The Columbia County Sheriff’s Office is investigating the drug sale of drugs that resulted in a woman overdosing near Gooding and Schaefer roads in northeastern Columbia County.

Shortly after 3 p.m. on Sept. 12, sheriff’s deputies responded to a call about an unconscious woman in the roadway near the intersection of Gooding Road and Schaefer Road. The woman showed signs of drugs, Sheriff Stu Smith said in a news release.

Deputies immediately began to assist the woman, who was transported to Essentia Health in Newberg.

The on-call nursing staff administered the key drug anesthetics that were used to treat the woman, a female adult, but it had yet to be determined which drug she was taking.

The other drugs deputies had been able to treat the woman, the news release stated, were later determined to be heroin, methadone and Xanax.

“The accident occurred at the intersection of Schaefer Road and Gooding Road due to cars being forced in front of each other due to traffic signal problems,” the news release stated. “Due to the same traffic signals, sheriff’s deputies were called to assist with traffic control, and subsequent to this incident, officers went to make arrests in the area.”

As of 5 p.m. on Sept. 13, it was not clear how many people were arrested or how many drugs were taken into custody. Smith could not be reached for comment on the status of the investigation.
