Michael Powell was locked up at the age of 18 for murdering two men.

He served some 22 years in jail and then spent some time in a mental institution. For more than a decade, he has been living in a tent off of a highway in Camden.

"I try to live good," he says, wearing a black long sleeve shirt with no jacket in the 12-degree weather. He stands next to his tent, which holds a couple mattresses, some plastic drawers, a propane heater and a knife. "These people walk around here all dirty -- that's unnecessary. If you respect yourself, then you wash every day. Wet wipes -- baby wipes -- you wash with them."

Between his criminal record and little work experience, Powell has had a hard time finding a job. He has picked up some occasional work -- like doing carpentry for a friend -- but he hasn't had a stable income.
