Milwaukee arena reporter Don Walker has passed away

I’ve poked a lot of fun at the Milwaukee Journal Sentinel’s Don Walker in recent months — most memorably for this — but he’s done a bunch of good reporting as well, all part of his assignment to cover the Bucks arena deal on a daily basis. And even if he hadn’t, it still would have been a shock to see this just now:

No word yet on the cause, though Walker was still tweeting as recently as last night, so presumably something sudden. (From his college graduate date, it looks as if Walker was in his early 60s.) Our condolences to his family and friends, and respect to someone who clearly cared a lot about reporting on the sports-business world, even if we came at it from very different places.
