Demand for DNA testing is increasing Demand for DNA testing is increasing ySTR ySTR Property crime Property crime Touch DNA Touch DNA Increased number of samples comprising each case Increased number of samples comprising each case Expansion of data bases to include arrestees and misdemeanors Expansion of data bases to include arrestees and misdemeanors
