Anne Arundel police used a genetic genealogy analysis to identify remains that were discovered more than 30 years ago, tying them to a man who they believe was killed in the 1960s.
Genetic genealogy can tie DNA to a family with a missing person or point to the likely identity of an individual whose DNA was found at a crime scene, according to the police. Police use this technology as a lead generation tool that helps investigators narrow the pool of suspects to a region, a set or families or an individual.
Wednesday police said they used the technology to identify remains found in 1985 when construction workers were clearing a lot to build Marley Station Mall. They believe the remains, which were found in a metal trash can, are that of Roger Hearne Kelso.
This type of testing uses autosomal DNA, which is inherited by both males and females, and can be used to compare any two individuals.
Genealogists compare DNA between two people combined with traditional genealogy research using historical records to infer their relationship. To do this, they look at hundreds of thousands of genetic markers from DNA samples, creating a genotype.
