'll think of something else. Anyway, I have to make sure Xinlei is safe, otherwise I will always feel unsure. ”

"Okay, that's on me." Xia Shi took out a cigarette from the cigarette case, lit it and stuffed it into Gu Song's mouth, smiled meaningfully and said, "Don't get me wrong, I'm not doing this for you." ”

Surveillance efforts for several days on end did not make any progress. Luo Tong went back and forth between his home and the clinic every day, working and living step by step, without any suspicious behavior or contact with any suspicious people.

In just a few days, Luo Tong's body has lost a lot of weight, and his originally angular cheeks have now sunken deeply, making him look like a terminally ill patient.

The DNA comparison results confirmed that the hair that fell at the scene of the crime did indeed belong to the suspect Jiang Ran. In order to find Jiang Ran's whereabouts as soon as possible, the county public security bureau has issued a notice of assistance to all grassroots police stations, asking them to assist in handling the case, and to conduct a carpet investigation of all hotels, rental houses, and other places in Jinshui County and surrounding towns and towns, so as to find out Jiang Ran's temporary foothold in Jinshui County.

According to the analysis of the current situation, Jiang Ran obviously came to Jinshui County for Luo Tong.

Director Cheng of the City D Psychiatric Rehabilitation Hospital confirmed that Jiang Ran's illness had indeed been cured, so she was allowed to go home. She is not the kind of psychopath who is aggressive and does not harm society. Unless you are stimulated very severely, you can generally control your emotions.

Jiang Ran's cousin also said that everything was normal after Jiang Ran was discharged from the hospital. They lived together for a few days and found that Jiang Ran's attitude towards life was much more positive than before, and he was full of expectations for his future life.

It can be inferred from this that Jiang Ran's original purpose in coming to Jinshui County was to find Luo Tong to reunite and pursue his happiness again. Unfortunately, she found that someone by Luo Tong's side had taken her place.

Perhaps there was some unknown agreement and secret between them, and Jiang Ran thought that he had been betrayed. Anger and jealousy filled her heart, causing her to lose her mind and eventually arouse her desire to kill.

Feng Yuhua's death may just be a warning and temptation, her real target is actually Luo Tong's lover, Tang Jing. It stands to reason that Jiang Ran should get in touch with Luo Tong soon after getting rid of Tang Jing. But since the incident, the police have never seen Jiang Ran's shadow again.

Tang Jing died on the night of July 13, and police surveillance of Luo Tong began on the morning of July 17. Perhaps during this period, Luo Tong and Jiang Ran had secret contact, and something unexpected happened.

Gu Song suspected that Jiang Ran might have encountered an accident, and suggested that Qiao Sheng directly bring Luo Tong back to the criminal police team for questioning. Qiao Sheng did not approve of this approach. They had already dealt with Luo Tong twice and knew that man's strength. In the absence of any evidence, it is not easy to ask for valuable information from Luo Tong's mouth. Fortunately, with the assistance of the grassroots units, they quickly found the house where Jiang Ran was temporarily rented.

On the evening of July 19, Qiao Sheng personally led a team to a rental house in the north of the city to arrest people. They walked around the front and back of the house, and after confirming that the suspect could not escape from all around, Gu Song knocked on the door vigorously.

After waiting for a moment, no one in the room responded. Qiao Sheng gave Gu Song a look, Gu Song took a few steps back, flew up and kicked open the rotten and tattered wooden door.

It is a very old house with poor interior facilities. After entering the door is a living room of less than ten square meters, with a wooden table and two chairs against the wall (one of which has fallen to the floor). On the left-hand side is the kitchen and bathroom, and directly opposite is an equally small bedroom. The door was open, revealing the messy beds and luggage scattered on the floor.

Gu Song only stood at the door and glanced at it hurriedly, then turned to the others and said, "Don't come in yet, it's not ...... here."

"Ah, senior brother." Before Gu Song finished speaking, Qi Ruonan's voice exploded in the silent alley. "Look, there is blood on the door frame, Jiang Ran really has an accident."
