After reading some more of this thread, I started up my fortress, with about 60 dwarves in it. My dwarves had individual 2x2 bedrooms, with doors. I told the miners to dig out those walls, and I ordered the doors deconstructed, to make them sleep in sight of each other. This would increase unhappy thoughts due to noise while sleeping, but so be it.
Before I could even make progress on that, one of my farmers was murdered in his bedroom, and the body discovered, drained of blood.
I was able to finish the mining and deconstructing before the next murder. The next victim was killed in front of a whole room full of witnesses. Subtlety is apparently not this particular dwarfpire's strong suit. I went to the justice screen, with all the unanimous eye witness reports accusing the same dwarf, and convicted her of the murder.
My newly appointed sheriff didn't even have a uniform yet. And I didn't have any cells built yet (in progress!). And I didn't have a hammerer yet. So the sheriff's sentence was "Beating". She went after the vamp with her fists, leaving her with a broken thumb, several teeth knocked out, and assorted bruises.
The bloodsucker went to the hospital to Rest. The chief med diagnosed her, and prescribed cleaning, setting the broken thumb, a surgery, some suturing, etc. and proceeded to fix up the murderer.

I decided to convict my known vamp for the first murder as well (despite the fact that a whole bunch of immigrants had just arrived, two of them with "Great" skills, and who-knows-how-many other vampires might also be in the fort).
So I went to the Justice screen again, and convicted her of the first murder. She was still lying on the table in the hospital room. My cells had been constructed now (just a rope and a bed), so the sheriff sentenced the vamp to 201 days in prison. The sheriff went to the hospital with a Chain Animal job, grabbed the vamp from the table, and started taking her to the jail.
Meanwhile, the doctor was en route to the table for something or other. When the doctor got to the table, the game crashed completely (core dump). I'll file a
bug report.
