His first thought was that the killer had taken it.
Perhaps she had some sort of hard evidence and the killer took it.
In a very real way, he realized, the killer had taken two lives that night.
Why should the killer take the gun in the first place?
It looks as if the killer took his time with her.
The killer has already taken his victim, and he isn't going to take another for a while.
And she thought: I know why the killer took the feet.
The killer takes most of the crime scene with him.
"Either she did it and walked away or the killer took her with him."
I wondered if the killers had taken anything with them.
