Lily was dead in her bathroom,and her body was discovered by a visiting journalist.He dialed the number 110.The detective and forensic arrived as quickly as possible.莉莉死在浴室里，尸体是被来访的记者朋友发现的。他立刻拨打了110，刑警和法医以最快的速度赶到了现场。

One hourpassed.The detective asked：“Have you found out the cause and time of the death?”大约过了1个小时。侦探问道：“死因和死亡时间出来了吗？”

“She was killed by someone 24 hours ago,but there is no trace of crime here.”answered the forensic.法医回答：“是他杀，大概已死亡24个小时了，但现场没有作案的痕迹。”

The detective said,“That sounds strange!”侦探说道：“那就奇怪了。”

The detective noticed the burning candle on the table.He turned on the light,only to find power was off.刑警忽然注意到桌子上的蜡烛在燃烧着，他顺手打开日光灯，却发现停电了。

All of a sudden,he realized and said：“The body was moved from some other place.”猛然，他意识到了什么：“原来这尸体是从别处移过来的。”

How did the detective offer such reasoning?请问，刑警是凭什么做出推理的？
