Allycianna Auriela Santiago is a 16-year-old girl from Arnold, Maryland, whose name appears in public missing-child records maintained by the National Center for Missing & Exploited Children and related missing-child alert sources. One NCMEC-linked international poster lists her as an endangered missing child and states that she was last seen in Arnold, Maryland, on February 4, 2026.
That record identifies her as female, age 16, with brown hair and brown eyes, and it directs anyone with information to contact the National Center for Missing & Exploited Children at 1-800-THE-LOST or the Anne Arundel County Police Department at 410-222-8610.
The public information available about Allycianna’s disappearance is limited, which leaves much of the story without the fuller details families and communities often hope to understand. The NCMEC-linked record does not provide a detailed clothing description, a specific address, travel destination, or an account of the circumstances leading up to the moment she was last seen; it simply records that she was last seen in Arnold and that the case was treated as an endangered missing-child matter. In the absence of those details, the most reliable picture is a careful one: Allycianna was a teenage girl reported missing from Anne Arundel County, and the official call for help focused on locating her and encouraging anyone with information to reach law enforcement or NCMEC.
Public missing-child listings also show a later NCMEC poster for Allycianna Auriela Santiago, using a different NCMEC case number and NCIC number, which lists her as missing from Arnold, Maryland, as of April 30, 2026, and again states that she was last seen in Arnold. That later poster also describes her as a 16-year-old female and names the Anne Arundel County Police Department as the investigating agency, with the same local police contact number and NCMEC’s 24-hour call center listed for tips. A separate NCMEC RSS-style Maryland missing-children listing likewise includes Allycianna Santiago as missing from Arnold, Maryland, and directs anyone with information to the Anne Arundel County Police Department.
Because more than one public listing appears under Allycianna’s name, the available online record suggests that the case information may have been updated, reissued, or separately posted over time. The online sources do not provide enough detail to explain why the public dates differ, and they do not provide a narrative of what happened before or after she was reported missing. What is clear from the reliable public listings is that Allycianna was identified as a missing child from Arnold, Maryland, that she was 16 years old, that she was described as having brown hair and brown eyes, and that authorities asked the public to share any information with NCMEC or the Anne Arundel County Police Department.
For Allycianna’s family, friends, and the Arnold community, the case represents the fear and uncertainty that surrounds any missing-child report, especially when the public record contains only basic identifying details and very little about the circumstances. Maryland State Police guidance for missing-person cases emphasizes immediate reporting to local law enforcement, checking with people and places connected to the missing person, preserving possible digital evidence, and using official resources such as NCMEC, Maryland’s missing-person clearinghouse, and NamUs. In overview, Allycianna Santiago’s case is publicly documented as the missing-child case of a 16-year-old girl from Arnold, Maryland, with official listings asking the public to help by providing tips to NCMEC or Anne Arundel County Police, while the publicly available online information remains limited and does not explain the circumstances of her disappearance.Last Seen: Feb 4, 2026
