This photo released by the Kenya Presidency shows the collapsed upper car park of the Westgate Mall in Nairobi, Kenya Thursday, Sept. 26, 2013. Working near bodies crushed by rubble in a bullet-scarred, scorched mall, FBI agents continued fingerprint, DNA and ballistic analysis to help determine the identities and nationalities of victims and al-Shabab gunmen who attacked the shopping center, killing more than 60 people.
