Liandragianni Barbosa was 16 years old when she was reported missing from Somerville, Massachusetts, after being last seen on January 19, 2026. Publicly available online information identifies her as a teenage girl whose disappearance drew attention through missing-person notices shared beyond the immediate Somerville area. The available reports are limited, but they consistently center on the same essential facts: Liandragianni was last seen in Somerville, she remained missing after that date,
and authorities and child-safety organizations asked the public to help by sharing information that could assist in locating her.
As the case circulated online, the Somerville Police Department was reported to have confirmed that the Lexington Police Department was the lead agency handling the investigation. That detail suggests the search for Liandragianni involved more than one local jurisdiction, with Somerville connected to where she was last seen and Lexington identified as the agency leading follow-up efforts. Public notices also stated that she may still have been in the area, a phrase often used in missing-child alerts when investigators believe a missing young person could remain close to familiar communities, transit routes, friends, relatives, or other local connections.
The public-facing appeal in Liandragianni’s case was direct and urgent: anyone with information was asked to contact the Lexington Police Department at 1-781-862-1212, the Somerville Police Department at 1-617-625-1600, or the National Center for Missing & Exploited Children at 1-800-843-5678. The National Center for Missing & Exploited Children describes itself as a national nonprofit clearinghouse and comprehensive reporting center focused on missing and exploited children, and its public resources include missing-child poster searches and ways to report sightings or tips. In a case like Liandragianni’s, those contact points matter because even a small observation, a remembered conversation, or a confirmed sighting can help investigators understand where a missing child may have gone and who may have seen her.
Online information about Liandragianni Barbosa’s disappearance remains sparse, and there are no detailed public accounts in the reviewed sources describing the circumstances immediately before she was last seen, what she may have been wearing, who she may have been with, or whether investigators identified a specific destination. What is known publicly is the outline of a deeply concerning missing-child case: a 16-year-old girl disappeared from Somerville on January 19, 2026; local law enforcement and national child-safety resources were connected to the search; the Lexington Police Department was reported as the lead agency; Somerville police and NCMEC were listed as additional points of contact; and the public was asked to help bring forward any information. At its heart, the case of Liandragianni Barbosa is the story of a missing teenager whose name, age, last known location, and date last seen became the critical facts shared in hopes that someone, somewhere, could help bring her safely home.Last Seen: Jan 19, 2026
