Lette Birn has been active in K9 SAR since 1989.
In the summer of 1989, while volunteering at a local wilderness search with her endurance horse, she came across a K9 team, went home, ordered a bloodhound puppy, joined a local SAR team and discovered a new passion: K9 SAR.

Countless nationwide training seminars, disaster deployments and wilderness searches later, Lette is currently working two black labs, Finnegan and Piper. Finn certified with FEMA as a live find dog and later with our local K9 team Mountain Canine Corps as a wilderness airscent dog.
Piper is certified with Mountain Canine Corps in Human Remains Detection.
Lette has attended a number of HRD training seminars with Piper in Arizona, Colorado and Texas.
Lette and Piper joined Colorado Forensic Canines in 2016.
From 1993-2016 Lette was a member of the New Mexico Task Force One FEMA team as a K9 handler and had three certified FEMA live find dogs. She acted as the Canine Coordinator for the task force 2007 – 2016 and was a FEMA K9 evaluator.
Deployed to the Pentagon for 9/11, and to Hurricanes Katrina and Rita with NM-TF1.
Lette has participated in hundreds of wilderness searches with MCC over the years, both live find and HR.
Being self-employed - and having an extremely supportive husband - has allowed Lette to embrace the K9 SAR lifestyle with lots of hours spent in the mountains, on disaster sites or at trainings throughout the country.

Lette Birn was born and raised in Denmark, attended college and taught school in Germany after marrying Joachim, her German husband.  In 1980 they moved to Los Alamos, NM with their twin sons – “for one year”.  35+ years later they are still in love with outdoor life in New Mexico.
Avid skiers, the entire family was active as volunteer patrollers with the National Ski Patrol for 15-some years. Lette taught and organized the Outdoor Emergency Care course for Pajarito Ski Patrol for several years.

I discovered an interest for ground-penetrating radar during my undergraduate studies at the University of Denver about 2 years ago. It's ability to quickly, accurately, and non-destructively collect and present data is fascinating and an incredibly powerful technique that always has my interests peaked. My focus lies in using the GPR system for its forensic abilities, and I have worked on a variety of projects including assisting police departments on investigations, with historical and private cemeteries to locate lost burials, as well as simply looking for lost graves. It is also always a great pleasure to team-up with these fascinating dogs when we face difficult, large terrain. Please feel free to contact me with any questions you may have regarding ground-penetrating radar, or if you need to figure out whether it would be appropriate to use this service on your project.

I spent 31 years teaching teenagers and am currently retired. Some of my current time is spent supporting Colorado Forensic Canines in the capacity as Field Support along with driving the search boat for the group.

I have also trained 4 dogs to Schutzhund titles which includes tracking and obedience as part of the requirement. Because I have spent the last 30 years training dogs as a hobby, I understand the intricacies of training tracking, and the difficulty of the task. I currently serve as Western KG Secretary for the dog organization of DVG.

In addition, my love of the outdoors has instilled in me a confidence in the wilderness. Since I am an avid hiker it helps with physical conditioning, as well as, a healthy respect for Mother Nature. Colorado outdoor activities have been my passion for years. These qualities are needed in a person supporting the dog teams in outdoor searches.

My interests include hiking, climbing, mountaineering, canyoneering, and snow sports, and I've had the good fortune to be able to do extensive back country travel, a great deal of it with map and compass prior to GPS availability for civilian use. In 2003, I wanted to learn how to use these new tools and started geocaching as a way of getting familiar with the new technology. Since then the “Geocaching Game” has become an end in itself – it's taken me to many interesting places which I would not have discovered otherwise, and back to some favorite areas that I had not visited in a long time.


I have climbed all of the 14,000' peaks in the lower 48 states and all peaks above 13,000' in Colorado and Utah, and have through hiked two long distance trails. I believe that being comfortable in rough terrain, both above and below timberline, and my experience in living outdoors and working through the logistics required to do these things are assets that I can bring to the CFC group.

I'm an avid wanderer and naturally curious soul. My background is in geology as a profession and rock collecting as an addiction.  I also enjoy the occasional long trail run or off-trail excursion. All of these passions, along with an innate appreciation of the canine world, resulted in a serendipitous joining of the CFC circle in 2015. I live in Conifer with my wife Aspen, two squirrely young boys and three dogs.

Silvia Pettem

Silvia Pettem is a self-employed researcher, author, writer, and public speaker with a passion for researching cold cases, unidentified remains, and longtime missing persons. She spent the first two decades of her career doing historical research and writing for individu­als, businesses, and local governments. Then, in 1996, her life took a new turn when she stumbled upon the gravestone of a Jane Doe––a murder victim from 1954.

A few years later, she applied her research skills to both old-fashioned detective work and the power of the Internet by entering into a successful partnership with her local sher­iff and with forensic experts of the Vidocq Society to determine the young woman’s identity. She chronicled their work in her book, Someone’s Daughter: In Search of Justice for Jane Doe.

Now an associate member of the Vidocq Society and one of its Medal of Honor recipients, Silvia is an American Investigative Society of Cold Cases consulting committee member, a volunteer in the Detectives Section of the Boulder Police Department, an advisory board member (and social media coordinator) of the organization Families of Homicide Victims & Missing Persons, and a NamUs instructor in classes sponsored by the Colorado Bureau of Investigation.

She wrote her latest book, Cold Case Research: Resources for Unidentified, Missing, and Cold Homicide Cases, in order to aid other investigators as they grapple with cold cases of their own. Silvia can be reached at or via her website,
