Conducted by New Zealand's Institute of Environmental Science and Research (ESR), the survey also shows that STRmix evidence was presented in more than 80 successful admissibility hearings worldwide double the survey number reported the year before.

Key Points: 
  • Conducted by New Zealand's Institute of Environmental Science and Research (ESR), the survey also shows that STRmix evidence was presented in more than 80 successful admissibility hearings worldwide double the survey number reported the year before.
  • Dr. Buckleton notes that STRmix has proven to be highly effective in producing usable, interpretable, and admissible DNA results in a wide range of criminal cases, including violent crime and sexual assault cases.
  • There is also a desire for more advanced probabilistic genotyping and foundational likelihood ratio (LR) training, demonstrating that STRmix users want a more in-depth understanding of STRmix principles.
  • A new version of STRmix, STRmix Version 2.8, was recently launched following nearly a year of extensive development and testing.
