Tyler Blake Weathersby, 31, of Sioux Falls, South Dakota, was last seen on the morning of September 4, 2024. Weathersby left his home in western Sioux Falls around 7:15–7:45 a.m. for a walk, a routine he followed several times daily. Surveillance footage placed him near the intersection of West Madison Street and North Marion Road, close to Interstate 29, at approximately 7:50 a.m., walking east; the footage showed him speaking briefly with a boy on a bicycle and approaching the driver of a silver Hyundai Santa Fe stopped in the street. He did not return home. His wife, Monalisa Perez, reported him missing to the Sioux Falls Police Department that afternoon after searching the neighborhood on her own. Weathersby left his cell phone, wallet (including ID and credit/debit cards), and passport at his residence. He was last seen wearing a white T-shirt, black shorts, a tan beanie, and dark-colored athletic shoes. He is described as a Black male, approximately 6'0" tall and 155 pounds, with a shaved head and brown eyes at the time of disappearance.
