LOGAN COUNTY, Okla. (KFOR) – Officials are not releasing many details but say that they hope to have answers to several missing persons cases.

The Oklahoma State Bureau of Investigation has been asked to assist in a joint investigation involving several missing persons cases in Logan County, Oklahoma County, and Pottawatomie County.

Authorities with the OSBI say that remains have been recovered during the course of the investigation.

The Office of the Chief Medical Examiner’s confirmed KFOR that “non-intact human remains were recovered” from the sites in rural Logan County and near Lincoln.

“Preliminary anthropology analysis indicates that there may be 3 separate persons from these sites,” said the office. 

The state’s chief medical examiner, Dr. Eric Pfeifer denied our interview request.

However, he is quoted in the Oklahoman saying, “They were associated with burned wood and other material… We’ve got our work cut out for us.”

The Oklahoman reported that Dr. Pfeifer confirmed that “at least nine disappearances are associated with the investigation” and said, “the list keeps growing.”

However, the medical examiner’s office said they could not confirm that number with KFOR. 

Identification of the remains will be determined by the Oklahoma State Medical Examiner’s Office. The medical examiner will also determine the cause and manner of death.

So far, no other information is being released at this time.
