Dental Records are the number one way a burned body is identified. If dental ex-rays cannot be found, the next step is DNA testing. There are are several ways DNA can be detected. The first is an extraction near a tooth or from bone marrow. Skulls of burn victims are generally left in tact as well. Thus, the brain is typically in fairly good shape. Accordingly, blood can be extracted from the brain. Once authorities get a sample, they must have a comparison sample. This can be taken from a toothbrush, or a hairbrush. A comparative analysis can also be conducted on relatives blood — this is not as simple and less efficient.
