On the afternoon of September 9, 1996, Junko Kobayashi, a 21-year-old student at Sophia University, was bound with tape and fatally stabbed inside her residence in Katsushika Ward. The residence was then set ablaze.

Police had previously revealed that a DNA analysis of material left behind on a match box and futon concluded that the suspect is a male with blood type A.

On Monday, members of Kobayashi’s family handed out leaflets with information on the case to commuters at two railway stations, including Shibamata Station on the Keisei Kanamachi Line.

“My daughter’s life was taken just before she was set to study abroad,” said Kenji Kobayashi, the 72-year-old father of the victim. “I can never forgive the criminal, who has taken away the dreams and hopes of a young person.”

Last year, police issued a 3D video that recreates the area outside the crime scene in a separate attempt to solicit the assistance of the public. In the 90-second clip, a man wearing a yellow raincoat stands in front of the residence as rain pours down around the time of the incident.

The existence of the man at the crime scene was a new development based on an eyewitness report, police said last year.

Thus far, police have received more than 1,100 tips in the case, but none of them has resulted in an arrest.

A reward of up to 8 million yen is being offered for information that leads to the resolution of the case. Persons with such information are advised to call the Kameari Police Station at 03-3607-9051.
