Using a 51-year-old DNA sample, bones 9-year-old Debbie Lynn Randall, has been identified.

"DNA Labs International quickly found distant relatives in the GEDMatch Pro and FamilyTreeDNA databases using the SNP profile developed with the Forenseq Kintelligence System. The family tree pointed to the Rose family, and they cooperated by providing a sample DNA for comparison. The DNA left on Randall’s body and the comparison familial DNA was consistent. William B. Rose was the likely culprit.But William Rose committed suicide in 1974, just two years after the crime. So, investigators received permission to exhume the body. DNA Labs International then did STR confirmation on the exhumed remains per the DOJ interim guidelines to ensure the DNA recovered from the scene was a match to William Rose. It was."
