While Zhang Hui was interrogating Qin Jun, the Provincial Technical Identification Center also returned the identification and analysis results of the trace evidence on the first corpse.
In the current exploration laboratory, Lu Chuan, Yang Sen, and Lao Bai are analyzing.
"Cosmetics... Dabao sod honey?" Yang Sen frowned: "This is something only men use. Women rarely use this kind of cosmetics, right?" Lu Chuan wiped the cosmetic residue on the face of the first corpse, The identified ingredient turned out to be a cosmetics brand often used by men.
"The material of the tape is just ordinary wide transparent tape, there is nothing special about it."
"The skin flakes and dirt in your nails belong to you."
"But these hairs...Angru ferret?" The hairs found on the first corpse were also found by Lu Chuan on the second corpse.
Although the trace evidence test results of the second corpse have not yet come out, the two colors react the same under the strong light of the horse lamp, and they should belong to the same type of hair.
Lu Chuan originally guessed that this might be the hair of cats, dogs and other pets, but he did not expect that it was the hair of Anglo ferrets.
"What is an Anglo ferret?" Yang Sen looked at the words on the report and had never heard of it. Lu Chuan knew, because Lu Yao had one: "Anglo ferret is a kind of pet ferret, which has become more popular in recent years." Strictly speaking, the Anglo ferret should be regarded as a kind of skunk. They have well-developed odor glands and will fart when frightened.
It’s just that pets from formal breeding channels have all undergone deodorant gland surgery. This kind of ferret likes to be clean like a cat, likes to curl up to sleep, has a relatively high IQ, likes to be close to people, and like a dog, likes to follow its owner.
It is a popular pet that combines the cleanliness of a cat with the loyalty of a dog.
"The price of this kind of pet is relatively expensive, especially for some with good fur color. A pet mink can cost tens of thousands of yuan." Lu Chuan once heard from Lu Yao that there was a group of pet minks in Haizhou City who kept this kind of pet mink. mutual communication.
"My cousin has a mink at home. I'll ask him later to see if I can find anything." When Lu Chuan called, Lu Yao was playing with the mink in the security room at the entrance of the community.
"There are no factories that breed pet minks in Haizhou. All the ones we buy are imported."
"There are not many people who keep this thing. There are only about a hundred or so people in our group." One hundred people... Anglo ferrets are not a particularly common pet. There must be ferret hair on the dead body. Have had contact with this ferret either during life or after death.
Generally speaking there are two possibilities. Either the person who was killed had the ferrets himself, or the murderer had the ferrets.
But no matter which one, the investigation scope of the naked corpse case can now be targeted at this group of more than 100 people.
Of course, it is impossible for everyone who breeds Anglo ferrets in Haeju City to join this group. Just like the car enthusiast group, in addition to Cadillac car enthusiasts, there must be many car enthusiasts from other brands who are not in the group.
Room inquiry. Qin Jun's face turned pale with fright, and his hands couldn't help but tremble: "Police... police... police officer... you, you... you... what are you talking about... dumping the body?!" Bang!
Zhang Hui slapped the table with his palm, and the loud sound made Qin Jun tremble again.
"Qin Jun! Look at this photo!"
"You won't forget this blue paint bucket, right?"
"No... I haven't forgotten. When I set fire to the files, I used... the gasoline in this bottle."
"As long as you haven't forgotten, tell me where this bucket came from!" After Qin Jun was arrested, his fingerprints were collected.
But they were compared with the fingerprints on the bottom of the blue paint bucket and the fingerprints on the ankles of the second body.
The result is that Qin Jun is not the owner of these two fingerprints. In other words, although Qin Jun used a blue paint bucket, he did not kill anyone.
"Picked up...picked up."
"Picked it up? Where did you pick it up?"
"I picked it up from the trash can. On the day of the arson, I picked it up from a trash can near the Friendship Hospital on Huaguang Street." Qin Jun was frightened to death by Zhang Hui's talk about throwing corpses. He explained that he was pouring beans out of a bamboo tube: " I was afraid that the arson would be discovered, so I wore gloves at the time."
"After I drained the gas out of the car, I set it on fire."
"Really, officer, that bucket is not mine, I really picked it up!" In the office next door, Qin Yong rubbed his temples with a headache.
It was originally thought that with the discovery of half a fingerprint, the suspect Qin Jun was identified, and the case might be solved.
But in fact, Qin Jun is indeed not a suspect. He had been at home for the past two days and had an alibi for dumping the body.
And he also explained the origin of the blue paint bucket.
"First go to the place where he picked up the paint bucket and take a look." Sun Jun expressed his opinion: "The fingerprints on the ankles of the second corpse should have been accidentally left by the murderer while tying the tape."
"The fingerprints on the bottom of the paint bucket are identical to those found on the deceased, which means that the person who discarded the paint bucket is probably the murderer."
"I asked someone to check and found that the paint bucket contained latex paint, which is a decoration and building material."
"Since the other party discarded the paint bucket near Friendship Hospital, is it possible that the murderer's home was renovated nearby?"
"Or is the murderer a decoration worker?"
"It's been three weeks since the arson case. If it was really decoration, it shouldn't have been completed in three weeks, right?" Qin Yong nodded. Sun Jun's analysis made sense.
There is a high probability that the owner who discarded the paint bucket is the murderer.
"Does anyone else have any ideas?" Everyone looked at each other, then shook their heads. Qin Jun told him the location where he picked up the paint bucket, so he must use this place as the center to investigate the surrounding area.
Sun Jun's reasoning and guessing are already relatively detailed.
"Team Qin, we still have some discoveries here." Liu Guodong opened the office door and handed him the trace evidence analysis report of the first corpse.
"The results of the trace evidence analysis on the first corpse have come out."
"The cosmetics on the corpse's face are Dabao brand sod honey often used by men."
"This shows that the murderer is likely to have imprisoned the deceased for a long time. Otherwise, the cosmetics brand used by women should be detected on the corpse."
"In addition, the fine hairs found on the body were identified as the fur of a type of pet called Anglo ferret."
"Not many people breed this kind of ferret in Haizhou City. They also have an exchange group with a total of ninety-eight people."
"I suggest that during the investigation, we should focus on these people." Qin Yong was in high spirits after listening to Liu Guodong's report.
The findings of the current survey office have once again narrowed the scope of the investigation.
"Okay, next our focus is to conduct a large-scale investigation centered on the Friendship Hospital, focusing on the nearby Ange..." Unable to remember the name of the mink for a while, Qin Yong looked at Liu Guodong.
"Anglo ferret."
"Yes, focus on the people who raise Anglo ferrets!"
