The police said that the killer, who is in custody now, is a very shy person and cannot start a conversation with an unfamiliar woman. However the anonymity of the dating services gave him a chance. One of the women he met was killed after several dates, and the second was killed right after the first date. The bodies were thrown into a river, the police say. Experts say that in Japan the amount of similar murders threateningly rises. At the same time in Europe and America where in general the amount of crimes is much higher, there are not many murders.
The psychological reasons of this phenomenon, experts say, are that Americans and Europeans are more liberated and open. Japanese are shyer and more closed to relationships with women. Therefore they use dating services where they can keep anonymity often. However shy maniacs may also take the advantage of these anonymous dating services.
Therefore Japanese police and mass media warn: despite the message content, people who got acquainted through dating services should be careful at personal meetings.
