So where was the GFI on this blown fuse?  Aren't electricians presumably wired for safety?  I suppose that cowards span the spectrum from nice to terroristic kinds of guys.  It takes a beastly kind of coward to drown an innocent, intelligent creature.  (Psych 101)  If that is what really had occurred to a pet, then cowardice is this guy's true nature.  Acting out death violently upon animals is not uncommonly seen in  prescient serial killers.
