MONROE COUNTY, Fla. – Human remains recovered in the Florida Keys in the aftermath of Hurricane Irma have been positively identified nearly eight years later, thanks to advances in forensic science and genetic genealogy.
The Florida Department of Law Enforcement confirmed the remains belong to James Donald Schlake, 77, of Key Largo. The identification was made through advanced genetic genealogy conducted by FDLE Forensic Services in partnership with Othram Inc., a private DNA lab specializing in complex and cold-case identifications.
FDLE secured funding for the testing through the State Forensic Investigative Genetic Genealogy Grant Fund on behalf of the Monroe County Sheriff’s Office and the Monroe County Medical Examiner.
“FDLE’s Key West Field Office and Forensic Services turned over every stone to identify Mr. Schlake,” said FDLE Commissioner Mark Glass. “Our statewide forensic resources and strong partnerships are critical to supporting Florida’s communities and law enforcement agencies. This collaboration helped bring long-awaited answers to Mr. Schlake’s loved ones and to the Florida Keys community.”
Kristen Mittelman, Chief Development Officer for Othram, emphasized the importance of evolving technology. “It doesn’t matter how old a case is. If there is DNA, today’s technology can still bring answers to families. This case shows just how powerful these tools have become.”
The remains were discovered on September 14, 2017, in a debris pile in Big Pine Key during post-storm search-and-rescue operations following Hurricane Irma. Due to the advanced state of decomposition, investigators were unable to determine the man’s identity at the time. An autopsy later determined Schlake died by drowning, and his death was ruled accidental.
Initial DNA analysis conducted in December 2023 did not produce investigative leads. In June 2025, the case was revisited and DNA was submitted to Othram for advanced sequencing and genealogical research. By December 2025, potential genetic relatives were identified, allowing investigators to confirm Schlake’s identity and notify his next of kin.
FDLE says the case highlights how modern forensic technology continues to bring resolution to long-unsolved cases and closure to families, even years after tragedy strikes.
