Case Details:Delilah White Dress, a 63-year-old American Indian/Alaska Native woman residing in the Pine Ridge community on South Dakota's Pine Ridge Indian Reservation, was first publicized as missing by the Oglala Sioux Tribe Department of Public Safety in a social media post in early May 2025, which stated she had likely been missing for one to two months. The South Dakota Missing Persons Clearinghouse separately lists her date of last contact as March 5, 2025. No last-seen location within Pine Ridge, witness account, or clothing description has been publicly released. She is described as approximately 5 feet 5 inches tall and weighing about 170 pounds, with brown hair and brown eyes; officials believe she may be using a wheelchair. No personal effects tied to her disappearance have been publicly documented.

The Pine Ridge Oglala Sioux Tribal Police Department is the lead investigating agency, and White Dress's case is listed with the South Dakota Missing Persons Clearinghouse. Following the initial report, investigators contacted a close friend of White Dress living in Nebraska, who told police she had not seen her. In July 2026, Medicine Wheel Ride, a nonprofit that supports families of missing and murdered Indigenous relatives, publicly renewed a call for information about her whereabouts and asked the public to share awareness posts about the case. No suspects or persons of interest have been publicly named in connection with her disappearance, and no arrests have been made. As of this writing, more than a year after she was first reported missing, no public update on White Dress's whereabouts has been released, and her case remains open. Anyone with information is asked to contact the Pine Ridge Oglala Sioux Tribal Police Department / OSTDPS Dispatch at 605-867-5111.
