After reading all the files and transcripts, Lin Feng also had a general understanding of this case.

The four deceased, each from a family of four.

Two of the old deceased, about sixty years old, were husband and wife, while the younger deceased was their daughter, and the youngest deceased was their daughter's son.

"I didn't expect the murderer to even let go of the child, it's so cruel, I will definitely find out the murderer." Lin Feng looked at the record, as well as the file, it was really too cruel.

"Brother Feng, the old policeman said in the past that the most suspicious was the son-in-law of the two old deceased, but after we caught him, we released him again, because we couldn't find any evidence left by him at the scene, and the murder weapon did not have his fingerprints." Wu Liang had a headache, knowing that the other party was a suspect, but he didn't find evidence.

"Other than that, there's no other evidence?" Lin Feng felt a little headache, there was no evidence at all, and it was really troublesome to solve the case.

And that suspect, it's impossible to kill all four of his family, unless there is some big contradiction.

Lin Feng was almost certain that the murderer was someone else, not the son-in-law of the deceased.

The son-in-law of the deceased was named Zhao Bingtao, and the four people who died, one was his wife, one was his son, and the other two were his father-in-law and mother-in-law.

Even if there is a reason for his father-in-law and mother-in-law, he can't kill his wife and son, right?

"No, by the way, only the bloodstained clothes, which were worn by the deceased, are still kept, but we have tested the DNA, and we have found no DNA left at the scene except for the blood of the four deceased." Wu Liang explained.

"Take me to see those bloody clothes." Lin Feng said suddenly, now just speculation, I can't guess anything, Lin Feng is not a detective.

"Okay, Bloodcoat is in the archives." After Wu Liang finished speaking, he and Lin Feng walked out of the room and led the way in front.

Lin Feng followed him, constantly walking into the passage, there were many rooms here, all of which were for putting evidence or other useful things for handling cases.

After walking to the last room, Wu Liang stopped, took out the key and opened the room.

A musty smell came over from inside, apparently the room hadn't been opened in a long time.

If it was someone else, Wu Liang might not open it, after all, this is the secret of his work.

However, Lin Feng is no one else, he is the person of the wolf fang, and the wolf tooth has the right to find any evidence.

There are a lot of things stored in it, all of which are old things, or some evidence of cases that cannot be solved for the time being.

Wu Liang took a box next to him, opened it, put on gloves, and took out the bloody clothes.

Although fifteen years had passed, looking at the large patches of blood on the bloody clothes, Lin Feng could imagine how tragic this case was when it happened.

"Brother Feng, can you see anything?" Wu Liang looked at Lin Feng and looked at the clothes with a serious face, not knowing what was going on in his mind.

"I can't see anything with these bloody clothes alone, so take me to the scene to have a look." Lin Feng said.

"Uh......" Wu Liang was a little embarrassed, fifteen years have passed, and the scene has long been ever-changing, and now I don't know if it exists.

"What's wrong?" Lin Feng looked at Wu Liang with a look of embarrassment.

"It's nothing, I'm just thinking, I don't know if there exists or not, after all, fifteen years have passed." Wu Liang grimaced bitterly.

"Just take a look, lead the way."

Lin Feng walked outside, and after Wu Liang cleaned up, he chased after him at trot, and the two walked outside the door of the police station.

"Brother Feng, in order to avoid attracting attention, we are secretly investigating, so let's go cheaply." When Wu Liang came out just now, he had already taken off his police uniform.

"Okay." Lin Feng nodded, that's exactly what he meant.

Wu Liang got into Lin Feng's car, and under his guidance, Lin Feng drove to the scene of the crime.

"A family of four was killed, when the crime occurred, the murderer would definitely make a move, we went to visit and see if we could investigate anything, especially the child, who would definitely cry and make trouble when the crime occurred, and the people who lived nearby, if they could hear the movement, they could investigate it." Lin Feng said as he drove.

"Brother Feng, I've thought about this too, but fifteen years have passed, and the people in the neighborhood have probably moved away." Wu Liang said worriedly.

"Not necessarily, just take a look." Lin Feng said.

The car kept driving, and due to the investigation of this case, Lin Feng and Wu Liang's expressions became much more serious than usual.

After more than half an hour, Lin Feng finally arrived at the Blue Sky Community, where the scene was located.

The Blue Sky Community is a very old community, and most of the houses in it are old.

After getting out of the car, Lin Feng and Wu Liang walked in, in addition to these old houses, some have been demolished and rebuilt.

Unfortunately, the entire building where the crime scene was located was demolished and replaced with a new building.

But this building is empty, and there is no one to live in.

I guess you know that there was a murder here, which affected the sale of the house.

"Brother Feng, I don't think I can find anything here." Wu Liang also came to the scene of the crime for the first time, and he had a little headache.

The original scene no longer exists.

"Although the scene of the crime has changed, there are still people living in the old house next to it, have you seen it?" Lin Feng looked at the vicinity of this new building, there were many houses, they should know something.

There is also the old area, where most of the houses are used for rent, and there is a mixture of fish and dragons.

"I'll ask later, let's go up to the new building first." Wu Liang walked in front and walked with Lin Feng to the ten-story building.

"What did you say the scene was like here?" Lin Feng asked as he walked.

"According to the old policeman, the new buildings here are built the same as the houses at the scene, with more than a dozen floors and the same structure, the only difference is the old and the new."

"What is the floor on which the crime occurred?" Lin Feng walked up the stairs, although there was an elevator, but for the sake of the realism at the time of the crime, he still chose to take the stairs.

"The sixth floor."

Wu Liang and Lin Feng walked in the empty corridor, and the sound of footsteps kept ringing, crisp in their ears.

A few minutes later, Lin Feng and Wu Liang climbed to the sixth floor.

Lin Feng stood on the balcony of the sixth floor, condescending, and he could see clearly who was below.

"You said that before the crime, the victim would have just seen the murderer come in from below, but they didn't expect him to be the murderer." Lin Feng said suddenly.

"It's possible." Wu Liang's eyes suddenly lit up after Lin Feng's reminder.
