How did you find him? I've beaten over six gang members. The journal says to talk to the detective, but he's not at the light and I can't click on the police station so he seems to be a no go. I've tried hanging out at the bar again, but nothing.
After poking around, I think it's glitched and just broken. The TV says I already beat the boss. I never talked to the chief after beatin the six gangs and I never beat the boss. I'm also not replaying everything. If this actually releases on steam (it's been "almost ready for release for like 3 years now", I hope it is significantly less buggy.
