First things first, I factored in journey to crime distance.

首先我加入了犯罪现场距离
If you look here,

如果你观察这里
You'll see that this area of Portland

就会发现波特兰这一区域
is well within the expected 5-mile radius.

完全在预期的五英里地带之内
I also factored in distance of decay.

我还加入了衰减距离这一因素
What does distance have to do with decay?

衰减距离有什么作用
It's how geo-profilers measure relative probability

通过这种地理侧写可以测算
of an offender traveling outside his comfort zone.

罪犯离开其安全区作案的可能性
Unsubs prefer to stay in an area that they know well.

凶手一般都会选择他们熟悉的区域
Like you'd commute to work or to the gym.

就像你去上班或去健身房一样
The closer the crime scenes, the greater likelihood it is

犯罪现场越近那就越可能靠近
That the unsub lives or works nearby.

不明嫌犯工作和生活的区域
