Fingerprint Clues [3]

There was a sound of a car engine, and a black Mercedes-Benz slowly stopped near the house.
The door opened, and Li Ze got out of the car first.
Yang Fei also got off the co-pilot carrying a schoolbag. The backpack was filled with some of his professional computer equipment.
“Captain Li!”
The police officers at the door all saluted Li Ze.
Li Ze nodded slightly, then led Yang Fei into the house where the crime happened.
Although Yang Fei is a member of the technical team, it is also necessary to let him get in touch with the case handling process and increase some relevant criminal investigation knowledge, so that the handover of some work tasks will be smoother.
Walking into the house, the police officers were conducting surveys in every corner of the house.
“Teacher Li.”
Hao Wei greeted Li Ze, then pointed to the bathroom beside him and said, “The body of the deceased is in the bathroom.”
Li Ze nodded, and then came to the bathroom on the first floor. A naked corpse was lying in the bathtub. There were dozens of stab wounds on his body, and the wounds were soaked in water and swollen.
The forensic doctor Yang Ming on the side took off the mask on his face and said to Li Ze: “The time of death of the deceased was four to six hours ago, that is, around one or two o’clock in the morning today. There are a total of 23 places on the body. The stab wound, the fatal wound is at the heart, the lower body is torn, and there are traces of multiple xing attacks.”
Yang Ming looked at the corpse beside him and sighed, “She’s still a little girl… How could the murderer bear such a cruel hand?”
Li Ze also observed the body of the deceased, and said slowly, “The knife wounds on the deceased’s body are messy, different in depth, and almost stabbed at random, which shows that the murderer is not skilled in the use of knives.”
“Has the identity of the deceased been investigated clearly?”
Li Ze turned to look at Hao Wei beside him.
“The investigation is clear.”
Hao Wei nodded and said, “The deceased’s name is Xue Liyuan, a second-year high school student at City No. 2 Middle School, who just turned sixteen this year.”
“Sixteen years old…”
Yang Fei, who was beside him, also looked ugly. He was not very old himself, so he hated the murderer’s actions on underage girls.
Li Ze observed the body for a while, and after finding no clues for a while, he left the bathroom and went to the second floor.
The door of a bedroom on the second floor was directly open, Li Ze walked in, and then saw the LV bag on the bed.
Li Ze put on gloves and opened the LV bag. There were basically some cosmetics, wet wipes and the like inside. In addition, there was a brand new fruit XS phone with a pink casing.
“I’ll give it to you. Unlock the phone.”
Li Ze handed the phone to Yang Fei who was beside him.
“no problem.”
Yang Fei took the phone, immediately put down the backpack behind him, took out the corresponding laptop, and then connected the phone to the computer through the data cable.
Li Ze continued to rummage through the bag for a while. After finding no other clues, he suddenly turned to Hao Wei beside him and asked, “How is the family of the deceased?”
“generally.”
“generally.”
Hao Wei replied, “Her parents are doing some small business in a foreign city. She is alone at home on weekdays. The family conditions are average. You can tell by the decoration environment of her house.”
Li Ze also nodded, then looked at the LV bag on the bed and said, “The family conditions are average, but I wear a LV bag, use a fruit XS mobile phone, and the cosmetics in the bag are all genuine brand goods. It’s like the configuration of a rich lady.”
“Check to see if she has any special relationships on weekdays.”
Li Ze said slowly: “If his family didn’t dote on her very much, then she might have been taken care of.”
“At such a young age…”
Hao Wei sighed and did not continue.
Yang Fei, who was beside him, unplugged the data cable from the phone, “Boss Li…the phone lock is unlocked, but the phone seems to be broken, and the hardware inside is badly damaged.”
Yang Fei took off the phone case from the phone, and the back glass cover of the phone apparently fell into a spider web shape. It was impossible to see it with the phone case on.
Li Ze took the phone, and the back cover really fell very badly. He tried to check the call records and text messages of the deceased, but found that there was no data in it.
“Leave this to the technical team and let them find a way to restore it.”
Li Ze put the mobile phone in the evidence bag and handed it to Hao Wei next to him.
He knows that such hardware damage is more troublesome to deal with. If it falls seriously, it is highly likely that it cannot be recovered. Even if a small part of the data can be recovered, it is quite time-consuming, so he chose to let the technical team go.reason.
“OK.”
Hao Wei took the evidence bag and nodded.
“When I entered the door before, I noticed that there were cameras at the intersection outside the door, so I went to tune up the surveillance video at the door last night.”
Li Ze instructed a police officer beside him.
“learn.”
The policeman nodded immediately and agreed.
Li Ze continued to search the house for a while, but a police officer suddenly ran upstairs and said to Li Ze, “Captain Li, we have extracted a complete fingerprint on the door handle!”
Hearing this, Li Ze was also shocked. Fingerprints are relatively convincing evidence, which is usually very helpful for the progress of the case.
“Immediately hand over the extracted fingerprints to the technical team and let them pair the fingerprint database.”
(Wang Lihao)
Li Ze said.
Although the fingerprints have been extracted, it does not mean that the corresponding murderer can be found quickly. Fingerprint matching is a very complicated and tedious process, which takes a lot of time.
It is obviously impossible to match the fingerprints of more than one billion people in the country. Usually, the matching work only matches the criminal suspects who have left a criminal record, as well as the relatives and friends of the victims.
Specifically, it is still up to the police to screen out a certain number of suspects through various clues for matching, and then determine the corresponding murderer.
