Mike Vanderbeck discovered the bag in a closet Monday while showing Amy Giordano's Hightstown apartment to a reporter for The Times of Trenton. He immediately called police.
The contents included $4.31, Social Security cards for Giordano and her 11-month-old son and her apartment keys. Vanderbeck was especially concerned because she also left an almost-full pack of cigarettes.
"She was a chain smoker," he said.
A nurse found Michael DiGirolamo outside Christiana Hospital in Delaware 10 days ago. The little boy had a note tucked into his diapers.
Neither Giordano nor the boy's presumed father, Roy DiGirolamo, have been seen for days. DiGirolamo, who is married, last reported to work about a week ago, while the last person known to have heard from Giordano was a friend who talked to her on the telephone four days before she abandoned her son.
