Ok I think I figured it out. Somewhere in the mission is a note saying that the (or a) key to the legal district is in the top floor of the building with the balcony which the guards are using as a look out. Going there you'll find instead of the key the hat of the hatters gang. They left it as a signature after stealing the key. Chauncy (the hatter who stole the key) was obviously hurt during his escape and died eventually. There's another note saying something about this heist.

In 2 playthroughs I found him the first time in the big abandoned building with balcony next to the exit of apartment #10 and in the second playthrough he was on the top floor of the hatter's building.

I think it depends on the chaos level reached in the mission before where you'll find him....
