Overview

• Susan Mann was 15 when she vanished from her Hollis, Queens home on May 17, 1980; her decomposed body was found Nov. 4, 1982 in a dumpster behind Cantor Glass Works in Freeport.
• Detectives exhumed the previously unidentified remains and, with investigative genetic genealogy — including assistance cited from the FBI program — confirmed Mann’s identity.
• Nassau County police say evidence suggests the body was likely buried shortly after 1980 and later moved to the Freeport dumpster in 1982, and the homicide investigation remains active.
• Investigators released images and details of items recovered with the remains, including a blue-and-yellow striped jacket and two 14‑karat gold pendants — an opal and a heart with the initial “K.”
• Crime Stoppers is offering up to $25,000 for information leading to an arrest, and investigators are seeking tips from anyone with knowledge of Mann or activity in the Freeport area between 1980 and 1982.
