Chapter 285 The Doubt That Meng Qinghan Discovered (4)
"It's prolactin!"
Wen Sibao didn't understand what the other party was talking about, so he asked: "Team Meng, what is the prolactin you are talking about used for?"
Meng Qinghan explained.
——"Actually, I have been wondering why this mad dog got into the garbage truck."
——"But I suddenly figured out one thing, that is, for male dogs, what attracts them more than food is the urine of female dogs in estrus."
——“Because the urine of female dogs in estrus contains a substance called parahydroxybenzoic acid, which can induce estrus in male dogs in an instant.”
——“The common behavior of male dogs that like to sniff and lick the private parts of female dogs is to use their noses to determine the content of parahydroxybenzoic acid in the female dog’s body.”
——"Although it is not the season for female dogs to be in heat, there is always a medicine containing prolactin in places like veterinary stations."
——"This drug is a powerful aphrodisiac for animals. When used on animals, it will greatly increase the secretion of protein hormones from the animal's glandular pituitary gland, thereby artificially controlling the animal's estrus period to achieve the purpose of breeding."
——"Therefore, the murderer seems to have come full circle, deliberately damaging the monitoring equipment box of the sanitation department and smearing the urine of a female dog in heat onto the brake pedal of the garbage truck.
All just to allow the mad dog to smell the female dog’s urine in heat at the crime scene.”
——“Because the dog’s olfactory mucous membrane is many times wider than that of humans, so after the mad dog smelled the estrous urine in the distance, he would rush into the cab of the garbage truck and lick the brake pedal, eventually causing a car accident.
happened."
——"So the only thing we need to do now is to ask the forensic team to check whether the pedal of the garbage truck contains prolactin. If this can be confirmed, then we can know the identity of the murderer.
All the behavioral logic of this murder!”
During the 40-minute case analysis meeting, at least 90% of the time was spent by Meng Qinghan explaining the logic and methods of the murderer's behavior. At this time, all previous doubts about Meng Qinghan were self-defeating.
Everyone obviously has complete trust in the new captain of the second brigade.
Wen Sibao even wrote down all the clues analyzed by Meng Qinghan in his notebook, and murmured to himself: "There is... an internal smell."
Murong Shui asked in a bad mood: "What does it smell like? Tell me clearly!"
Wen Sibao tilted his head and whispered in the other party's ear: "After listening to all the case analysis of this Meng Qinghan, I feel that there seems to be a feeling of... Xu Tiannan in the other party."
After saying this, Wen Sibao didn't hear Murong Shui's reaction for a long time, and when he turned his head, he realized that he had said the wrong thing.
At this time, Murong Shui looked at Meng Qinghan with hatred, muttering something in a small voice, and her two tiger teeth almost reached an incredible length, as if she wanted to eat the woman in front of her.
General.
Deputy Director Yang was very satisfied with Meng Qinghan's performance today, and then asked: "So Comrade Xiao Meng, judging from your approach, which aspects do you think this case should be investigated from?"
Meng Qinghan responded.
——"First of all, everyone knows that one of the two Wuzhi brothers who escaped this time was the one who escaped."
——"So I suggest that we start with some guest houses and hotels whose registration is not formal enough, and investigate the unemployed foreigners one by one."
——"Secondly, although the sound of the murderer's call to the police was processed, which is what we usually call 'pseudo-sound', I think this call recording can be handed over to experts to process and try to identify the murderer."
When recording this audio, were there any ambient sounds around you that were not easily noticeable?"
——"Third, visit veterinary stations across the city, mainly to investigate the flow of drugs containing prolactin. If the identity of the mastermind behind the scenes can be determined, it will be very difficult to catch the escaped fugitive named Usopp.
It’s easier.”
Deputy Director Yang: "Why do you say that?"
Meng Qinghan said.
——"I checked the history of the Wujue people and found that this ancient nomadic people worshiped ghosts and gods, worshiped heaven and earth, believed in shamans, and even killed their fathers and brothers in an upright duel when there was a suitable reason.
He can be found not guilty."
——"But for such a brave and warlike nation, they have still maintained a consistent external behavior style for thousands of years."
——"Although we don't know what kind of hatred the murderer behind the scenes has with the two Wuzhi brothers, I can't say whether the Wuzhi brothers know who the murderer behind all this is.
"
——"But one thing I can be sure of is that if we catch the murderer behind the scenes, the escaped Usopp's brother will definitely retaliate against him at all costs. Then we will use the murderer behind the scenes as bait. By the way,
Capturing Usopp as well is the most efficient way."
After finishing the conversation, Deputy Director Yang's expression turned from sunny to gloomy, because what Meng Qinghan said was extremely risky and seriously violated the legitimate rights and interests of the murderer behind the scenes.
Although in this set-up, the actions of the murderer behind the scenes almost cost a policeman his life, as a law enforcer, Deputy Director Yang always keeps in mind the boundaries of power given to him by the law. This is also the case as a policeman.
The basic bottom line that must be adhered to.
Therefore, Deputy Director Yang did not adopt Meng Qinghan's last suggestion. At this time, the door to the command room was suddenly pushed open.
When everyone looked around, they realized that the person coming was actually Xu Tiannan.
Xu Tiannan breathed heavily, looked at everyone present, and said without hesitation: "Deputy Director Yang! After my two days of investigation! I think Zhao Luobo's encounter with the two fugitives this time was not an accident, but
There is a murderer who planned all this behind the scenes..."
Before he finished speaking, everyone present looked stunned, because what the other person said now was exactly the same as what Meng Qinghan said when he came in just now. It was as if two people with the same soul spoke it.
words.
But Xu Tiannan seemed very anxious at this time. When he saw Wen Sibao winking at him, he didn't think much about it, but continued to explain to Deputy Director Yang: "Deputy Director Yang, listen to me, this is true!
The murderer deliberately caused the garbage truck to crash into the bungalow after an accident. At the same time, it attracted the attention of our police, which caused Zhao Luobo, who was dispatched at the time, to accidentally meet the Wu brothers. The murderer's real intention was
, is to use the hands of our police to get rid of these two people!"
After finishing speaking, Xu Tiannan looked at the strange expressions of everyone present, then looked at Meng Qinghan, and couldn't help but wonder: "Huh? Did you already know this? Why are you not surprised?"
At this moment, Murong Shui's mind felt as if a heavy hammer had been hit hard, and a sour sense of grievance made her eyes begin to become blurry.
