On a cold w intermorning,the road was covered w ith 30cm-thick snow.在一個嚴寒的早晨，路上的積雪厚達30厘米.

Tom killed a person in his home,walked through a vacant lot and carried the body to an em pty room under construction.湯姆在自己家中殺人后，穿過一片空地，將尸體扛到附近一所正在建造中的空房內(nèi)。

Then Tom walked the same way back and called the police,reporting that he found someone was killed by accident.然后湯姆原路返回家中，撥通了報警電話，裝著若無其事的樣子說發(fā)現(xiàn)有人被害了。

The detective arrived soon.He checked the footprints in the snow and cried:“You are lying.You are the murderer!”偵探趕到后，查看了那個人往返現(xiàn)場時留在雪地上的腳印，便厲聲呵斥說：“你在說謊，兇手就是你！”

How did the detective know the fact?你知道偵探是怎么判斷的嗎？
