Summary based on the NamUs case record (MP22171) and 4 other sources
Maria Mercy was a 13‑year‑old girl who vanished from Miami, Florida, with her last confirmed sighting on **July 8, 2000**. Law enforcement records, including those aggregated through NamUs, list her disappearance date reliably as July 8, 2000, and provide key physical descriptors such as her height of **5′0″ ** and weight around **130 lb**.

At the time of her disappearance, Maria was described as a **White female** with **blonde or strawberry‑blonde hair** that was **long and curly**, though eye color remains listed as unknown. Additional identifying details include **possible gold upper teeth** and a **non‑descript tattoo on her right arm**, noted in Florida’s official missing‑person database.

Very little information is available about the circumstances leading up to her disappearance. Publicly accessible case details do not elaborate on what she was doing immediately before July 8, 2000, nor provide information on whether she was last seen at school, home, or elsewhere. There is no indication in available summaries that she was considered a runaway; instead, she remains listed among unresolved missing persons in Miami‑Dade County.

Maria’s case has remained cold and largely stagnant over the past two decades. Although she is included in major missing‑persons repositories—including NamUs, with case number **MP22171**—and Florida’s Missing and Endangered Persons Clearinghouse, no public updates, identifications, or confirmations of foul play have been reported. The last recorded update to the NamUs file dates to April 2021, and there have been no significant developments in news or law enforcement bulletins since, according to publicly accessible listings.

According to online community posts on forums like Websleuths and Crimewatchers, Maria’s disappearance continues to spark concern among missing‑persons watchers. For example, one Websleuths thread clearly reiterates the official information:

> “Per law enforcement – the missing person was last seen on July 8, 2000”
> and describes her as “blond/strawberry; long and curly” with her height and weight as documented. Despite the passage of time, these forum threads generally repeat the same limited details and express frustration over the absence of new facts or leads.


Her disappearance remains unexplained, with no confirmed sightings or clues since that date. Authorities continue to list the case, and community interest persists, but official updates have been scarce and the case remains unsolved to date.
