Othram Identifies 2021 Lake Okeechobee Remains as Missing Boston Veteran

Remains recovered along a trail near Lake Okeechobee in June 2021 have been formally identified as William McKinnis, a veteran from Boston, following advanced forensic genetic genealogy work by Othram Inc., authorities announced Jan. 23. The Palm Beach County Sheriff’s Office says investigators collected DNA samples from potential relatives in 2025 and the laboratory confirmation came in September of that year.

The identification closes a long-standing gap in the county’s John Doe files and shifts the investigation from an anonymous remains case to one centered on a missing person with military ties. Palm Beach County Sheriff’s Office officials are now asking anyone who knew McKinnis between 2019 and 2021 to come forward with information about the circumstances of his death. Investigators say new leads from the public could be critical to determining cause and manner.

The case highlights the growing role of private forensic genetic genealogy laboratories in resolving cold cases. Othram’s work paired genealogical DNA analysis with traditional investigative follow-up to move from degraded or limited biological material to a named individual. That pathway has become a key option for law enforcement when conventional identification methods stall, especially in cases where remains are skeletal or decomposition complicates immediate identification.

For the local community and advocates for missing persons, the identification matters on several levels. Family members gain the factual anchor needed to pursue closure and next steps such as notification, funeral arrangements, and access to veterans’ records. Neighbors and frequent visitors to the Lake Okeechobee area receive confirmation that the case is no longer an anonymous recovery but an active investigation tied to a named person. Cold-case sleuths and forensic genealogy practitioners will note another example of how public DNA matches and private lab resources can resolve cases years after a recovery.

Investigators emphasize that identification is only the beginning of the investigative arc. With a name now attached, detectives can reconstruct McKinnis’s last known movements, contacts, and medical or military history. Anyone with details about William McKinnis’s whereabouts, associates, vehicles, or activities between 2019 and 2021 is urged to contact the Palm Beach County Sheriff’s Office to help fill gaps in the timeline and possibly determine the cause of death.

This development underscores both the technological advances available to investigators and the practical importance of community memory. As forensic genealogy continues to unlock identities in cold-case files, timely tips from people who knew missing individuals remain the most direct route from identification to answers.
