Two people seen on security video near where a 13-year-old boy was found dead on a river bank in Kawasaki are about the same age as the victim, NHK said Monday, citing police analysis of the images.
The unclothed body of Ryota Uemura was found Friday morning on a bank of the Tama River. He apparently bled to death after being slashed with a sharp object or objects.
The area is mixed industrial and residential. Uemura's body was found a few hundred meters from Minatocho Station on the Keikyu Daishi Line, and about 2 km from the residential area where he lived.
