Wednesday marked 52 years since the body of a 15-year-old girl was found in rural Northern Colorado, and detectives are still trying to identify her killer. In November of 1973, hunters along the St. Vrain River in Platteville found the body of the teenager. However, it wasn't until 2023 that the girl, known as "Jane Doe 1973," was identified .

"We exhumed her to get DNA from her," said Byron Kastilahn, a cold case detective for the Weld County Sheriff's Office. "With new technology of genetic genealogy, we were able to identify some of these Doe cases including Jane Doe."
