Property and court records tie Mark to Jeffrey Epstein

Jeffrey Epstein's younger brother, Mark, has long claimed he "wasn't a partner" in—or even aware of—Jeffrey's activities, yet court evidence and real-estate documents draw a continuous line between the two men from the early 1990s through the 2025 Jes Staley hearings.123

301 E 66th St., Jes Staley's testimony about sex in "Mr Epstein's brother's apartment," offers the clearest recent example: it is Mark's building, bought on Jeffrey's tip, managed by Mark's Ossa Properties, and repeatedly listed in trafficking suits as a hub for under-age models.124

  Professional Background

Mark Epstein, a Cooper Union graduate nicknamed "Puggy," pivoted from silk-screen T-shirts to real-estate deals in the early 1990s.6 With a loan from Leslie Wexner's circle, he acquired most of 301 E 66th St.—a 200-unit tower fifteen minutes from Jeffrey's mansion.4 Corporate filings place him as president of Ossa Properties and, at various times, an executive of Jeffrey's own J. Epstein & Co.3 He also chaired Cooper Union (2009-2015) and sits on the Humpty Dumpty Institute board, lending six-figure sums to the UN-adjacent charity.6

  Assessment

Every independent datapoint—real-estate ownership, shared staff, financial pledges, and sworn testimony—places Mark inside Jeffrey's operational orbit. His building supplied housing to victims and employees, his bail pledge surfaced after Jeffrey's arrest, his own deposition shows detailed knowledge of flight manifests. Staley's 2025 acknowledgment in open court further erodes the fiction of distance. Collectively, the pattern shows continuity of interests rather than separation.
