DNA typing is used for paternity or criminal cases, there is almost always a
body available in addition to an eyewitness or confession from the accused.
Although there have been successfully prosecuted murder cases in which a body
was not found, very few cases exist where there was no eye witness or confession
in which DNA played an integral part.
fingerprinting consists of two major components: DNA analysis for matching
purposes followed by statistical analysis to determine the probability of a
match occurring by chance alone.
Provided that the testing laboratory has followed the practiced standards in the field of forensic DNA typing, there is no reason to doubt the accuracy of the results obtained.
