This unsub strikes in the home rather than outside

虽然在外面更容易实施绑架
where he could more easily abduct his victims.

但不明嫌犯选择在家里袭击被害人
Now, this tells us that his social skills are most likely lacking

这表明他很可能缺乏社交技能
and he may not have the confidence to talk to women.

可能没有足够的自信与异性对话
His confidence with killing, however, is growing.

但他杀人作案的自信心在膨胀
He's gone from hesitant strikes in the victim's home

早先在被害人家中下手时尚有犹豫
to painting the walls with blood.

如今胆敢在墙上涂鸦
Our unsub is developing a taste for the kill.

他已经开始追求杀人艺术了
And his victims share similar features and backgrounds.

被害人的容貌和背景都比较相似
And we believe that they represent someone

我们认为嫌犯曾经受过委屈
whom the unsub thinks has wronged him

从而将被害人看做是替代品
and he's taking out his rage on them.

在她们身上发泄怒火
