For twenty years, she was Jane Doe Number Six. Found in two separate locations — Manorville in 2000, Ocean Parkway in 2011 — nobody reported her missing, nobody came forward, and nobody connected her death to the Gilgo Beach investigation until genetic genealogy gave her back her name in 2020. Rex Heuermann was charged with her murder four years later. He has since pleaded guilty. This look back puts Valerie Mack's life first. She was born into loss — placed in foster care as a child, adopted by the Mack family, estranged from her own son by her early twenties. She was working in Philadelphia when she vanished. The system failed her before she ever crossed paths with whoever killed her. And after her death, it took two decades of silence before science caught up. The evidence prosecutors laid out is specific: a female hair on Valerie's remains matching DNA profiles of Heuermann's wife and daughter — his daughter who would have been a toddler at the time. A 2003 newspaper with an article about Valerie's remains, found in Heuermann's possession, described by prosecutors as a souvenir. And entries in the planning document recovered from his computer — including a section with notes on preparation that matched the condition in which Valerie's remains were found. Heuermann pleaded guilty to her murder as part of the agreement covering seven victims, and admitted to an eighth. We revisit where the case stood at the time of our reporting. Twenty years without a name. This segment gives her one.
