I assume PCR is involved. If so, are long, specific primers used or shorter, less specific primers (DAF) used? Or perhaps restriction fragment length polymorphisms (RFLP) would work best? Do techniques vary between different agencies and departments? I’m not planning anything, (seriously) just wondering.

Any type of organism can be identified by examination of DNA sequences unique to that species. Identifying individuals within a species is less precise at this time, although when DNA sequencing technologies progress farther, direct comparison of very large DNA segments, and possibly even whole genomes, will become feasible and practical and will allow precise individual identification.
To identify individuals, forensic scientists scan 13 DNA regions, or loci, that vary from person to person and use the data to create a DNA profile of that individual (sometimes called a DNA fingerprint). There is an extremely small chance that another person has the same DNA profile for a particular set of 13 regions.
