It has been revealed that only ten of these sweat shirts were sold within Tokyo.
We have discovered the owner of one. We have been searching for others who may have purchased the other nine.
There were only the four stores at the time of the incident which exclusively sold casual clothes in Tokyo, including this type of sweat shirt:

(M/X and Marufuru are not doing business at present.)
If you have the same kind of this sweat shirt or know someone who does, please let us know.
You may be afraid of reporting this to the police, thinking that if you have this sweat shirt or remember having bought one, you may be treated as a criminal. There is no need to worry about such a thing.The perpetrator took off his sweat shirt and left it at the crime scene.Having the same sweat shirt now would, therefore, prove that you are not the perpetrator.Locating the whereabouts of nine other sweat shirts would directly lead us to identify the perpetrator.
We need your cooperation on this.
Two black handkerchief were left at the crime scene.
One handkerchief had a cut in the middle, which was about three centimeters in length. It is believed that the perpetrator let the knife run through this cut, so that he could use the handkerchief as a fallback.
The other handkerchief was folded like a triangle and looked like it was squeezed on edges. It is possible that the perpetrator used it as a mask.
