It took mere hours to confirm that the person killed in a compound near Pakistan's capital was Osama bin Laden. Officials compared the DNA of the person killed at the Abbottabad compound with the bin Laden "family DNA" to determine that the 9/11 mastermind had in fact been killed, it was not clear how many different family members' samples were compared or whose DNA was used. Among the five killed in the compound, one of them was one of bin Laden's adult sons, Also to identify bin Laden, a visual ID was made. There were photo comparisons and other facial recognition used to identify him, there was full biometric analysis of facial and body features.
According to the U.S. Human Genome Project which helped to identify the more than 20,000 genes in human DNA forensic experts use DNA to distinguish a person's genetic footprint, by looking for matches from a sequence of small, repeating markers at different locations on the person's genome. Each of us has a unique genetic fingerprint, even though only one-tenth of 1 percent of the 3 million DNA bases differs from one person to the next.
Facial recognition software programs compare photographs of the person. Such programs take the topology of the face and essentially read the features, where the person's eyes, nose, lips are located, their proportions and measurements. The facial recognition programs map the geometry of a person's face and can compare images.
He's a distinctive person, for that part of the world; He’s 6-feet, 4-inches. He's gaunt. There are plenty of photographs of him.
