第六十二章(5/13)

                                                                                                         看来，这两次的作案者是很相似的。
                                                                                                                                                                “此外，你还注意到别的没有？”十津川继续问。
                                                                                                                                                                “我到家之后，发现上衣前胸有血迹，也许是那个人撞我时沾上的。”
                                                                                                                                                                “那件上衣在哪呢？”
                                                                                                                                                                “准备明天送洗衣店去。”
                                                                                                                                                                “送洗前，让我们查一下好吗？”
                                                                                                                                                                取得长谷川同意后，他的西装上衣立即被送到“科研”调查血型。
                                                                                                                                                                调查结果，果然是B型血。
                                                                                                                                                                但是，除此之外，凶手一直无影无踪。
                                                                                                                                                                调查过京王线最后一班电车的站员，各站均未发现身穿白衣白鞋的青年人。
                                                                                                                                                                看来凶手可能步行逃逸，也可能事先将车子藏在附近，作案后驾车跑了。
