Jack the Ripper has always been a mystery in London**, and his bold and cruel methods of crime have become a nightmare for the British, because the criminal investigation methods are too backward, and the real murderer has not been found, but in 2007, at an auction, the cloak left by the Ripper appeared. 
After DNA identification, Aaron Kosmiski, who immigrated to Poland, may be the ripper, Aaron and the victim lived in the slums of the East End of London at the time, and the relationship is deep, that is to say, the ripper, or an acquaintance who committed the crime, speaking of the acquaintance who did not find the ** to commit the crime, 23 years ago, NTU 119 The case of corpse mutilation has not been solved so far. On January 19, 1996, a cleaner near Nanda was cleaning, it was winter, there were fewer pedestrians on the road, she swept the snow aside, and when taking out the garbage, the cleaner found a black bag in the garbage bin, the bag was not old, she opened it and found that it was some slices of meat, half-cooked. 
Take a closer look, there are three fingers in the bag, which can startle her, the cleaner immediately chose to call the police, in the next few days, ** search around the south of the country, and successively found the rest of the corpses in Longwang Mountain, Huaqiao Road and Shuizuogang, a total of more than 2,000 pieces of meat, which is really appalling. In the identification, it was finally confirmed that the victim was Diao Aiqing, a freshman girl at Nanjing University, Diao Aiqing was born in 1976, a native of Diao She Village, Jiangyan City, Jiangsu Province, when the body was found, Diao Aiqing had been missing for nine days, and in early January, Nanjing University had not yet had a winter vacation, and the case-handling personnel also went to Nanjing University to conduct relevant investigations. 
Diao Aiqing skipped class on the 9th, and did not go to class for a day, according to the roommate, Diao Aiqing went out to play with a friend, because Diao Aiqing came back on the night of the 9th, and Diao Aiqing did not go to class on the 10th, and Diao Aiqing disappeared from the afternoon of the 10th. At that time, Nan University students were preparing for the unified examination, everyone was busy studying, Diao Aiqing didn't go to class for two days, obviously strange, who was the friend she was with could let her not go to class for two days, if it was a couple, then the biggest possibility was Nan University student, Diao Aiqing was not tall, ordinary looking, she was the kind of girl who was relatively quiet, and her roommate also said that she couldn't have a boyfriend. 
In addition to the boyfriend, the most likely is that an acquaintance committed the crime, according to the situation of the corpse, ** has excellent psychological quality, and has a certain experience in handling the corpse, but if an acquaintance commits the crime, there is no need to make a storm in the city, around the discarding of the corpse of Nanda, the goal is too obvious. Judging from the "half-baked" and some "ripe" situations of the corpse, **when disposing of the corpse, there was a panic, it may be** a person with a family, and** very unfamiliar with the surrounding area, he neither buried the corpse nor threw it into the river, but found a few garbage cans at random. 
The area around Shuizuogang is relatively hidden, and the torso was found here, which may be that the smell of blood is too heavy to deal with, and it can be inferred that ** has a certain economic ability to buy transportation, otherwise it is difficult for him to carry his bag to Shuizuogang, and it is even more impossible to take the bus. 
Although the case-handling staff also locked up the doctors, cooks, and butchers near Nanda after a difficult investigation, there is still no progress, and now 23 years have passed, **whereabouts are unknown, and with the "**case"** arrested, I also hope that this cruel ** can be arrested as soon as possible. A 20-year-old schoolgirl was killed, the whereabouts of her body are a mystery, and the cleaner She was in the garbage can, with more than 2,000 pieces
