Urgent Search Underway for Missing Women in Wyoming and South Dakota
Wyoming – An urgent search is being conducted for two missing women, Tuyen Pham and Linda Thacker, who disappeared under troubling circumstances in August 2025. Authorities are calling on the public for assistance in locating these individuals as search efforts intensify.
Tuyen Pham Missing Since August 10
Tuyen Pham, a 50-year-old woman, was reported missing after she was last seen on August 10, 2025, in Wyoming, near Clyde Park Avenue and 32nd Street SW. Her disappearance was formally reported to the police in September. Pham is classified as at-risk due to her need for prescription medication, which she currently lacks access to.
Pham is described as having a slim build, standing 5 feet tall, with black hair and brown eyes. The last known description of her clothing is unclear, and she does not have access to a vehicle, leading investigators to believe she is likely traveling on foot. There is no information regarding her potential destination, further complicating the search.
Authorities are urging anyone with information about Pham’s whereabouts to contact the Wyoming Police Department at (616) 530-7300 or submit tips anonymously via Silent Observer at (616) 774-2345.
Linda Thacker Missing Since August 18
Linda Thacker, a 65-year-old from St. Onge, South Dakota, was last seen by family members around 1 p.m. on August 18, 2025. The family attempted to contact her later that evening but received no response to a text message sent at 7:31 p.m. The Lawrence County Sheriff’s Office initiated a welfare check for Thacker on August 19, as concerns grew over her safety.
Her vehicle, a silver four-door sedan, was located in a remote area of the Black Hills, close to Beulah, Wyoming, near the South Dakota border. Thacker is characterized as being 5 feet 6 inches tall, weighing approximately 150 pounds, and was last seen wearing a blue shirt and jean shorts. Notably, personal belongings belonging to Thacker were discovered about 0.7 miles from her vehicle, raising concerns among search teams.
A coordinated search began on August 19, involving numerous agencies from both South Dakota and Wyoming. Search operations include specialized teams, such as K-9 units and aerial support using helicopters and drones, with efforts expanding over several days as new leads emerged. As of the morning of August 28, 2025, the search for Thacker remains ongoing, but to date, no trace of her has been found.
The circumstances surrounding her disappearance suggest she may not wish to be located. The search area is characterized as rugged terrain with dense vegetation, compounding the challenges faced by rescue teams.
Anyone with information on Linda Thacker’s whereabouts is encouraged to reach out to the Crook County Sheriff’s Office at 307-283-1225 or the Lawrence County Sheriff’s Office at 605-578-2230, as authorities continue the search for both missing women.
Background on Missing Persons Cases
Cases of missing individuals often bring communities together as they search for answers. In this instance, the situations of Pham and Thacker highlight the urgency and emotional toll on families when loved ones go missing. The authorities’ appeals for public assistance serve as a crucial component in the ongoing investigations, with the hope that increased awareness may lead to new information that could aid in the recovery of these women.
With two distinct cases emerging in nearby states, the focus remains on finding both Tuyen Pham and Linda Thacker and providing answers to their families during this challenging time.
