  • Discover more about forensic entomology, from Krystal’s early love of insects to the crucial job experts like her have when collecting evidence at crime scenes
  • Hear more about Krystal’s roles leading Hans Lab, where she collects and analyzes insect evidence and mentors students, and Hans Forensics, where she consults on current investigations
  • Gain knowledge about student experiences with real Indiana cold cases in Krystal’s popular forensic investigation class — which has grown to over 200 students — and how their contributions can change the trajectory of investigations
  • Understand more about society’s fascination with true crime and the importance of empathy and ethical advocacy for victims and their loved ones
