Briana Conklin was 3 when she and her 5-year-old brother Sebastian were reported missing from Hallandale Beach, Florida, on December 3, 2011. Investigators say the siblings were taken by their non-custodial mother, Marcela Conklin, who had a felony kidnapping warrant issued December 5, 2011. Authorities believe Marcela fled the country with the children, and Cochabamba, Bolivia, is considered the most likely location.

At the time of the disappearance Briana was described as biracial Hispanic/White, with brown hair and brown eyes, about 3 feet tall and 35 pounds; her ears were pierced. Sebastian was also described as biracial, with brown hair and brown eyes, about 3 feet 6 inches tall and 40 pounds, with a birthmark on his left calf. Fairfax County, Virginia police have been overseeing the search because the family had prior connections to Virginia. The children’s whereabouts remain unknown.

If anyone has information about Briana or Sebastian’s location or remembers seeing them or Marcela Conklin around late 2011, please contact the investigators handling the case.
