Tokyo police will dispatch officers working on the December killing of a family of four in Tokyo to South Korea to interview the manufacturer of a pair of athletic shoes they believe were worn by the suspect, police said.
Police believe a size 28 cm shoe print found in the house in Setagaya Ward where the four family members -- a couple and their daughter and son -- were found dead may have been left by the killer.
The print matches that of a shoe made by a South Korean company under an exclusive manufacturing contract with British shoemaker Slazenger.
The officers from the Metropolitan Police Department will leave Japan later this week, police said.
Mikio Miyazawa, 44, his 41-year-old wife, Yasuko, and their two children, Niina, 8, and Rei, 6, were slain in their home between Dec. 30 and 31. The suspect is still at large.
