One day in 2002, two very strange car accidents happened in Finland. These two car accidents have attracted everyone's attention because the protagonists of the car accidents are two elderly people in their seventies. They are twins. It is reported that the twin brothers were killed by a truck because they were riding on the road, but unexpectedly, two hours later, his twin brother was also killed in a car accident on the same road. The most surprising thing is that when the twin brother was in a car accident, the police had not had time to tell him about his brother's death.
Second, there have been many twin crimes in the world. A similar jewel theft occurred in Germany in 2009. Later, after police investigation, it was found that the DNA of the suspect who stole jewelry was very consistent with a pair of local twins. But because the twins' genes are so similar, the police can't determine who stole the jewelry at all, and finally they didn't convict the two brothers. In fact, there have been many cases in real life in which twins cover up their crimes.
Thirdly, similarly, there is a very dramatic scene in Twins. In 2004, a girl named Mary gave birth to a child, but the father of the child did not know who the child was. Mainly because Mary once had sex with a pair of twin brothers on the same day, and because the DNA similarity of the twins is as high as 99%, even doctors can't tell who is the biological father of the child.
