This week’s post is going to be a fairly short one. One of the things that I believed when I first started getting into investigative genetic genealogy (IGG), and especially on the bioinformatics side of things, was that a file with more SNPs was going to provide better results than one with less SNPs. My […]

This week’s post is dedicated to exploring the differences between clinical and forensic samples, specifically relating to obtaining data for investigative genetic genealogy purposes. In a clinical setting it’s usually relatively straightforward to obtain high quality samples for DNA sequencing, as you generally have a living, breathing person in front of you. One might take

This week I’d like to change gears a bit and do a bit of a case study – something I plan to do more of in the future. The case I’ll be covering today is one that I worked on through the DNA Doe Project, Hudson John Doe 2019. This is a case I was

One of the first hurdles an investigative genetic genealogy (IGG) professional faces when taking on a new case, is determining how to get a file that can be uploaded to GEDmatch / FTDNA, from the evidence available. This evidence could be anything from swabs from a sexual assault kit, to blood stains, or even human

Throughout the last 3.5 years or so, I am proud to have assisted in resolving dozens of law enforcement cases through the use of investigative genetic genealogy (IGG). In some instances, such as the Lavender Doe case (covered excellently here), I have led teams of extremely dedicated volunteer genetic genealogists at the non-profit DNA Doe
