In the trauma surrounding mass disasters, the need to identify victims accurately and as soon as possible is critical. DNA identification testing is increasingly used to identify human bodies and remains where the deceased cannot be identified by traditional means. This form of testing compares DNA taken from the body of the deceased with DNA taken from their personal items (e.g. hairbrush, toothbrush etc.) or from close biological relatives. DNA identification testing was used to identify the victims of the terrorist attack on the World Trade Center in New York on September 11, 2001, and of the victims of the Tsunami that hit Asia on December 26, 2004. Shortly after the 9/11 attack, police investigators asked the victims' families for personal items belonging to the missing, and for DNA samples from family members themselves. The New York medical examiner's office coordinated the DNA identification testing program; however, some of the identification work was contracted out to private laboratories.
