Hello to everyone who is planning on attending the 2017 AAFS Criminalistics II sessions at the Annual Scientific Meeting in New Orleans. Have you ever wondered whether it’s more appropriate to search more loci or a larger haplotype database to get a Y-chromosomal Short Tandem Repeat (Y-STR) statistic? Want to talk about what the transposed conditional is and how to avoid it? What about an opportunity to ask for tips on conveying DNA results to a jury? As a departure from the normal presentation format, we are holding panel discussions on Thursday, February 16, and Friday, February 17. These sessions are intended to be an opportunity for community dialog on some current issues.
The Thursday afternoon topic is Y-STR interpretation and statistics. The discussion will revolve around interpretation of single source and mixed Y-STR haplotypes, the Scientific Working Group on DNA Analysis Methods (SWGDAM) Y-STR interpretation guidelines, various Y-STR statistical approaches, application of Y-STRs in casework, and presenting Y-STR results in court.
The Friday morning topic is DNA testimony and how the focus of expert witnesses on DNA analysis has changed since the early 1990s. The discussion will cover the different perspectives of the jury, the advocates, and the court; particularly, as they relate to the significance of DNA (its presence or absence), the meaning of an inclusion, exclusion, and “inconclusive,” and the ability to answer questions about how DNA was left behind.
Please join us for interactive and productive conversations. I encourage you to come prepared with questions for the panelists.
