Patricia Barrett (2 of Hearts, Utah)

When Patricia “Patti” Barrett got on a bus from Dallas to Salt Lake City in 1978, her family had no way of knowing they’d never see her again. For over 30 years they were left wondering what happened to Patti, until 2012, when, with the help of Patti’s daughter and DNA testing, Salt Lake County detectives were able to connect her to the remains of a 1978 Jane Doe. Nearly 12 years have passed since that identification, and investigators are still trying to figure out what happened to Patti, and who’s responsible for her death.
