第四百七十九章(4/6)

                                                                                                         如果那不是玩笑，而是凶手得意洋洋的预告呢？
                                                                                                                                                                可惜，赵涛毕竟不是侦探。
                                                                                                                                                                很快，三天过去，他却什么线索都没有得到，只是知道了张星语暂时被母亲以死相逼带回家，杨楠和父母决裂，已经买好火车票准备回来的消息。
                                                                                                                                                                他把学生处值过班的干事挨个问了一遍，却没一个人有印象谁来专门查过这三个学生家长的联系方式。他的收获，还不如杨楠打电话时候告诉他的东西更多。

                                                                                                                                                                “……就是咱们学校的女孩子，应该是连打了三个长途，就晚饭前刚下课那会儿。”赵涛匆忙描述了一堆，
