Harold Dean Clouse Jr. and Tina Linn Clouse, formerly known as the Harris County Does, were a pair of formerly unidentified murder victims found outside of Houston, Texas in January, 1981. After moving in the summer of 1980 with their infant daughter, Holly Marie, from Volusia County, Florida to Lewisville, Texas, the Clouses stopped contacting their families in October, 1980. Their remains were found in a wooded area north of Houston on January 12, 1981. The bodies were found within feet of each other, both significantly decomposed, with a post-mortem interval of approximately two months. Dean Clouse had been bound and beaten to death, and Tina Clouse was strangled. Holly Marie’s remains were not found with or near her parents' remains. After the two bodies were not identified and the case grew cold, they were buried in anonymous graves, where they remained unidentified for 41 years. In 2011, the Clouses’ bodies were exhumed for genetic testing. In 2021, forensic genealogists positively identified the Harris County Does as Dean and Tina Clouse, however, Holly Marie’s whereabouts remained unaccounted for. In 2022, Holly Marie was located alive in Oklahoma, with no memory of the traumatic events of her infancy.

Michelle Angela Garvey was an American teenage girl murdered in Texas within a month of running away from her home in Connecticut. Her body was quickly found but remained unidentified until a 2014 DNA test, after an amateur Internet researcher suggested a match between the Texas unidentified decedent and Connecticut missing-person data.
