here's a heat map of the last known location of missing persons in Milwaukee overlaid with the location of the house: https://www.jsonline.com/story/news/crime/2020/04/07/sex-trafficking-milwaukee-where-happens-who-happens/2939359001/ https://twitter.com/unitaskersmke/status/1275637376782684161

sorry, residence, not location. it's a bit hard to see in the overlay but the house address is just a bit directly south of the highest density area

looking at that heat map I'd hazard there are three or four other trafficking sites, and no, they don't just line up with the areas of highest population

Fwiw I doubt this will be the end of it, there's interviews with the found girl's mother and one of the families that lived in the triplex house that burned. https://mobile.twitter.com/delmoi/status/1276878378201735168
