¡°Brother Xian, can you deduce the brand from the chemical composition of nail polish?¡± I asked next.
"The pigment content in nail polish is low, and the content of phthalates and formaldehyde seriously exceeds the standard. Therefore, this nail polish should be produced by a small workshop. It is estimated that it is the kind sold at night markets for five yuan a bottle. It cannot be Determine the brand characteristics." Lao Xian said while pushing up his glasses.
"It seems that the suspect's living standard is not very high." I replied with some disappointment, and then opened the on-site investigation record book. "The fingerprints have no lines. Apart from being able to determine gender, they basically lose the ability to compare. value. But through the distribution of fingerprints and shoe prints, I analyzed that the suspect was quite familiar with the situation in the deceased¡¯s home, and the order of her crimes could be judged from the shoe prints. She should have directly turned over the middle door in the bedroom after the murder. wardrobe, then went to the kitchen and opened the refrigerator.¡±
"It's possible that she was searching for food in the refrigerator, but the purpose of searching in the closet was very clear. There was a green iron safe hidden in the closet she opened. In other words, could her motive be to steal property?"
"She only touched the middle wardrobe and didn't move anything else?" Fat Lei asked.
"Yes, her goal was very clear, she went straight to the closet in the middle."
"The suspect has the key to the deceased's home and knows the location of her belongings. It seems that the relationship between her and the deceased is very unusual!" Fat Lei said something else - there is no doubt that an acquaintance committed the crime.
¡°That¡¯s all I have here for the time being, Brother Xian, please continue.¡± I closed the survey record book.
Lao Xian took over: "There are only two kinds of physical evidence that I extracted at the scene. One is nail polish, which I have just mentioned; the other is what I extracted from the closed trash can in the kitchen. The amount is It was large, with broken glass."
"This is an organic substance. Its physical form is a light yellow viscous liquid, acidic, with a pH value of 3.9 to 4.1. Part of it is soluble in water, and the rest will form a suspension with water. It is partially dissolved in alcohol and partially precipitated; it is partially dissolved in alcohol and partially precipitated. All dissolved in hydrochloric acid or sodium hydroxide. The organic ingredients mainly contain protein, fat, sugar, vitamin A, vitamin b1, vitamin b2 and rich folic acid, pantothenic acid and inositol. Through these data, I analyzed that this light yellow sticky The liquid should be royal jelly.¡±
¡°Royal jelly?¡±
"Yes." Lao Xian continued, "There are water droplets suspended on the glass fragments in the trash can, and the liquefaction phenomenon is obvious."
When Lao Xian said the word "liquefaction", I already roughly understood what he meant. "Liquefaction" is no stranger to everyone. It is common sense in high school physics. The "liquefaction" phenomenon on the glass fragments that Lao Xian said actually proves that the large jar of royal jelly was taken out of the refrigerator and dropped into the trash can. The temperature of the glass bottle taken out from the refrigerator is relatively low. When the water vapor in the air is cold, it will turn into liquid water and condense on the outside of the bottle. This is just a simple physical phenomenon.
Lao Xian then analyzed: "Because it was difficult to extract on site, I took everything in the trash can back to the laboratory. The glass bottle has been restored by me. Through calculation, the total capacity of the entire glass bottle is 500 ml, and the royal jelly The total volume is also close to 500 ml, which means that the glass bottle that was smashed in the trash can was full before. Through composition analysis, this bottle of royal jelly is very fresh and an original ecological product. According to the price on the market After all, this bottle can be sold for nearly 500 yuan."
From the current point of view, this expensive bottle of royal jelly may have been thrown by the suspect into the trash can. The phenomenon of venting anger is obvious. This shows from another aspect that there may be some kind of hatred between the suspect and the deceased. This kind of hatred It was most likely one of the motives for the murder.
"Have you found anything else?" Brother Ming continued to ask after recording.
Lao Xian closed the report and shook his head.
"Ye Qian."
"Director Leng, tell me."
¡°Ask the criminal police team to bring the deceased¡¯s son over, and I will ask him personally.¡±
"clear."
Our current conclusion is that the suspect and the deceased knew each other well and knew the location of the property in the deceased¡¯s home, and there may have been hatred between the two. To unlock the answers to all the questions, asking the son of the deceased is the most direct way. (Remember the website address: www.hlnovel.com
