The search for 9/11 victims resumes. On Monday, more than 11 years after the attacks of September 11, 2001, New York City started sifting again through debris recovered from the World Trade Center to look for victim remains. It's the first such operation since 2010. Sally Regenhard still waits for remains of her son. She and some other victims' families lack confidence the search will be done right -- and want reasurrances from the city's chief medical examiner.
