According to the Kanagawa Perfectural Police the two Chinese sisters who were found murdered had died from strangulation.
The bodies of the two women were discovered in bags in the woods on the night of July 13 in the town of Hadano.
The two sisters, Chen Baolan and Chen Baozhen, both lived in Yokohama where their bodies were found.
The Chinese Foreign Ministry asked the Japanese Police to solve the case after the father of the two women had been unable to reach them since 7th July. So he reported the matter to the Chinese Foreign Ministry.
Many people who had been familiar with the sisters said that they suspected one of the customers, from the cafe where one of the sisters worked. The man had been seen going in and out of the apartment several times.
A 30 year old Japanese man has been arrested by the Japanese police. He is a married man and was having an affair with Chen Boalan. The case is being investigated by the police.
