Maximillian Olegovich Soloviev, born May 21, 2002, was four years old when he disappeared from Belmont, Massachusetts on June 8, 2006. According to official missing‑persons listings, at the time of his disappearance he stood approximately 3 ft 8 inches tall, weighed about 40 lbs, had sandy blonde hair and blue eyes, and was Caucasian.
Remarkably, Maximillian primarily speaks Russian and may go by nicknames such as “Max,” “Maksusha,” or “Maximka.”
He may also use variant spellings or alternate last names—including Sobolev, Solovyev, or Tyukhtyaev—when traveling or in documents.
Law enforcement and missing‑person agencies—such as NCMEC and NamUs —classify his disappearance as a family abduction, indicating he was likely taken by his non‑custodial mother, identified as Anna Soloviev in some advocacy sources, though photographs or identifying details for her are scarce.
Immediately following his disappearance, investigators have maintained that Maximillian and his mother may have left the United States, potentially traveling to Russia or to islands in the Caribbean, though no confirmed sightings or contacts have been verified in the years since.
Over the past two decades, very little additional information has emerged. No verified sightings of Maximillian or Anna have been publicized; the case remains officially open and unresolved. Publicly available databases and cold‑case advocacy websites focus on sharing basic information and encouraging tips, but details are limited and seem not to have changed since the case was first documented by Charley Project .
Authorities originally listed the investigating agency as the Sharon Police Department and public listings note contact information for NCMEC and NamUs. The case remains listed with NamUs as MP20522 and associated with NCMEC poster number 1061765.
In summary: Maximillian Soloviev vanished from Belmont on June 8, 2006, in a suspected parental abduction by his non‑custodial mother. At disappearance, he was a 4‑year‑old Russian‑speaking Caucasian boy, nicknamed “Max,” around 3'8" tall and 40 lbs, sandy hair and blue eyes. He may have traveled outside the U.S., possibly to Russia or the Caribbean under alternate names. Despite being listed in national databases and discussed on advocacy sites, the case remains unsolved and extremely limited in publicly available updates.Last Seen: Jun 8, 2006
