After 33 years, missing woman identified in Bone Lake murder case
DNA Doe Project testing and a family DNA match identified the remains after more than 30 years, prompting investigators to reopen the cold case.
On Friday, authorities identified the "Bone Lake Jane Doe" as Denise Elaine Sexton Hartley, a 27-year-old mother who disappeared from St. Paul in 1993, ending a nearly 33-year mystery.
The case began on June 12, 1993, when Washington County Sheriff's Office investigators discovered a decapitated head near Bone Lake in New Scandia Township, followed shortly by a severed foot in the Mississippi River.
Detective Clayton Evens collaborated with the DNA Doe Project to secure funding and analyze samples, successfully matching DNA from the remains to Hartley's daughter after decades of uncertainty.
Evens described the identification as a "sigh of relief," while investigators are now rebuilding a timeline of Hartley's final days and interviewing friends and acquaintances to determine who killed her.
Although identified, the mystery of the perpetrator remains unresolved, as Hartley was not on the sheriff's radar as a missing person when she disappeared, complicating the decades-old investigation.
