A 34-year-old single woman was killed in the dormitory, and the death certificate said abnormal death. This happened in June of Heilongjiang anniversary 18. According to the police, the single woman was strangled by the murderer. Just the day before the single woman was killed, I chatted with my colleagues and mentioned that there was a murder case in the community where she lives now, and she was killed the next day. According to the police investigation, the single woman who was killed had no contact with the murderer, and they didn't know each other, and the murderer had fallen to death during the escape, so it was impossible to file a case. The community where the murdered single woman lives is a public rental house provided by the company, so the management of this community is very imperfect. Without security guards and access cards, some dangerous people can enter at will, and there is no camera installed, so it is difficult to verify even if there is an accident. The single woman who was killed was killed at home, but because of the epidemic, she was sending a work summary to her colleagues when she was killed. Therefore, the single woman was killed at work, and her family members have applied to the relevant departments for compensation for work-related injuries. It's really unfortunate that this single woman was killed. The murderer was murdered on 16 and was pursued by the police. 18, fled to the murdered single women's community. It happened that this 34-year-old single woman was killed this time, which was really an accident. No one expected such a thing to happen, and after the woman was killed, the murderer continued to escape, and in the process of escape, he hurt others for the third time, but only caused minor injuries to others, and there was no danger to his life. It can be said that this single woman met a crime fanatic. Such a thing is purely accidental. The occurrence of this incident also gives us a feeling that sometimes we really don't know which comes first, the accident or tomorrow, so we must cherish every day we are alive now.
