"Decades-Long Mystery Solved: Missing Iowa Teen's Identity Confirmed after 46 Years"

After 46 years, the remains found in the Mississippi River in 1978 have been identified as those of 15-year-old Helen Renee Groomes from Iowa, who disappeared from Ottumwa. DNA evidence and scientific investigation led to the identification, and the Wapello County Sheriff's Office has opened a new investigation into her death. The body was initially classified as "Lincoln County Jane Doe" and buried in Missouri, but recent forensic analysis and DNA sequencing helped track down Groomes' brother, leading to the identification of the victim.
