DCSO sergeant on leave resigns amid ongoing investigation

A Deschutes County Sheriff’s Office sergeant on leave for alleged policy violations has resigned.

Sgt. Deke Demars submitted his resignation on April 1st and is no longer an employee with the DCSO, according to a statement from the agency.

In February 2020, Demars was placed on leave while an outside agency conducted an investigation.

Deschutes County District Attorney John Hummel said at the time it was not something his office would investigate because it was a “purely personnel matter.”

But the personnel matter turned into a potential criminal investigation after an independent review by Redmond Police.

In February of this year, that investigation found probable cause for sodomy charges against Demars.

In a 10-page, highly-redacted report, Redmond Police Investigations Lt. Aaron Wells concluded “there is probable cause the crime of Sodomy has been committed” by Demars with a woman he was in a relationship with.

“[Redacted] had a clear recollection of the sexual encounter. She told friends, went to the extent of seeing a doctor and was clear communicating to Demars and othear [sic] she did not want to have anal sex,” Wells said in the report. “[Redacted] has decided she does not want to be a victim at this point and as such I am requesting this report be forwarded to the Deschutes County CDDA Steve Gunnels for information.”

The report, obtained by Central Oregon Daily News from Hummel’s office, details information from a recording of a Deschutes County Sheriff’s Deputy and his wife.

Wells said through the recording and subsequent interviews he learned Demars was allegedly  “physical” with a woman, is “highly controlling by words and uses verbal abuse” and threatened to have the woman’s children taken away.

The report goes into graphic detail about alleged unwanted and rough sexual encounters.

The report also said the woman “believed Demars would do her harm if she was the reason he lost his job.”

Sheriff Shane Nelson declined to comment on the investigation.

“When it comes to administrative investigations, you always want to make sure you go where the evidence and the facts lead you,” Nelson said. “Their length of time has to do with how much evidence is uncovered and the number of witnesses you have to speak to. That really dictates how long they can take.”

Monday’s announcement comes two days after the agency announced Capt. Deron McMaster was placed on paid administrative leave pending the outcome of an investigation into alleged policy violations.

No other details were given in that case.
