The Time to Analyze is Now: DNA Evidence in Groping Sexual Assault Cases

Event Dates
All times are Eastern Time unless noted otherwise.
Event Duration
90 minutes

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.
