Biography
Mark Epstein, Jeffrey Epstein's younger brother, grew up with Jeffrey in a middle-class household in Coney Island, Brooklyn. While his brother pursued a path through finance and eventually amassed a fortune estimated at over $500 million, Mark built a career in New York City real estate, owning and managing apartment buildings.
The brothers maintained a relationship throughout their lives. Mark Epstein's name appeared in various Epstein-related property records, and he was connected to some of his brother's real estate holdings. Public records showed overlapping business interests, though the extent of Mark's involvement in or knowledge of Jeffrey's criminal activities has not been established in any legal proceeding.
After Jeffrey Epstein's death at the Metropolitan Correctional Center on August 10, 2019, Mark took a prominent public role in questioning the official findings. He hired Dr. Michael Baden, one of the country's most well-known forensic pathologists and former New York City Chief Medical Examiner, to observe the autopsy conducted by the Office of Chief Medical Examiner. Dr. Baden subsequently stated publicly that certain injuries — particularly fractures to the hyoid bone and thyroid cartilage — were more consistent with homicidal strangulation than suicidal hanging, contradicting the official ruling by Chief Medical Examiner Dr. Barbara Sampson.
Mark Epstein has given limited public interviews, including a notable appearance on Fox News where he expressed skepticism about the suicide ruling and called for a more thorough investigation. He assisted in managing aspects of his brother's estate, which was the subject of multiple lawsuits from victims. The estate established a voluntary victims' compensation fund that ultimately paid over $121 million to more than 135 claimants.
