Tammy Elizabeth Stubblefield went missing on December 6, 2019. She was last seen walking down the street on Moore Avenue, away from her neighborhood in Walhalla, South Carolina. She has never been heard from again.

For unclear reasons, she wasn't reported missing until January 29, 2020, nearly two months after her disappearance. The authorities are investigating if her disappearance is related to some or all of the cases of missing persons Pamela "Faith" Roach, Laura Anders, and Scott Ivester, and the death of Renee King. Roach and Anders disappeared from the area in 2019 and Ivester in 2021; they have never been found. King disappeared in November 2020, and her body was found in a wooded area along Rufus Land Road in February 2021. Similarities in the cases and mutual friends and acquaintances are being investigated but it is unclear if the cases are connected. All the cases remain unsolved.
