Not sure which thread I should put this in but I'll put it here.

Hersh Wolch, who was a "passionate, tenacious" defender of the wrongly convicted, has died of a heart attack at age 77
He was most famous for clearing David Milgaard of the wrongly convicted murder which I will link at the bottom of the post. He helped convict the real killer, Larry Fisher. He was also involved in numerous other cases such as Steven Truscott.

Also, I'd just like to note that David Milgaard is the subject of one of Tragically Hips' most famous songs, Wheat Kings. David Milgaard is a very interesting story for sure.
