The septuagenarian lady was stabbed in the chest and died mysteriously in the living room, the wife fell on the bathtub wearing a shower curtain, the ground was full of glass shards, and the furniture on the wall was stained with blood.

And that's not all, what's even more bizarre is that the operator clearly remembers that he received the old woman's call to the police, but there was no blood stains on the phone in the living room and no fingerprints of the old woman.

Officers carefully examined the two bodies, and although the old woman had smashed the glass table, the real cause of death was the knife in her chest.

There were blood stains on the wall of the bathroom, which also corresponded to the wound on the back of the old man's head.

Combined with the cracked windows, the officers made a rough guess.

This is the first floor, the murderer broke through the window, first subdued the old woman, then used the knife in her hand to kill the other party, and then threw it on the glass table, and was about to leave when he heard the sound of the bathroom.

He realized that there was another person in the house, so he hugged the old man through the shower curtain and fell down the wall, and the old man fell to the ground with his nose hitting the faucet.

But there were no clues left by the murderer at the scene to support the policeman's statement, and the most important thing is that they did not find a motive for the crime.

The family's money and cards are all there, and the parrots worth tens of thousands of yuan are also intact, indicating that the murderer is not for money.

Sister Xi found a family photo, in addition to the couple, there were parrots and a cat, but only parrots were found at the scene, maybe the cat was scared away by the murderer.

They learned through the landlord that the window of the room had been broken for several weeks, and that the old man had broken it himself.

He also revealed that the old couple had a deep conflict with the next-door neighbor, and the neighbor even called to intimidate the couple.

The neighbor explained unhurriedly that he hated the couple very much, because the parrot they raised was so noisy that it kept screaming all day long, and he had long seen that the parrot was not pleasing to the eye, but it was not enough to kill the couple because of it.

Besides, the two of them usually quarrel endlessly, and sometimes they will fight, and they don't have to do it themselves at all, and at the time of the crime, he was connecting with the female anchor, and there was a full alibi.

The police wanted the contact information of the female anchor to collect evidence, and Sister Xi investigated the phone records of the couple's house and found that the old lady would call the police almost once a month.

called the police to deal with the family dispute, it seems that the neighbors are telling the truth, and the couple is indeed at odds.

The police also found that all the blood stains in the living room belonged to the old lady, and no fingerprints other than the couple were detected in the house.

Sister Xi guessed that maybe there was no murderer at home, the real murderer was the old man, he couldn't stand the quarrels day after day, and directly stabbed the old lady to death with a knife, and then went to the shower to take a bath because of the bloodstains, and as a result, a foot slipped and fell to death in the bathtub.

If this is the case, then the knife on the old lady's body must have the old man's fingerprints, and there must be the old lady's blood stains in the bathtub.

The forensic examination found that the old lady had only one stab wound all over her body, and the police came to the scene and the knife was inserted into the old lady's body, which could not explain the blood stains all over the house.

And Sister Xi checked that there were only the old lady's fingerprints on the murder weapon, and there were only the old man's blood stains in the bathtub, all of which did not match her speculation.

The medical examiner explained that although the old lady had only one wound on her body, she had many scratches on her head. These were all hooked by the claws, and he thought that the parrot had killed the old lady.

Trained parrots are very intelligent, and they can master many skills that only humans do.

The police returned to the crime scene again, they found that someone had been here, the crime scene was destroyed, and fortunately the parrot was still at home.

The police found a little feather in the drain of the bathtub, indicating that the old man was bathing with the parrot, and Sister Xi found cat paw prints on the carpet, it seems that the cat came back and stepped on some things at the scene, and now it is hiding under the bed.

The two pets were brought back to the lab as a suspect bird and a suspect cat, and as soon as they met, they quarreled about what was going on with the family.

Even if there is a conflict between the owners, there is a-for-tat relationship between pets. According to the speculation before the speech, the two pets were directly related to the case, and they had to be fingerprinted.

They found the old lady's DNA on the parrot's paws, blood on the inside of the wings, and shower curtains on the cat's paws.

Sister Xi made the final guess that the old lady was attacked by a parrot, and the DNA on the parrot's claws corresponded to the old lady's head cuts, and the old lady's blood stains stood on the parrot's wings, so when it flapped its wings, it scattered blood stains everywhere.

The old man's death was the responsibility of the cat, who was bathing with the parrot, and the cat, which has the nature of hunting birds, aimed at time and pounced on the shower curtain, causing the old man to slip and hit his head against the wall.

The frightened parrot pounced on the old lady and scratched her head with its claws, until the old lady slammed into the glass table and was stabbed to death with the knife she was holding.

After a tie with the cat, the parrot flies back to its cage and locks itself up.

But there is one more thing that is not explained, who called the police, they are puzzled by this problem, and they are careless The fruit knife scratched their fingers, watching the wound bleed, the parrot skillfully walked to the front of the phone, pushed away the microphone and pressed 110, and shouted "Help me, save me"

At this point, the truth of the case has been revealed....
