NBC Philadelphia: "A man with a U.S. census badge knocked on Amy Schmalbach’s door on May 4. Thinking that answering the door to a government worker was a safe bet, she did. And then she wondered why he looked so familiar.
As soon as the man left her Pennsauken home, Schmalbach realized where she had seen him before: on the state’s sex-offender registry."
