CBS Sacramento: Calif. Homeless Found Living in Furnished Caves 20 Feet Below Street Level

EXCERPT:

APODACA: "I've covered a lot of homeless stories in the past, but I've never seen such elaborate infrastructure for encampments. It starts with these makeshift steps that lead about 20 feet down below to where these caves are hidden. You can't even see them from up above, and that's likely why they went undetected for so long."
