On Tuesday, investigators found a head belonging to a man and a torso in some soil of the riverbed of the Ina River beneath a bridge.
The day before, investigators working off a tip found two arms and two legs, all of which had experienced a small degree of decay, in some bushes. The arms had been cut at the elbow. The legs, whose feet were wearing black socks, had been severed at the knee.
The bushes where the limbs were found are about 10 meters away from the soil where the torso and head were discovered.
The body is believed to be that of a male aged between his 20s and 50s. The person likely died several days ago.
On Wednesday, the head and torso will undergo an autopsy to determine the cause of death. The case is being treated as abandonment of a corpse.
