If it 20 to 25 latinos it might be a situation where they are illegals working for a company that has brought them up from south of the border.
There was a fast food company in Phoenix that was importing illegals to work in thier company and they had large amount of people living in one house and the company had four or five of these houses around the valley.
I want to say the company was Roberto’s…
Anyway these houses are common place in the PHX area and get raid by ICE all the time.
You might have something similiarly going on or a mule house…
