True, they have been good of thinking up different murders. Looking up the murder weapons, we see there's been:

4 normal knife kills (Pocket knife, hunter's knife, paper knife, slashed throat)

3 stabs with special items (Candlestick, Pitchfork, Scissors)

5 special blade kills (Carved open, Disemboweled, Taxidermied, Injestion of blades, ritual carving)

3 poisoned foods (Food, Cupcake, Olly's Beer)

2 special poisons (Neurotoxin, Floral poison)

3 environmental kills (Window, drown, pushing)

2 crushing (Sandbag, Chandelier)

3 bludgeonings (Hammer, Glass bottle, Bat)

2 Fatal Injections (Experimental, EPO)

2 animal kills (Ants, Piranhas)

2 bombs (Bomb alert, Close proximity)

then 11 murders in their own classification (Sawed, Tenderized, Gunshot, Crucified, Roasted, strangled, arrow, concrete, iron maiden, Electrofied, Hung)

So even if they used the same murder method, they mixed it up with different ways of doing it. Just look at all the ways they used blades. Bravo Criminal Case team for keeping it fresh.
