"National DNA Day is a special day when teachers,
students, and the public can learn more about genetics and genomics. The
National Human Genome Research Institute (NHGRI) at the National
Institutes of Health has sponsored DNA Day for the past ten years, to
commemorate the completion of the Human Genome Project in April 2003 and
of Watson and Crick's discovery of the double helix structure of DNA..."

It’s More Complex than You Think:A Chief’s Guide to DNA
"The U.S. Justice Department’s Office of Community Oriented Policing Services (COPS) and the Police Executive Research Forum (PERF) are pleased to issue this law enforcement executives’ guide to the use of DNA evidence in criminal investigations.
Every day, DNA evidence becomes more useful, not only in the identification and prosecution of criminal offenders, but also in ruling out innocent persons and in some cases exonerating persons who have been falsely convicted. Once a tool used mainly in cases of homicide, sexual assault, and other violent crimes, DNA increasingly is being used in the investigation of property crimes as well.
Furthermore, scientists continue to make advances in the technology of DNA testing, allowing useful information to be produced even in cases where DNA samples from crime scenes are extremely small or degraded.
However, the rapid expansion in the use of forensic DNA has come at a price: large backlogs of evidence wait to be tested in many jurisdictions.
This book is a practical guide that aims to help police chiefs and other law enforcement executives manage their DNA testing needs and capabilities, as they look forward to ever-increasing demand for DNA evidence in coming years. With support from the COPS Office, PERF
gathered information for this book by interviewing police chiefs, crime lab directors, and other experts in this field; conducting site visits to DNA labs; surveying law enforcement agencies; and holding an Executive Session in September 2009 to discuss the challenges facing police
executives regarding DNA evidence..."

Review of the Federal Bureau of Investigation Laboratory’s Forensic DNA Case Backlog
"...The FBI Laboratory’s backlog in analyzing and uploading convicted offender samples is mainly caused by recent federal legislation that expanded the scope of DNA sample collection from violent convicted federal offenders to include anyone who commits a federal offense as well as non-U.S. citizens who are detained in the United States.2 State and local forensic laboratories are also experiencing backlogs in analyzing and uploading convicted offender DNA samples. Among other measures, the backlogs at the state and local level have prompted the federal government to initiate grant programs to reduce the number of backlogged convicted offender samples nationwide. According to the FBI, at its height in 2009, the convicted offender sample backlog contained over 300,000 samples.
Legislation that expanded the scope of DNA collection includes the 2001 U.S. Patriot Act, which added qualifying offenses to the collection of DNA samples from convicted offenders; The Justice for All Act of 2004, which expanded the offenses for convicted offenders to include any federal offense; and The DNA Fingerprint Act of 2005, which directed that the Attorney General may collect DNA samples from individuals who are arrested or from non-United States persons who are detained under the authority of the United States. 3 For example, the Department of Justice’s Convicted Offender DNA Backlog Reduction Program provided $32 million in grant funding from fiscal years 2005 to 2009 to help states reduce the backlog of convicted offender DNA samples. According to the FBI, the number of convicted offender samples received rose from 7,833 in 2004, to 73,635 in 2005, to 99,215 in 2006, to 75,294 in 2007, to 76,932 in 2008, and 96,973 in 2009. Despite the increase in the number of convicted offender samples that are collected, the FBI Laboratory has reduced the size of its convicted offender backlog by implementing automated processes to analyze the samples. In addition, the FBI stated that it was able to reduce the backlog by shifting between 5 and 9 casework positions to address the skyrocketing convicted offender demand. As a result, the FBI Laboratory anticipates eliminating the convicted offender backlog completely by September 2010..."
