Well, after a rather pointless pumping project (pumping water from the brook, since I forgot you could 'dry pump' a pump operator to muscular superiority) left a field near my fortress covered in 1 deep water, I waited until winter, then, as planned instructed my Legender Miner/Legendary Bookkeeper/more awesome skills/maxed out stats (whom I had furnished with a room full of jewel-encrusted masterpiece furniture, and an artifact scepter) to mine the resulting ice walls. First thing that happens is this:
One dwarf-sized block of ice to the head later, Bomrek is a corpse. Confused and shocked, I scan the z-level above to see that some of the iceblocks are 2 z-levels high, and he'd apparently gone straight for mining one of the bottom ones out.
I was wondering, what causes these rather monolithic ice blocks to manifest? I certainly wasn't expecting my little puddles to crush poor Bomrek.
In tribute, I am constructing his tomb on the far side of the brook, in the remnants of two soon-to-be mined out and floored over Murky Pools. 'Parchtufts', his appropriated Bauxite scepter, shall accompany his bauxite coffin into the tomb. Oh, such a foreboding name! If only we had heeded its ominous warning!
Until his tomb is completed, his body shall rest in the dining room, for all to pay their respects.
Edit: Naturally, it took less than thirty seconds for Vucar the Engineer, an almost completely unskilled recent migrant, to claim Bomrek's old room and go to sleep in it. He shall be kicked out to make way for Lead Earthshaper Cilob, who will take over Bomrek's administrative duties.
