Hanging up the phone, Gu Song's brain was a little dazed, and the whole person froze in front of the dining table for half a minute.

Qiao Nianzhen was frightened by his appearance, and asked nervously, "Who called, what happened?" ”

"Mom." Gu Song slowly came back to his senses and said apologetically, "I have to go to the scene, so I can't eat with you." ”

"What? Out of the field? Qiao Nian really thought that he had misheard, so he hurriedly put down the dishes and chopsticks and grabbed Gu Song's arm and asked, "Haven't you already resigned?" Why do you have to go to the scene to solve the case? ”

"The case is urgent, and I don't have time to explain it to you now."

"Then ......" Qiao Nian looked at his son sincerely distressed and said, "You can eat a few bites of food before leaving, you can't go to work hungry for a few minutes." ”

"Okay then." Gu Song didn't want to waste his mother's kindness, smiled helplessly, sat back down at the table, and devoured a few mouthfuls of food, and then went out of the house with his mother's nagging and instructions.

Half an hour later, Gu Song parked the car in the Ganges community. got out of the car and locked the car door, and just happened to meet Huo Yan, who was temporarily pulled to the criminal police team as a consultant like him. The two of them looked at each other and smiled, their expressions revealing a little helplessness. Indeed, on this Mid-Autumn Festival night that should be spent with the family, who wants to be called to the scene of the crime in the middle of the reunion dinner.

"Teacher Xiaohuo, I didn't expect us to meet again so soon."

"yes, I never dreamed that there would be a murder tonight. I had planned to take my parents to the rooftop to admire the moon later. ”

"Admire the moon......" Gu Song subconsciously looked up at the night sky, a full moon was hanging high in the sky, exuding a faint silver brilliance. It seems like it's been a long time since I've looked up at the moon like this. ”

"Me too." Huo Yan raised her head slightly, with a faint smile on her face, but the corner of her eyes stayed on Gu Song's side face with clear lines, as if the people around her were more pleasing to her than looking at the moon.

After a while, Gu Song retracted his mind and said to Huo Yan: "Let's go, let's hurry up and go to see the scene, if we delay any longer, Team Leader Xia will curse." ”

Room 403 is the house rented by He Yao, which has been cordoned off by the police as the scene of the "9.16 case". Ma Zhichen is He Yao's boyfriend and was once investigated by the police as the No. 1 suspect in the murder of He Yao. After proving that he had nothing to do with the two murders, only four days later, he also died in He Yao's home, which is really an unbelievable thing.

"You two come in with me." Xia Shi impatiently waved at Gu Song and Huo Yan at the door, looking very bad. He didn't know what kind of blood mold he had poured on, and as soon as he took office, he encountered murders one after another. If he hired two advisers and couldn't survive the current difficulty, from now on, he was afraid that he would not have the face to continue working in the detachment.

Coming to the central scene of the murder - He Yao's bedroom, Xia Shi concisely introduced the facts of the case to Gu Song and Huo Yan.

At about eight o'clock this evening, the big man who lived upstairs came home after walking his dog in the community, and saw a big gap open in the door of room 403. Because Room 403 was the scene of the crime that was cordoned off by the police, he didn't want to meddle in things, and he didn't have the courage to enter the house where the murder had happened alone, but he didn't expect that his shepherd dog would sneak in through the crack in the door in a mischievous manner.

Master Dang was frightened at that time, and stood at the door and shouted for a long time, but the mischievous shepherd dog refused to come out of anything, as if he had found something terrible in the bedroom inside, and let out a shrill barking sound. Feeling that the situation was not good, Master Dang boldly walked into the bedroom, only to see the scene in front of them.

"The forensic doctor preliminarily judged that the time of Ma Zhichen's death was about 6 o'clock this evening, and the cause of death was an injection drug overdose." Xia Shi pointed to the body on the bed that was tied up with hemp rope and continued, "The victim has multiple electric injuries on his body, and it is suspected that he was abused by the murderer before his death. Judging from the destruction of the door lock, the murderer should have broken into He Yao's home by violent means, subdued the victim in this bedroom, and tied him with hemp rope. It is estimated that when the murderer broke in, Ma Zhichen was sleeping in the bedroom, so the murderer controlled his movements with little effort.

For some purpose, after the murderer tied up Ma Zhichen, he was injured by electric shocks many times, and finally injected an overdose of drugs into his body, causing his death.

"Based on the shoe prints left at the scene, we speculate that the murderer who broke into the room was an adult male, about 180 centimeters tall and weighing 80 kilograms to 85 kilograms, which can be said to be very strong. It stands to reason that it would be easy for him to kill Ma Zhichen, who was much thinner than him, but he didn't bother to kill him in this way, which shows that the means of crime are of vital significance to him.

"We have not moved anything from the scene, except to examine the body, including the syringe that was thrown next to the body. The scene has been photographed and fixed, you can take a look, and if you have any ideas, say them and exchange them. ”

"Isn't this the scene of the '9/16 case', why did Ma Zhichen die in this place?" Huo Yan looked around at the room full of girls' daily necessities and asked curiously.

"According to my speculation, Ma Zhichen may have moved in by himself." Xia Shi replied more confidently. On the night of September 29, Ma Zhichen suddenly ran to the criminal police team and turned himself in, admitted that he had killed He Yao, and asked the police to put him in a detention center. But what happened later proved that Ma Zhichen had nothing to do with the two murders at all, and he actually had another purpose in turning himself in.

"Through interrogation, we have reason to suspect that he has made enemies outside and that his personal safety is under some kind of threat. Although he didn't admit it to his face, his expressions and movements indirectly reflected his heart: he was afraid of something, or rather, he was afraid of someone. We sent him to a detention center for a few days before releasing him this morning because he was obstructing the police case. After leaving the detention center, he probably didn't dare to return to his home, for fear that the enemy would find him to retaliate, so he ......"

So he took the toiletries, a change of clothes and convenience food he bought temporarily and hid in He Yao's house. Gu Song looked at the sports backpacks piled up at the foot of the bed, and continued Xia Shi's words, "It seems that he is really scared, and he doesn't even feel at ease staying in a hotel." Because He Yao's house was a crime scene that was cordoned off by the police, he thought that this place was the safest, and no one could have imagined that he would hide here, and the result was ......"

Gu Song stopped what he was doing, and looked at Ma Zhichen, who had been dead for a long time, with a gloomy expression, feeling very guilty in his heart. "If we had taken this matter seriously and protected him, maybe he wouldn't have been killed......

"No, it's not your fault." Huo Yan comforted Gu Song and said, "After all, the power of the police is limited, you can't protect everyone, and you can't stop all crimes." Now that the murder has happened, it is useless for us to regret it, and the top priority is to find out the murderer. At least judging from the current situation, this case is likely to be related to personal grievances, and we should gain something from starting with the victim's social relationships. ”

"I hope so." Gu Song said with a wry smile. He walked to the side of the bed, carefully picked up the syringe beside the victim, and carefully examined the victim's arm, and his expression suddenly became solemn. "Two needle eyes, one new and one old, has Ma Zhichen started taking drugs again recently?"

"I'm afraid so." Xia Shi replied, "The old needle's eye was left over a week ago. It may be that He Yao's death hit him too hard, and in order to numb himself, he became involved in drugs again, but he lost his life because of it. ”

"Did the syringes and drugs belong to Ma Zhichen, or did the murderer bring them himself?"

"The source of the drugs needs to be further traced, but I think it should have been prepared by the murderer himself, otherwise there is no way to ensure that his murderous plan will go smoothly. Hey, let's not talk about drugs. Xia Shi's focus didn't seem to be on this matter, and he was busy diverting the topic, "You two take a look at that first." Wakanan! He walked to the bedroom door and called, "Bring that evidence bag over here." ”

A few seconds later, Qi Ruonan handed a transparent physical evidence bag to Xia Shi, who took it back to the room, pinched the seal of the bag with his thumb and forefinger, held it up in front of Gu Song and said, "The murderer also left us this." ”

"This is ......" Gu Song and Huo Yan looked at each other, and neither of them understood what the contents of the bag had to do with this case.

The bag contained a small fish about 6 centimeters long with a white stripe on its head, body, and tail. The little fish had been dead for a long time, and it was covered in a layer of slimy liquid, and it looked a little disgusting.

Xia Shi frowned in disgust and said, "This was taken out of the corpse's mouth when Forensic Doctor Chen was examining the corpse, and it was obviously left by the murderer. ”

"Damn, this murderer is perverted enough." Gu Song slurred in surprise, took the physical evidence bag from Xia Shi's hand, and carefully observed the small fish in the bag under the light. "This is a clownfish that lives in tropical marine areas, and it is also one of the most common species of tropical marine fish with high ornamental value, which can often be seen in aquariums, and many fish farmers like to raise this fish at home."

"Isn't this Nemo from Finding Nemo?" Huo Yan asked in surprise, "Why did the murderer stuff this fish into the victim's mouth?" ”

Xia Shi shook his head helplessly and said, "I don't quite understand the murderer's purpose for doing this, so I brought you here." ”
