  1. Solutions for DNA backlogs Peter M Marone Virginia Department of Forensic Science Texas Forensic Science Seminar October 7-8, 2010

  2. What is a backlog? • Not a backlog until over 30 days old • “If it’s in the lab, it’s backlog” • Police property room vs in the lab • Makeup of the cases

  3. With all effort and funding expended, why is there still a backlog? • Demand for DNA testing is increasing • ySTR • Property crime • Touch DNA • Increased number of samples comprising each case • Expansion of data bases to include arrestees and misdemeanors

  4. Exhibit 1.DNA casework trends: Supply, demand, backlogs

  5. Expansion of database samples • Over the last several years, the number of eligible crime types has increased • Arrestee testing begun in 2003 and crime types expanded over the years • Commitment to supporting resources at the same time as expanding databases is required.

  6. Exhibit 4.DNA database backlog trends from 2007-2008

  7. Evidence in law enforcement custody • Investigation shows the evidence is not probative • Charges dropped • Guilty plea already made • Case may be unfounded
