第三节(3/3)

                                 “我看不是这样的！”
                                                                                                                                                                “那你说是什么原因呢？”
                                                                                                                                                                “凶犯是强奸被害人，才把她剥得精光。如果目的只在抢劫，完全可以不扒衣服嘛！目的是强奸，而且把手表、项链都取下来，要让她身上没有任何东西。你想想，这里是杂木林，周围有人家，凶手理应尽快强奸完毕，可他竟连由美子的乳罩也扒下来了，这难道不说明问题吗？”
                                                                                                                                                                “照你这么说，凶手可能欣赏年轻女郎的裸体，因为昨天是月夜，很明亮。由美子的身体富于曲线美，凶手才将她扒光的？”
                                                                                                                                                                “可是，为什么连手表项链都拿掉呢？”
                                                                                                                                                                “所以嘛，我看凶手还是想抢劫才剥下来，但又觉得手表和项链容易查出，才又扔掉的。凶手还真不简单呢！”
                                                                                                                                                                真如田岛所以为的那样吗？手表是女用的，有时很难卖掉是事实，项链却不同，最近男人也常戴金项链，而且黄金价格猛涨，兑换现金也是容易的。还有，由美子的项链，只是普通的项链，没有特殊的特征。
                                                                                                                                                                既然如此，凶手为什么把到手的金项链扔掉呢？
