Cheryl, Bletcher and others in “The Judge”

Wherein where previous findings indicate the other body parts were all sundered while the victims where alive, but I believe this tongue was removed after death. Also the instrument wasn't as sharp or as skillfully used as in previous excisions.

Would that point to, uh, rage, loss of control?

Doubtful. The cuts aren't unusually forceful, just imprecise. A few false starts, repetitive blade strokes.

Frank?

We do have a pattern change.

Unlikely to be intentional deviation from the established method.

So how do we account for it?

The victim died prematurely or the killer was interrupted.

The perpetrator may be getting lazy, becoming more casual as his activities lose their novelty.

So it really doesn't tell us much then.

Well, it tells us that he's less concerned about being discovered but no less dangerous... possibly more so. There's nothing here to indicate that this is going to stop.
