Duration: 1.5 hour(s)

This webinar will build on the concepts presented in the webinar “The Time to Collect is Now: DNA Evidence in Groping Sexual Assault Cases” presented by Dr. Julie Valentine. The presenter will discuss evidence collection and packaging for trace DNA, laboratory workflow, validation studies, and clean techniques to use when collecting or working with DNA.

The presentation will begin with a review of the case study and evidence collection concepts presented by Dr. Julie Valentine in the webinar “The Time to Collect is Now: DNA Evidence in Groping Sexual Assault Cases” presented on February 27, 2019.  We encourage participants to watch this webinar first to have a good foundation for what will be covered in the second webinar.  However, they may be watched independently of each other.

The foundation for this webinar is rooted in the many questions regarding lab processing of casework DNA samples that were asked during Dr. Valentine’s original presentation. This second webinar will target a multi-disciplinary audience and cover some basics of forensic DNA analysis and interpretation.

The presenters will discuss methods and clean techniques that are necessary for collecting and packaging trace DNA evidence.  Additionally, the presenter will describe clean techniques and laboratory set up to help prevent contamination when working with trace amounts of DNA.

The general steps of forensic DNA laboratory workflow will be covered, including extraction, quantitation, normalization, amplification, DNA separation and detection, and interpretation.  The presenters will also talk about the role validations play in helping determine the capabilities of the laboratory workflow and interpretation.  Knowing your equipment and how it functions with samples of all types is important for developing standard operating procedures for processing and interpreting DNA samples with low amounts of DNA.

Funding for this Forensic Technology Center of Excellence event has been provided by the National Institute of Justice.
