ccs2023.jpgWe invite you to join us again for the Cold Case Symposium on October 12, 2023 at Purdue University to learn from experts and leave with action to support the families seeking answers in unsolved cases.

By joining us at the Cold Case Symposium 2023, you're not just enhancing your own skills—you're using the power of collective impact to align resources and mobilize support for unsolved cases. 

This year Dr. Krystal R. Hans in conjunction with Ryan Backmann (Project: Cold Case), will bring you the opportunity to:

🔬 Unleash New Techniques: Immerse yourself in sessions designed to equip you with best practices in forensic demonstrations and techniques to sharpen your skills and discover fresh approaches to analyzing evidence.

💡 Gain Insights from Experts: Thoughtful discussions with seasoned investigators, forensic scientists, legal professionals, families and compassionate victim advocates. Explore best practices, navigate ethical dilemmas, and gain a comprehensive perspective on cold case investigations.

🌐 Explore Digital Advancements: The latest breakthroughs in DNA analysis and digital forensics are being used to bring justice. Learn how to leverage these innovative tools for cold cases that were once deemed unsolvable.

🤝 Forge Lasting Connections: Collaborate with a diverse community of experts—some in professional training, others in lived experience as family advocates of the murdered and missing to expand your network and strengthen your resolve in seeking justice for families who are looking for resolution.

This event is offered in-person and online. To secure your spot, we recommend registering early as space is limited. Join us in making a positive impact together.

Join us for real stories, real support and real resources.
