Leila Briseno was 14 years old when she was reported missing from Riverdale, Illinois, with online missing-persons information stating that she was last seen on March 9, 2026. The publicly available details are limited, but the central facts that have been circulated are clear: Leila is a missing teenage girl, her disappearance was associated with Riverdale, and authorities were seeking the public’s help in locating her. Her case was listed with the National Crime Information Center under reference number M238877492, and it was also connected to National Center for Missing & Exploited Children case number 2080052.
The available online reporting does not provide a detailed account of the circumstances surrounding the moment Leila was last seen. It does not describe where in Riverdale she was last known to be, who she may have been with, what she was wearing, or whether investigators believed she may have traveled outside the area. That absence of detail leaves the case publicly defined by only a few essential points: a 14-year-old child was missing, the date tied to her disappearance was March 9, 2026, and the Riverdale Police Department was identified as the local agency to contact with information.
Because Leila was a minor, the involvement of the National Center for Missing & Exploited Children is especially significant. NCMEC describes itself as the nation’s nonprofit clearinghouse and comprehensive reporting center for issues involving missing and exploited children, and it directs families and the public to act quickly when a child is missing. Its public guidance says people should immediately contact local law enforcement and also reach NCMEC at 1-800-THE-LOST, the same national hotline listed in public notices about Leila’s case.
The public appeal in Leila’s case asked anyone with information about her whereabouts to contact the Riverdale Police Department at 708-841-2203 or the National Center for Missing & Exploited Children at 1-800-843-5678. That type of notice reflects how missing-child cases often depend on small pieces of information from people who may not realize what they know is important: a sighting, a message, a location, a vehicle, or a detail from the hours before or after the child was last seen. In Leila’s case, the online record provides no confirmed resolution marked as found alive or deceased, and no additional verified narrative has been made publicly available through the sources located.
Leila Briseno’s case is therefore a sparse but serious missing-child case out of Riverdale, Illinois: a 14-year-old girl last seen on March 9, 2026; a case entered under NCIC number M238877492 and NCMEC number 2080052; and a public request for information directed to Riverdale police and NCMEC. The known story begins with Leila being reported missing, continues through the effort to circulate her name and case identifiers online, and remains centered on the hope that someone with knowledge of her whereabouts will come forward. The overview of the case is that Leila Briseno, age 14, was last seen in Riverdale, Illinois, on March 9, 2026, and the publicly available information asks anyone who may know where she is, or what happened after she was last seen, to contact the proper authorities.
