DNA analysis is the best method to date of individualizing biological evidence. DNA analysis is conducted on biological material isolated from serological processing. Results are compared with known exemplars from victims and/or suspects and conclusions are drawn regarding the inclusion or exclusion of each individual. Statistical significance is calculated upon inclusion.
