I originally thought that the old man selling maltose would be an important clue, but I didn't expect to find anything in the end.
Lin Che had been mentally prepared for such a result, because that's how solving a case is, finding clues, eliminating clues, and then looking for the next new clue. But as long as you are careful and patient enough, there will always be a clue that points to the truth.
As a legend of the police force, Lin Che has already solved many major and important cases at a young age. In the national system, he is as famous as his wonderful crime-solving experience for his low-key personality.
Lin Che always pushed aside meetings, reports, and sharings, so there were really not many opportunities to exchange case handling experience with him in private. It was not easy for him to get this opportunity. Su Cheng wanted to arrange for Lin Che and Mu Yang
Have a meal together.
Lin Che declined the offer, but agreed to go back and apply to Wang Ju for a joint special training session.
We don’t have dinner together anymore, but we still need to eat. My colleagues here in Suzhou recommended a noodle soup restaurant, which is just across the street from the Weiming Lake Scenic Area. I parked my car in the scenic area and walked there in five or six minutes.
The noodle soup shop doesn't even have a front door. The outside looks dirty and old, and only locals eat there.
Usually little girls would not like this kind of fly restaurant with no decoration and no service, but just as Lin Che guessed, Mu Yang was not squeamish at all and ate happily. There was only a little soup left in the full bowl.
After the two of them had eaten, they walked into the scenic area from the alley and headed towards the parking lot.
When the sky darkens, the light show prepared for the New Year by the lake also lights up. Colorful neon lights are reflected on the sparkling lake, water lanterns float in it, like twinkling stars, and the entire lake is like a Milky Way tapestry.
When he reached the lake, Mu Yang couldn't help but stop.
"How beautiful!"
Lin Che looked sideways. The person next to her had a small face with a smile. The light from the water lanterns and neon lights fell into her eyes, which were bright and beautiful.
If the entire Weiming Lake was a sea of stars, Lin Che felt that the two brightest stars were Mu Yang's eyes.
From Mu Yang's expression, Lin Che felt the beauty, and the corners of her mouth unconsciously curved at a gentle angle.
Click!
An extremely faint sound came from behind, and Lin Che immediately became alert, turning her head to look for the source of the sound. The tenderness in her eyes instantly disappeared, and she stared sharply at a small shop by the lake.
At the door of the store, stood a woman holding a camera.
"Go over and have a look."
Lin Che opened her mouth and led Mu Yang into the store.
Lin Che was communicating with the proprietress about the secret photography, while Mu Yang was attracted by the various postcards in the store.
This is a mom-and-pop shop. The couple are both photographers. The postcards in the shop are all customized and come in groups. The photos above are their photography works, including landscapes and people. They hang all over the wall.
"I'm sorry, I just saw that the picture just now was very harmonious, so I couldn't help but take it."
The landlady said and handed over the camera. The photo only captured Mu Yang's back and Lin Che's side face. Moreover, because of the distance and poor lighting, the person was very blurry, but the whole picture was extremely beautiful.
"Do I need to delete it?" the boss lady asked.
"No need, please..."
Before Lin Che finished speaking, Mu Yang's urgent voice came from the corner of the store——
"Lin Che! Come and see!"
Mu Yang pointed to a set of four photos on the wall.
In the photo, Jin Kaihao is wearing a dark gray Tang suit, hugging a young woman wearing a light green embroidered pink cheongsam. The two are smiling, talking to each other, and they are in love.
The woman Jin Kaihao held in his arms was none other than Xia Jing!
Lin Che and Mu Yang looked at each other and understood each other's thoughts.
It seems that this trip was not in vain!
Lin Che showed her police officer ID and said seriously, "Hello, we have a few questions about this set of photos that we need your cooperation to answer."
*
The origins of these four photos are not complicated. They were taken casually by the landlady. However, it still took almost two hours to understand the questions clearly. Therefore, it was almost ten o'clock when Lin Che and Mu Yang rushed back to Jiangzhou.
Everyone is waiting for them to come back, including Lao Huang. There are too many clues found today, and they are contradictory. They must be sorted out and analyzed carefully.
Mu Yang asked for the transcript and video of today's interrogation of Xia Jing. Everyone gathered in the big office to analyze the case while she sat aside to complete her psychological analysis.
"Let's go in order, Li Li, younger than you first."
Li Li called Liang Ke, and Lin Che took advantage of Xiao Xiao's time to post a photo of the evidence on the whiteboard, and poured two glasses of water, one for himself and one for Mu Yang, and he leaned next to her.
On another table, looking at Xiao Yu standing next to the whiteboard.
"While searching the master bedroom of Jin Kaihao's house, colleagues from the trace inspection team found a small amount of white powder on the lid of a bottle of lotion belonging to Jin Kaihao's wife, Wang Aiping. After testing, it was determined that the main ingredient was γ-hydroxybutyric acid."
When Yu Yu said this, he looked at Liang Ke.
Liang Ke had already changed into casual clothes and put on makeup. He probably had plans to get off work, but it was delayed because Lin Che and the others came back late.
Liang Ke spoke with professional knowledge: "γ-Hydroxybutyric acid is a class of psychotropic drugs in my country. It is colorless and odorless and soluble in water. Low doses of γ-hydroxybutyric acid can bring about relaxation, enthusiasm and pleasure. Feelings, stimulating desire, and comfortable drowsiness. High doses of gamma-hydroxybutyric acid can cause drowsiness, nausea, vomiting, nystagmus, peripheral vision loss, hallucinations, short-term amnesia, bradycardia, respiratory depression, etc. Side effects can even cause coma and death. According to what Xia Jing described in her confession, the weakness, coma and hallucinations she experienced when she was raped by Jin Kaihao cannot be ruled out as being caused by taking γ-hydroxybutyric acid."
Lin Che frowned and asked, "If Jin Kaihao gave Xia Jing this medicine, why didn't Xia Jing's blood test and urine test detect it the next day?"
Liang Ke handed the physical examination report to Lin Che, "It's not that it wasn't found out, it's that it was ignored."
"Ignored?"
Lin Che turned over the things in her hands and frowned even more. The rape case was a criminal case. How could such an important clue be ignored?
“γ-Hydroxybutyric acid is special and exists in small amounts in the human body. Generally speaking, as long as the concentration of γ-hydroxybutyric acid in urine is less than 10 μg/ml, it is normal. And the human body absorbs and eliminates γ-hydroxybutyric acid.
Acid is very rapid. Research results show that after the human body ingests γ-hydroxybutyric acid, the concentration of this component in the urine will drop to normal levels within 12 hours, and the blood concentration will drop faster.
Until 8 hours.”
Lin Che nodded clearly, "Based on the time, it took more than 14 hours for Xia Jing to go from being unconscious to going to the hospital for a physical examination after reporting the crime."
"Yes, and Xia Jing is young and has a high metabolism. In addition, having sex many times that night also promoted the metabolism of γ-hydroxybutyrate. Therefore, in Xia Jing's physical examination report, the γ-hydroxybutyrate in her body was
The acid concentration is within the normal range."
