"I went to Sister Dunyue's house and sprayed the living room and yard with luminol spray, and there was a fluorescent reaction."
"You mean, someone was injured? Is it serious?" Li Sen naturally knew what Luminol was, and his heart was twitching.
"I'm not sure whose blood it is at the moment. We'll have to do a test to find out." Ouyan explained, "I sprayed the spray and dipped a cotton swab into the dirt and dust on the fluorescent surface. The results will be available in a while. In addition, I was in the month.
Hair strands were found in the rooms of my sister and her parents, and there were nails cut by someone who didn’t know who was in the corner and under the sofa, so I collected them all.”
DNA can be extracted from nails and hair, but if too much time has passed, the extraction may not be successful.
When the blood stain test results come out, and then compare their DNA, you will know whether it is their blood.
If it is their blood, it means that they were injured at home before. The living room was the first crime scene, and then they were moved to the yard, which is the second scene.
But if not...
Li Sen's heart clenched violently. Why were Yueyue's parents involved? How much was behind this matter that they didn't know?
"Oh, by the way, boss, these are the hairs of those people inside." Dahei brought several transparent small bags to Ouyan, and there were still some blood stains inside.
"How much did you collect?" Ouyan took the small bag, blood and hair, and DNA could be detected.
The blood in Sister Yue's living room and yard may also be from the four people inside...
Ou Yan took out another small transparent bag from his backpack. There was only a little powder in it. If you didn't look carefully, you would have thought it was an empty bag.
"What is this?" Li Sen asked again.
"This was found in the vitamin C bottle in Sister Yue's room."
Dahei on the side was a little confused, "Isn't vitamin C always in pieces? Why is it in powder form?"
"This is not vitamin C." Ou Yan said this and looked at Li Sen, "One of the ingredients in this powder is dragon grass."
Dragon grass?
At this time, Li Sen could no longer remain calm, his heart seemed to be clenched tightly, and he was almost suffocated by pain.
"What is dragon grass?" Dahei has been with the boss for many years and has never heard of it, but judging from the reaction of the third young master, it seems that it is not a good thing.
Li Sen knew that Dragon Soaring Grass is a powerful poison. "You mean, Yueyue took the poison? The person... is probably dead??"
"Not necessarily." Ou Yan said softly, "Longteng grass can also be used as medicine. It mainly depends on the other ingredients. Third brother, don't worry too much. Dahei, you take third brother to have a rest. I will go to the experiment first.
room."
"Yes." Dahei said with a gesture, "Third Young Master, please come this way."
Li Sen didn't know how he walked into the main building. The place was magnificent. Whether it was decoration or furnishings, it was no worse than Bianhu Villa. But now he was in no mood to look at the surrounding environment. He was thinking about what his sister had said.
if.
Dahei changed his clothes and came out, holding a lot of food and drink in his hands.
"Third Young Master, please eat something first, or you can drink some tea. Let me tell you, only our boss drinks this tea, and no one else can drink it..."
Dahei smelled the tea fragrance in the air, it was so fragrant.
