Relatives of an Asahi Shimbun reporter who was murdered on May 3, 1987, have expressed frustration that the case, on which the statute of limitations expires next month, remains unsolved.

Yuko Kojiri, 42, the wife of 29-year-old Tomohiro, who was based at the daily's Hanshin Bureau in Hyogo Prefecture, said in a statement released Friday by the Asahi Shimbun that she still has a great deal of unresolved anger over her husband's death, made worse because his killer remains at large.

"I feel pain and am at a loss for words just thinking about the criminal. I want to know the truth behind why my husband was killed," she said, adding that there is no statue of limitations on the anguish for her and her family.

Their daughter, Miki, who is now 17, was quoted in the statement as saying she wished she had been able to talk with her father about the books he liked, or seen him blush when she gave him presents on special occasions. Miki was 2 when her father was murdered.
