A man shot three, commited a suicide

A sixty-year-old man who had a gun commited a suicide after he shot three men. It occured on Friday, in a building in Yokohama.
They were arguing about the loan payment. The man who killed himself was a member of a gang, which is something to do with Inagawa kai, a major yakuza group.
One of the three people got shot in the left chest, the others got shot on the neck.
The incident washapped near the busy subway stationon the afternoon.
Because of the incident it became clear that the group has a connection with owing a gun, which is illegal in Japan.
What was happed in the incdent can be ironical because the man couldn't kill any of the three at the moment, although he killed himself.
