This pay-for-view article at FSI Genetics should be made free-share for a certain period of time. Its focus on touch-DNA transfer interpretations suggests that the current opinions on DNA circumstances are suspect and standards are lacking. This is a very important subject since police crime labs have a way of “spinning’ these DNA interpretations for a particular purpose.

Highlights

Understanding the variables impacting DNA transfer is highly relevant
DNA transfer awareness is required to limit contamination risk
Dedicated training is required for experts providing opinion on DNA transfer
More research is required to generate probability estimates for more situations
