The infant’s body was exhumed in September 2009 after Webb learned that DNA could be extracted from bones and tissue. North Texas University Science Center conducted lab tests on the DNA that was extracted from the infant's remains, but no matches were found.
In 2019, police submitted the DNA to a Virginia-based genetics genealogy company, which found two potential matches.
Using those genetic links, police were able to use a family tree that led to Theresa Bentaas. Investigators found DNA in trash they seized at Bentaas’ house that could not exclude her as the biological mother, according to a court documents.
Bentaas is scheduled to be sentenced Dec. 2 at the Minnehaha County Courthouse.
