A little girl disappeared with the person she trusted most.
Her mother.
What began as a custody dispute soon became an international missing child case.
More than two decades later, authorities believe she may still be in Russia.
Anastacia Marie Argentova Stevens was a young girl living in Pembroke Pines, Florida. She had blond hair, blue eyes, and pierced ears. Like any child, she deserved a safe and stable childhood surrounded by the people who loved her.
Instead, she became the subject of an international parental abduction investigation.
On April 23, 2003, Anastacia was allegedly taken by her mother, Victoriya Argentova. According to investigators, the removal violated custody arrangements, and authorities believe the pair may have travelled to Moscow, Russia.
When Anastacia was not returned as expected, her disappearance was reported to law enforcement. Investigators quickly began working with missing child agencies and international partners to determine where she had been taken and whether she was safe.
Unlike stranger abductions, parental abduction cases are often especially challenging. The child is usually with a parent, but the removal can leave the other parent without any legal access or knowledge of the child's whereabouts. When international borders are crossed, locating and returning a child can become even more difficult because different countries have different legal systems and custody laws.
Authorities believe Anastacia may have remained in Russia for many years. As time passes, missing children in international cases may grow up under new identities, attend different schools, and build lives without knowing that they are the subject of an active missing persons investigation.
According to investigators, the suspected motive was related to a parental custody dispute. In many international parental abduction cases, one parent chooses to leave the country with a child in an effort to retain custody or avoid legal proceedings. Investigators have not publicly alleged any other motive beyond the unlawful removal of the child.
Despite the years that have passed, Anastacia's case remains open. Age progression images and public awareness continue to play an important role in the hope that someone may recognize her or provide information about where she is living today.
Anastacia was only a little girl.
She had no control over the decisions made by the adults around her.
Her disappearance is a reminder that parental abduction can have lifelong consequences, separating children from family members, friends, and the lives they once knew.
Authorities continue to encourage anyone with reliable information about Anastacia's whereabouts to contact law enforcement. Until she is located, her loved ones continue hoping that one day she will learn the truth about her past and be reunited with the family who has never stopped searching for her.
