Marshall Lee Dino was listed in NamUs as a missing person under case number MP159105, with the case page identifying him as missing from Mulberry, Florida, and recording his date of last contact as May 31, 2026. The case was created in NamUs on June 3, 2026, only days after he was last known to have had contact, placing the public record of his disappearance very close to the time he went missing. The available public details are limited, but they establish the core facts of the case: Marshall was 14 years old, from Polk County, Florida, and his disappearance was tied to the Mulberry area.
Project DoeMain's missing persons listing also identifies Marshall Dino as a 14-year-old male missing from Mulberry, Florida, with a listed missing date of May 31, 2026. That entry identifies the source as NamUs and shows the case was last updated by the source on June 3, 2026, reinforcing that the public information currently available comes from the official national missing-persons database rather than from extensive local reporting.
The attached public case data identifies Marshall as Marshall Lee Dino, a White/Caucasian male, 14 years old at the time he went missing and still 14 at the time of the listing. He is described as 5 feet 9 inches tall and about 130 pounds, with brown hair and hazel eyes. The public case record does not list a nickname, clothing description, known transportation, distinctive physical features, or detailed circumstances beyond the statement that he was last seen on May 31, 2026, in Mulberry, Florida. The absence of those details does not lessen the urgency of the case; it simply means the publicly released record is sparse.
The investigating agency listed for the case is the Polk County Sheriff's Office, which serves the county where Mulberry is located. Florida's Missing Endangered Persons Information Clearinghouse describes itself as the state's central repository for information on missing endangered persons and says it assists law enforcement and the public in finding missing persons through analytical services, public engagement, and alert coordination. For families and communities facing a disappearance, those systems matter because even a brief public case file can help place a missing child's name, location, and identifying information into searchable state and national channels.
NamUs itself is described by the National Institute of Justice as a central database and support program used by law enforcement, medical examiners, coroners, investigators, and families to help resolve missing, unidentified, and unclaimed persons cases. NIJ notes that NamUs also provides tools and support services, and that public participation can be important because families, volunteers, advocates, and members of the public may search publicly visible information and help keep attention on missing-person cases.
There is no public case-resolution status in the provided data showing Marshall Lee Dino as found alive or deceased, and the available online sources reviewed do not provide additional verified circumstances explaining why he disappeared or where he may have gone after he was last seen. What is publicly known is that a 14-year-old boy named Marshall Lee Dino was reported missing from Mulberry, Florida, after last contact on May 31, 2026; his case was entered into NamUs as MP159105 shortly afterward; the Polk County Sheriff's Office is identified as the investigating agency; and the public record remains a concise but important appeal for recognition, awareness, and information in the case.
