[Verse 1] From eighty-seven to ninety's end A shadow haunted Interstate Four women lost, their lives cut short At motels sealed by cruel fate The killer left his DNA behind But databases came up dry For decades families wondered why No justice could be satisfied [Chorus] Genetic genealogy finds the way Through family trees where secrets lay Database matching, graph traversal too Connecting dots from me to you When DNA tells the family story Science solves what time made blurry Algorithms trace the bloodline back Following each genetic track [Verse 2] Twenty-twenty-two brought hope renewed With genealogy's digital might They took that sample from the scene And searched through millions in the night Not looking for exact matches now But relatives both far and near The algorithm's patient power Made distant family connections clear [Chorus] Genetic genealogy finds the way Through family trees where secrets lay Database matching, graph traversal too Connecting dots from me to you When DNA tells the family story Science solves what time made blurry Algorithms trace the bloodline back Following each genetic track [Bridge] Graph traversal walks each branch From cousin to cousin, aunt to nephew Sequence alignment confirms the truth When patterns match what science knew Harry Greenwell was the name Though death had claimed him years before The families finally learned the truth That algorithms could restore [Verse 3] They dug him up to test his genes Sequence alignment proved the case The I-65 Killer's reign of fear Now had a name, now had a face Though justice came too late for him The families found their peace at last When algorithms bridged the gap Between the future and the past [Final Chorus] Genetic genealogy finds the way Through family trees where secrets lay Database matching, graph traversal too Connecting dots from me to you When DNA tells the family story Science solves what time made blurry Algorithms trace the bloodline back Following each genetic track [Outro] The highway's quiet, cases closed But science keeps its vigil true For every mystery yet unsolved There's an algorithm breaking through
