Who's Crack House is it?

When I read things in the news like "He said he knew the men from a "crack house" in the 500 block of West Wilson Street, which abuts the backyard of Zimmermann's apartment." I just have to ask "OK - so who's the landlord who has a crack house?". If the line from this article yesterday is correct, here's the possibilities from the assessors office. I left off the ones that appeared to be owner occupied, because while I suppose it's possible, I decided it was highly unlikely and they shouldn't be included:

Of course, that wasn't my first thought when I read that awesome piece of reporting from Jason Shepard about the 911 call and Brittany Zimmerman. I think I was stunned for at least a half hour, then sick, then angry, then determined to do something about it, then angry again, then sad for her family, still feeling sick, then angry enough to want someone's head on a platter. Rumor has it, Progressive Dane County Board Supervisors will be asking for an audit of the 911 center. While that might make sure it won't happen again, it seems so inadequate for the anger that I feel.
