Millie Moore is a 16-year-old girl from Illinois whose name appeared in online missing-child listings after she was reported missing from South Holland, Illinois, with a missing date of January 21, 2026. The National Center for Missing & Exploited Children listing indexed for that South Holland case identified the investigating agency as the South Holland Police Department and listed NCMEC case number 2075113, with the NCMEC 24-hour call center also attached to the public notice. The online information available for that January South Holland listing is limited, and the public record does not describe the circumstances of where Millie was last seen, what she may have been wearing, who she may have been with, or what led authorities and loved ones to believe she was missing.
The available online record portrays the case in the stark and painful way many missing-child alerts do: a young person’s name, age, city, date, and contact information, with few personal details released publicly. Millie was listed as female and 16 years old, and the South Holland notice directed anyone with information to contact local police or NCMEC. Because the public alert did not provide a fuller timeline, the most responsible account is that Millie’s disappearance was publicly documented through missing-child resources, but the exact sequence of events surrounding the January 21, 2026 South Holland report remains unclear from available online sources.
Later online records show another NCMEC poster for a Millie Moore, also age 16, listed as missing from Matteson, Illinois, on March 24, 2026, under a different NCMEC case number, 2083062, with the Matteson Police Department named as the contact agency. That later poster states that Millie was last seen on March 24, 2026, and provides the Matteson Police Department phone number along with NCMEC’s 24-hour hotline. A separate missing-persons aggregation page also repeated the March 24, 2026 Matteson listing and the Matteson Police Department contact information.
The existence of the later Matteson listing means the public online record is not simple: one indexed NCMEC result refers to Millie Moore missing from South Holland on January 21, 2026, while a later active NCMEC poster refers to Millie Moore missing from Matteson on March 24, 2026. The earlier South Holland poster page was not available when opened, and the Global Missing Children Network page for the same South Holland-linked case number indicated that a missing-child poster may become unavailable if a case has been resolved or removed, though that alone does not confirm what happened. No attached case-resolution data states Alive or Deceased, and the online sources reviewed here do not provide a confirmed resolution for the January South Holland listing.
Millie’s case, as reflected online, is therefore a compassionate but incomplete public record of a missing 16-year-old girl in the south suburbs of Chicago, first associated with South Holland in January 2026 and later appearing in a separate Matteson missing-child notice in March 2026. The publicly available details do not explain why the listings differ, whether the January notice was resolved before the later March notice, or what circumstances placed Millie at risk. What is clear is that her name was circulated through missing-child systems, police contact information was provided for tips, and the case depended on public awareness. In overview, Millie Moore was a 16-year-old Illinois girl publicly listed as missing from South Holland on January 21, 2026, with later online records showing a March 24, 2026 missing-child notice from Matteson; the available sources give only limited facts, and no confirmed final outcome is stated in the reviewed online information.
