Profiler: Crime Scene

The police also learned from the school leaders, teachers and students that this Rebecca usually has a bad reputation.The classmates said that she looked kind and generous, but perhaps because of jealousy, she often provoked the relationship between Sarah and those prominent students behind her back, and it was only after she was exposed unintentionally that she aroused the disgust of the classmates.

The clue provided by Lisa's father attracted the attention of the police, and the suspicion between Rebecca and her boyfriend Torres rose sharply.Although the two had time witnesses at dinner and bars that night, Sarah's death was between 2am and 4am.During this period of time, they have only each other as time witnesses.If two people collaborated to commit the crime, it would not be credible enough.They were arrested at the same time, and the focus of the police investigation also turned to the two.

At this time, the forensic department detected a DNA sample from the lower body of the deceased.The police were encouraged and extracted Torres' DNA for comparison.As long as the evidence detected on Sarah is consistent with Torres, he can be prosecuted.

Unexpectedly, the identification results showed that the two DNA samples were not the same person.

As for the fruit knife found at the scene, because it had been washed with water and treated with disinfectant water, the forensics department used complex reduction techniques to extract a small amount of DNA.After the test, it was found that the DNA sample was detected in the lower body of the deceased, and it was the same person.

It seems that it can be said that if this person is caught, the case can be solved.

Then, the police quickly locked another suspect, Spencer, from the database of persons with criminal records.

The man was a habitual offender with multiple burglaries and one suspected robbery.

The police wanted to arrest Spencer, but when they arrived at his home, they found that the man had absconded and was missing.However, police found a switchblade and a right sneaker at Spencer's home.The sneakers were confirmed to match the pattern of bloody footprints in the bathroom of Sarah's home, and it can basically be determined that they came from the same pair of shoes.Huadu Police Department immediately issued a warrant, and later discovered that Spencer had bought a plane ticket to Mexico.

The police quickly dispatched, arrested Spencer at a remote small airport, and brought him back to Huadu Police Station for trial.Spencer confessed that he used a self-configured master key to sneak into the student apartment that night, just to steal something.Unexpectedly, he found the young and beautiful Sarah who was alone at home.Although he forcibly had sex with Sarah, Sarah was very scared throughout the whole process and didn't yell for help, so she didn't kill her.Besides, he had a switchblade with him, but he never took it out, and he never stabbed Sarah, it wasn't him.

However, the police refused to believe his confession. Sarah had obvious beating scars on her body, his DNA was detected in her body, and the bloody footprint in the bathroom was also confirmed to be from Spencer, as well as the fruit knife. He can hardly deny the detected DNA.

Spencer argued that after having sex with the deceased that night, he was looking for belongings in the apartment when he suddenly heard two people talking outside the door and heard them holding the key to open the door, so he had to break the window glass and turn out the window.Maybe I was too flustered at the time, so I dropped a shoe, and didn't pay attention to where it fell.

After Joseph saw this detail, he attached great importance to it. He suspected that the people who came back were Rebecca and Torres, and immediately called the police for detailed inquiries.

At this time, the forensics department verified Spencer's switchblade and found that it did not contain any DNA of the victim.

Spencer repeatedly recalled the scene at that time, and said with certainty that the two people who came back were a young man and a woman. At that time, it was about one o'clock in the morning.

Both Rebecca and Torres have denied being at the crime scene that night.

However, these clues provided by Spencer aggravated the police's suspicion of the two of Rebecca.The police quickly expanded the scope of the search and offered rewards for clues.

Someone anonymously reported that they had seen Rebecca and Torres in a supermarket near the student apartment.

The police immediately conducted a large-scale search, checking small supermarkets within a few kilometers of each other one by one.

A few days later, an important piece of evidence was discovered.On the night of the incident, the video of a community supermarket about two kilometers away from the student apartment showed a passing car. The driver and the person in the passenger seat were Torres and Rebecca!

When the police took out this video and played it in front of Rebecca and Torres, there was a completely different reaction.Rebecca said nothing, but Torres was extremely flustered.

The police conducted a carpet search of the crime scene again and found a button that had fallen under the sofa.Immediately, the police discovered that the button came from a two-piece pajamas worn by Sarah.Then, the police detected a semen sample from Torres from the button.

Torres was immediately arraigned by the police, but he argued that he had pursued Sarah before, and that after meeting Sarah again at Rebecca's house, the two had been in private.

The police officer who was in charge of the inquiry asked him why the two of them had returned to the apartment that day, why they didn't call the police, and afterwards concealed that they had been at the scene of the crime that night.

Torres argued that as soon as he and Rebecca returned to the apartment that day, they found that Sarah had been killed and someone had escaped through the window.They drank a lot of alcohol and drove. They were afraid of being sued by the police, and even more afraid of killing people. In a panic, they ran away without thinking.The police came to the door the next day, and the two dared not admit it.

The case was at a stalemate for a while, whether the murderer was Spencer, the thief who burgled and stole the sheep, or Rebecca's boyfriend Torres, or conspired with Rebecca, the police had different opinions.

Joseph asked Lu Yuanli for help. Lu Yuanli thought for a while and said, "I still feel that the fruit knife found is not a murder weapon, and it was treated with disinfectant, which is deliberately misleading the police. If it is Spencer, it seems that he does not have the ability and brains to do this , he didn’t even throw away the one sneaker heel switchblade left, and women are better at using disinfectant and things like that.”

This means... Joseph paused, "But there is no evidence so far."

Lu Yuanli said: "There is not much difference, right? Based on the existing evidence, the supermarket surveillance proved that the two appeared nearby. Torres also admitted that they had been to the scene of the crime, and there was also the semen found at the scene. Even if they If you don’t admit it, there are enough suspicions and motives. You can prosecute them at the same time, see the reaction, and at the same time, check the scene of the crime again, I think, maybe there will be new discoveries.”

Joseph called the police again to conduct a more detailed screening, but nothing was found.However, during the autopsy again, a certain amount of skin tissue was extracted from the crevices of Sarah's nails.

Several police officers reappeared in the interrogation room.When Rebecca saw the handsome young man who walked in at the end, she couldn't help but froze, "Professor Thomas..."

Lu Yuanli smiled and said: "You and Sarah, have you attended my class together? Then you can be regarded as my student. I think you should know what I do. Rebecca, why don't you just say , don’t make me ask, please? Everyone saves time.”

Rebecca frowned and said, "Professor, I don't know what you're talking about..."

Lu Yuanli said: "Then do you know that Torres and Sarah had sex on the night of the incident?"

Joseph and Jiao Yang looked at each other, this is a fraudulent confession!Torres only admitted that he had an affair with Sarah.Because Torres' semen was not collected in Sarah's body, and the pajama buttons were found at the scene many days after the crime, it is impossible to accurately determine when they had a relationship.In fact, if Torres is calm enough, it can be completely denied.

Rebecca was startled, "No, I don't know..."

Lu Yuanli smiled and said: "But Torres has already admitted it. You also know that when you returned to the apartment together that night, you were accidentally captured by a nearby surveillance video. Moreover, the police added some new evidence. Sarah's body at the scene of the crime Torres' semen was found on a pajama button. Can you explain why you didn't know about it?"

Rebecca said in embarrassment: "I, I was too tired, I fell asleep when I got home..."

very good.Joseph, who was sitting behind the monitor, looked at Jiao Yang, which was an admission that they went back to the apartment together that day.

"You're lying." Lu Yuanli said with a smile, "You've been dating Torres for almost two years, but the relationship has always been up and down. Torres is playful and often wanders between several women. Although you are his outsider The public girlfriend, he never stopped, Lieyan's footsteps. You take Torres back to the apartment, only to find that his attitude towards Sarah is wrong.

After you questioned, you found out that Torres had secretly pursued Sarah.This brings you deep anxiety that Sarah will snatch Torres away.You come back to the apartment late at night to find someone burglarized and sexually assaulting Sarah.Not only did you not call the police and rescue the unconscious Sarah, but Torres took advantage of the thief who had beaten Sarah before, and when she was terrified and unconscious, sexually assaulted Sarah again.

You have been friends for many years, but because you have been jealous of Sarah, you don't stop it.However, in the process, Sarah woke up.She doesn't know the thief, but of course she knows you, and as long as she calls the police, it will be over for you all.Torres subconsciously pinched her neck, but you picked up the table knife next to her and stabbed her in the chest..."

"no!"

Rebecca screamed: "That's not the case! Torres raped people, not me, why should I kill Sarah?!"

"I said it because of jealousy."

Lu Yuanli said coldly: "Sarah is a flower in the Department of Foreign Languages ​​and has many suitors. You are just an inconspicuous follower by her side. She doesn't like Torres at all. Torres is just an idiot with only appearance. Torres has always treated Sarah La kept thinking about it, and took the opportunity to get Sarah. You were so jealous that you simply wanted to kill Sarah and plant it on the escaped thief."
