Solving Serial Murders:
Committed with a fish knife, then look to CG.
If it's a total Texas chainsaw thingie then look to Chaser.
Bludgeoned to death with a baby pineapple and subsequently gnawed on postmortem by a corgi, then look to Pants. Also if no bodies found, cause feed to sharks.
Clawed to death by a pride of slightly domesticated cats, then look to KC. Think S. King's Sleepwalkers.
Porsche tire tracks all up and down their backs, probably Boxster.
Strangled with an ascot and a boat shoe shoved down their throats for good measure, gotta be BU.
Sonically discombobulated by high frequency bagpipe tones, Woo.
Choked to death on chicken wing bones with a hefty extra dose of sauce, look to 55. She may also have inadvertently left a clue by losing one of her pair of big glasses.
