   • 1987 March 10, “Nerima no shufu koroshi, hannin wa otto no kameraman [Nerima ward housewife murdered, cameraman-husband suspected]”, in Mainichi Shimbun, page 23:

     現(げん)場(ば)の状(じょう)況(きょう)も不(ふ)自(し)然(ぜん)で、紀(のり)子(こ)さんのサイフから生(せい)活(かつ)費(ひ)の現(げん)金(きん)二(に)、三(さん)万(まん)円(えん)が抜(ぬ)き取(と)られていたがわざとらしく、紀(のり)子(こ)さんが保(ほ)存(ぞん)していた買(か)い物(もの)のレシートや領(りょう)収(しゅう)書(しょ)が台(だい)所(どころ)に散(さん)乱(らん)させられ、タンスの引(ひ)き出(だ)しが物(ぶっ)色(しょく)されたように開(あ)けてあった。

     Genba no jōkyō mo fushizen de, Noriko-san no saifu kara seikatsuhi no genkin ni, sanman en ga nukitorarete-ita ga wazato-rashiku, Noriko-san ga hozon shite-ita kaimono no reshīto ya ryōshūsho ga daidokoro ni sanran saserare, tansu no hikidashi ga busshoku sareta yō ni akete-atta.

     Conditions at the crime scene were also unusual: 20 or 30 thousand yen had been taken from the living expenses in Noriko’s wallet, seemingly deliberately; shopping receipts and hand-written receipts that Noriko had been saving were scattered around the kitchen; and a drawer in the wardrobe had been opened and ransacked.
