-
Chisels to the brain.
-
And a lot of creepy-crawlers.
-
Forensics?
-
Neither crime scene yielded much results
-
because of too many bugs and critters.
-
The choice and placement of the chisel is very specific.
-
Maybe the unsub symbolically is destroying
-
the thoughts and memories of the victims.
-
It looks like they were facedown when the chisel went in.
-
Remorse?
-
Could be the killer knew the victims,
-
didn't want to see their faces when he was killing them.
