Shangguan Feng suspected that Yu Yue had ulterior motives. Her face turned cold as she said,"Don't you think the possibility of the murderer staying in the same place after killing is very small?”
Yu Yue smiled." Those people often deal with the police. They have a strong sense of anti-reconnaissance. They should know very well that leaving immediately after killing will easily attract the attention of the police."”
"What do you have in mind?" Shangguan Feng asked.”
Yu Yue whispered. Shangguan Feng frowned and said,"This is simply nonsense. No!"
"I really want to help. I don't want this simple case to waste everyone's time."”
Shangguan Feng frowned slightly. After thinking for a moment, she said,"Alright, how confident are you?"
"Sixty percent is enough for me to take the risk," Yu Yue said.”
"Don't be afraid, I know what I'm doing," Yu Yue said confidently.”
Shangguan Feng stared at Yu Yue for five seconds before she slowly said,"If you think that your bravado will change my impression of you, then you are very wrong.”
"Don't worry, if you fail, I won't bother you anymore." Yu Yue smiled.”
"Good!" Shangguan Feng said decisively. Deal! I'll arrange it for you now!"
After a while, the forensic doctor arrived at the scene and quickly confirmed that the victim had drowned. He was looking for the cause of the drowning. Outside, Yu Yue's plan had already begun to be implemented.
After a round of investigation, almost half of the male customers had left the bathhouse. They had left their identities, addresses, and other information, and they had a more credible alibi.
Seeing people leave, some people could not sit still anymore. They complained and strongly requested the police to let them go home as soon as possible. A few high school students even said that they had exams the next day and had to go home as soon as possible. Their parents had already come to the door to wait when they heard the news.
" Everyone, don't be anxious," Yu Yue said,""We will get the innocent people home as soon as possible.”
"How much longer will it take?" someone asked.
Yu Yue said," Very soon. It will only take about five minutes. The forensic doctor just brought us a new discovery. It is obvious that the murderer left a flaw. As long as everyone is patient and cooperate with our work, we will soon find the murderer and go home happily."”
"Tell me, how do you want us to cooperate?" someone asked.”
"Everyone, please face me and form two rows…" Yu Yue said.
Everyone quickly lined up in front of Yu Yue. Yu Yue said,"Now, let's invite our criminal investigation team members to spray some special chemicals on everyone's feet..."
Xing Tianyu and the others held a watering can and wore masks to spray the liquid on the calves and feet of the customers of the bathing center.
Everyone looked at him in confusion. A burly man with a tiger tattoo on his arm said,"My skin is very sensitive, so there's no need to spray it, right?”
"Don't worry, this medicinal liquid is very gentle. It won't hurt your delicate skin."”
Everyone chuckled a few times. Then, someone asked,"Officer, what's the use of spraying this medicine? Can it detect blood stains?"
"No, it can't be used for blood tests. It's used for urine tests."”
"A urine test?" Everyone was puzzled.
Everyone immediately shut up, and the bathing center became quiet.
Xing Tianyu and the others continued to spray the medicine at the feet of the people in the line. Yu Yue continued," Now, I can tell you why we have to test your urine on your feet. This is because when a person is about to die, their body is tense, and there are often signs of forced defecation and urine…"
Someone could not help but laugh. Yu Yue glanced at them and continued,"According to the forensic examination, the victim urinated before he died today. His urine must have stuck to the person beside him, which means that it stuck to the suspect…Don't look down, look at me…"
" I don't know if you've heard or seen it before," Yu Yue said." Many public swimming pools use a reagent. As long as someone pees in the pool, the water will quickly react and turn blue. This will expose those who don't follow the rules…"
" The reagent we used is similar. Because the suspect may have been soaked in water or even bathed for a long time, there is less urine left on his body. It is a micro-mark reaction. After the reagent is sprayed, it will take three to five minutes for it to appear. Now, someone's feet have begun to change color."
Someone started to look a little uneasy. The student who said that he would have an exam tomorrow raised his hand and said hesitantly," Officer…I…I couldn't help but…pee in the water when I was taking a bath…"
