Independent professionals from every stage of a death investigation.

Meet the Team

NorthStar Forensic Consulting was founded by Ryan Jensen, a forensic consultant and death investigation specialist with more than two decades in Minnesota public safety and medical examiner systems.

Ryan Jensen Founder & Forensic Consultant

With more than 20 years of experience in public safety, forensic services, and death investigation, Ryan Jensen brings a unique combination of investigative experience, forensic knowledge, public safety leadership, and a genuine passion for helping people find answers.

Ryan's career has included serving as a Police Officer, Forensic Autopsy Technician, Medicolegal Death Investigator, and Senior Death Investigator, as well as Program Manager for the Minnesota Department of Public Safety's Minnesota VINE (Victim Information and Notification Everyday) program. Ryan also serves as a part-time death investigator for Anoka County. His NorthStar work is separate from his county role, and NorthStar does not accept matters connected to it. Throughout his career, he has worked closely with law enforcement, medical examiners, victims, families, attorneys, and public safety professionals. His experience includes participating in more than 2,000 autopsies and approximately 800 death investigations, giving him firsthand knowledge of the death investigation and medical examiner process—from initial response and scene investigation through autopsy, documentation, and the pursuit of answers within the available record. In 2025, Ryan received the Minnesota Department of Public Safety's Team Player Honorable Mention Award in recognition of his work supporting crime victims and their families following the Annunciation Church incident, including helping connect victims and families with valuable financial, mental-health, and other resources.

Ryan is also passionate about helping crime victims and families navigate complicated systems and find the resources they need. He understands that the death investigation process can be confusing, overwhelming, and filled with unfamiliar terminology. His approach is to take complex forensic and investigative information and explain it in simple, understandable language, so people can better understand what happened, what the process means, and what questions they may want to ask.

Above all, Ryan believes that working with families requires empathy, compassion, patience, and respect. Every case represents a person, a family, and a story, not simply a file or investigation.

Every stage of the process, seen from the inside

Ryan's roles trace the full arc of a death investigation:

  • Police Officer
  • Forensic Autopsy Technician
  • Medicolegal Death Investigator
  • Senior Death Investigator
  • Program Manager for the Minnesota Department of Public Safety's VINE program

That path put him at more than 2,000 autopsies and roughly 800 death investigations, standing at the same points where families, attorneys, and agencies later come looking for answers.

Building a Team of Experience

NorthStar Forensic Consulting was created around the belief that clients deserve access to experienced, independent, and objective professionals when they have questions about a case.

Ryan has assembled a team of professionals with extensive backgrounds in public safety, forensic investigations, death investigation, and related disciplines. Together, the NorthStar team can provide organizations, public safety agencies, law firms, and families with experienced perspectives when reviewing complex information and cases.

Our role is to examine the information available, identify relevant facts and issues, explain complicated findings in understandable terms, and provide a neutral, fact-based perspective.

We don't approach a case with a predetermined answer. We approach it with questions:

  • What do the facts tell us?
  • What information is available?
  • What may be missing?
  • What questions should be asked?

Sometimes a consultation may provide the clarity someone needs without additional services. Other cases may require a more comprehensive review or specialized expertise. When additional resources are appropriate, NorthStar can help identify the next step.

Our Mission

Whether we are working with a family trying to understand a loved one's death, a crime victim looking for resources, an attorney evaluating a case, or a public safety organization seeking an independent perspective, our goal is the same:

To provide experienced, independent, compassionate, and fact-based forensic consulting that helps people understand complex cases and move toward answers and clarity.
