The hard-working and simple Zhang Jiwen in Yimeng Mountain in the past, after experiencing social and realistic beatings, became Zhang Xiuwen, who can perfectly design and kill, which is not an unacceptable strange thing.

Ma Hongwen was thinking about what kind of means and ways to open a breakthrough from Zhang Xiuwen, but the old forensic doctor came over and called Ma Hongwen, asking him to go to the forensic office in person, and said that he would definitely regret it if he didn't go.

Ma Hongwen was handled very well by the old forensic doctor, and when he heard such a rumor, he rushed over without saying a word.

The old forensic doctor picked up a finger bone on the plate with tweezers, and then used another tweezers to remove a gold ring from the bone, and pointed the inside of the ring to Ma Hongwen.

"There are three words 'Wang Wenhui' in this ring, do you see it?" The old forensic doctor asked as he moved his hands.

Ma Hongwen looked at it fixedly, and when he saw that this was indeed the case, he nodded and asked with doubt, "What is the situation?"

The medical examiner put the ring back on the bone and put it back on the plate: "This is what your people found in Wang Yuan'e's bedside table. At first, they thought it was a plastic prop, thinking that someone who was full of food and had nothing to do would put a real person's finger bones in their bedside table, so they didn't take it seriously, took one look at it and stuffed it back into the bedside table."

"Thanks to your always suspicious character, we arranged for us to expand the scope of testing at Wang Yuan'e's house, and do a second trace check on his house from the ceiling to the bathroom sewer."

"No new traces were detected, but your people muttered in the process, saying that Wang Yuange's hobby of collecting is a bit unconventional, in addition to calligraphy and painting antiques, he actually likes to collect human skeleton props."

"I asked casually, and I found out that Wang Yuan'e actually hid such a thing in his bedside table. I knew it was a real human bone, not a plastic prop, so I brought it back for further testing."

Ma Hongwen frowned, still puzzled: "The ring on this finger bone is engraved with 'Wang Wenhui's name, does it mean that the owner of this finger and ring is Wang Wenhui, or is it Wang Wenhui's spouse Ruan Xianglan?"

Wang Wenhui wears a ring with his name engraved on it, which is a possibility. At the same time, it is also possible that Nguyen Heung Lan was wearing a ring engraved with her husband's name.

"I think so too. Therefore, if the DNA of the finger bone and Wang Yuan'e's corpse is compared, as long as the DNA match between the two is successful, proving that there is a father-son or mother-son relationship between the finger owner and Wang Yuan'e, then it is very likely that the owner of the finger and the ring is Wang Wenhui or Ruan Xianglan."

"But guess what?"

The corners of Ma Hongwen's mouth twitched a few times involuntarily, he knew that since the old forensic doctor asked so, it would definitely not be the answer he imagined.

Seeing Ma Hongwen's constipated appearance, the forensic doctor couldn't help but pat him on the shoulder, and said helplessly, "You guessed it, the DNA results don't match at all. In other words, from a biological point of view, Wang Yuan'e and the owner of the finger wearing the ring are completely unrelated people. This case really gets more complicated the further down you investigate."

"Are you saying that the owner of the finger and ring is not Wang Wenhui or Ruan Xianglan?"

The medical examiner grimaced: "If that's the case, this case isn't that complicated. Maybe Wang Yuan'e really has a perverted hobby of collecting human bones, which would explain why he found this thing on his bedside table."

"The problem is that I compared the DNA of my finger bones with one of Wang Qianshan's children, and the results were matched. In other words, the owner of the finger bone is most likely Wang Wenhui or Ruan Xianglan."

Ma Hongwen finally sorted out the underlying logical relationship: "You mean that there is no blood relationship between Wang Yuange and Wang Wenhui, and he is not the biological son of Wang Wenhui and his wife?"

"It's complicated."

"If the owner of the finger bone is Wang Wenhui, and Wang Yuan'e and Wang Qianshan are half-brothers, that is to say, Wang Yuan'e's mother is Ruan Xianglan, but his father is not Wang Wenhui, then there will also be this result after we do DNA comparison now."

"That is, Wang Wenhui's DNA cannot be matched with Wang Yuange, but it can be successfully matched with a pair of Wang Qianshan's children."

Ma Hongwen was even more puzzled: "You mean, Ruan Xianglan actually dares to plant grass on Wang Wenhui's head?"

"I had your doubts at first. Therefore, Wang Yuan'e and Wang Qianshan's children have made a horizontal comparison in DNA, as long as Wang Yuan'e and his nephews and nieces can successfully match in DNA, then this hypothesis will be valid. As a result, they still don't match."

Ma Hongwen gasped: "In other words, on the premise that the owner of the finger is Wang Wenhui, Wang Yuan'e is not related to any of Wang Wenhui and his wife. On the contrary, on the premise of assuming that the owner of the finger is Nguyen Heung Lan, this result is still true."

"This means that there is no parent-child relationship between Wang Wenhui and Wang Yuan'e at all, and Wang Yuan'e is not born by either of them?"

Ma Hongwen seemed to remember something: "The underlying premise of our conclusion is that Wang Qianshan is indeed the biological child of Wang Wenhui and his wife, and the logical condition that Wang Wenhui and his wife, Wang Qianshan and their children are the exact immediate family members. Is it possible that in terms of blood relationship, it is Wang Qianshan who has the problem, not Wang Yuan'e?"

Ma Hongwen means that it is possible that Wang Qianshan was not born to Wang Wenhui and his wife.

The forensic doctor looked at Ma Hongwen with the eyes of an idiot: "Then the DNA of this finger bone should not match Wang Qianshan's children."

Ma Hongwen spat on his face, without shame: "I am making a bold assumption...... Be careful to verify."

The forensic doctor snorted coldly: "You still go to the bedside table of Wang Yuan'e for headaches, why is there such a finger bone?"

Then, he pointed to the bone with tweezers: "You have a lot of headaches, not just this one, let's do it one by one."

"Judging from the bone density, the age of the finger bone owner should be about 45 years old, which is exactly the same age as the age when Wang Wenhui and his wife died seven or eight years ago."

When Ma Hongwen was interrogating Zhang Pei, he accidentally learned that Wang Wenhui and his wife were most likely to die on the same day. After the interrogation, subordinates were questioned about this issue. The investigators immediately contacted the local police station and the community where they were located, and learned that in 2001, Wang Wenhui and his wife died in a fire that broke out in their home at the same time.

The old forensic doctor, who always pays attention to the progress of the case, will naturally know this.

"The bigger question is, since Wang Wenhui and his wife died in the fire, how did such a well-preserved finger bone come from? I examined the entire finger bone and found no signs of burning."

Ma Hongwen understood it at a glance: "In other words, this finger bone should have been taken down before Wang Wenhui and his wife were buried in the fire."

The forensic doctor nodded, flicked the bone with tweezers, aimed the bottom of the finger bone at Ma Hongwen, and stopped the tip of the tweezers at the bottom of the finger bone: "See? The bone spurs were jagged and the incision was smooth, which was clearly cut by a sharp knife or axe."

Ma Hongwen's little eyes narrowed involuntarily, and he muttered, "In other words, the fire that killed Wang Wenhui and his wife is very likely to be a man-made murder, not some bullshit' sudden safety accident."

"What the hell is going on, that's your business. I will only tell you the objective facts that I can be sure of."

The medical examiner then rested the tip of the tweezers on the gold ring: "Gold does not turn black if it is not eroded by foreign objects. But there were a few small black spots here, and after careful examination, I found that it was the corpse of a small insect. That is, the dried corpse of the insect, the tissue of the insect has been broken down by the bacteria, and only hair, bones, body spurs and skin sacs remain."

"This insect is called a gnat, and it lives in the habitat of aquatic organisms, including bathtubs, wash basins, etc., and most commonly in sewers."

"The problem is that if insects are going to become dried corpses, then the surrounding environment should be drier. How can a place where a gnat lives, such as a sewer, be dry?"

Ma Hongwen finally couldn't figure out his head like the second monk, and a pair of small eyes blinked and blinked: "That is to say, even if Wang Yuan's goose is long

Time has hidden this finger bone in something like a sewer, and there shouldn't be a dried corpse of a gnat on the ring?"

The medical examiner nodded, and then finally uttered one of his guesses: "Unless...... The place where the finger bones were hidden, there used to be a large number of gnats, but they quickly became dry and never damp since."

After Ma Hongwen came out of the forensic office, he only felt that his head was big.

Wang Yuange was not born to Wang Wenhui and his wife, what the hell is going on? Is there any connection to his death? Who are his biological parents?

Originally, he simply wanted to confirm whether Wang Yuan'e committed suicide or killed him, but it turned out that Wang Yuan'e's "parents" were very likely to die of murder.

Who will kill Wang Wenhui and his wife? Wang Wenhui is a hero of the Vietnam War, although he is short-tempered, he is not an unreasonable person, let alone a local "village bully" and "bully", he has a good reputation among the neighbors, and people who have sought him for medical treatment are also full of praise for his medical skills.

Zhang Xiuwen is suspicious, but the finger bone is here with Wang Yuange......

It's really fucking messy, and it's messy with cuts.

Ma Hongwen, who was the first and two big, lowered his head and walked in the direction of the interrogation room, but as he walked, he suddenly stopped, tore his throat and shouted at the staff who were hurrying around, "Where is Duan Ming? Tell Duan Ming to come and see me."

Ma Hongwen gave Duan Ming a relatively simple task: he wanted to know the "fire" accident that killed Wang Wenhui and his wife in 2001, and what day it happened; When Wang Qianshan ran away from home, and what day was it.
