In the winter of 2011, a young boy named Sebastian Lucas Conklin, who was five years old at the time, disappeared. He was a biracial male of White and Hispanic descent with brown hair and brown eyes, and a noticeable birthmark on his left calf. The last time he was seen was on December 3, 2011, in Hallandale Beach, Florida. Sebastian did not vanish alone; his younger sister, Briana Nikki Conklin, who was three years old, also went missing on the same day. The circumstances surrounding their disappearance point to a painful family situation, as authorities believe they were taken by their non-custodial mother, Marcela Conklin. Shortly after the children were reported missing, law enforcement began to investigate the case as a parental kidnapping. On December 5, 2011, a felony warrant for kidnapping was issued for Marcela Conklin. At the time of her children's disappearance, Marcela was thirty years old, described as a Hispanic female with brown hair and brown eyes. While the children were last seen in Florida, the case is being handled by the Fairfax County Police Department in Virginia, highlighting the multi-jurisdictional nature of the search. The investigation has led authorities to believe that Marcela may have taken her children, Sebastian and Briana, out of the country. The search for Sebastian and his sister has now stretched on for many years, leaving a void of unanswered questions for their loved ones. Authorities have received information suggesting that the children and their mother might be in the city of Cochabamba, in central Bolivia. This international aspect adds significant complexity to the investigation and the efforts to bring the children home. The case is a heart-wrenching example of a family abduction, where two young children were removed from their familiar surroundings. The core of this case revolves around the alleged actions of their non-custodial mother, leading to an extensive and ongoing search that crosses international borders, with the hope that Sebastian and his sister will one day be safely located.
