At approximately 11:45 p.m. Saturday, Tillamook County 911 received a report of a stabbing outside Koko’s Restaurant.

Two men and a woman were stabbed and two suspects fled into the darkness toward the golf course. A Tillamook County deputy and an OSP trooper searched the golf course and arrested two suspects about an hour afterward.

The other two victims were transported by Tillamook Ambulance to the same hospital. They were identified as Sean Matthew Bennett, 28, from Bay City, and Chelisa “Sissy” Vandecoevering, 26, from Garibaldi. Both received wounds to their bodies.

All three were treated and released.

The two suspects are Juan Emigdio Valencia-Ayala, 21, from Tillamook, and Jacob Zavala Krumenaker, 20, from Garibaldi. Both were lodged in the Tillamook County Correctional Facility on three counts of first-degree assault.

Detectives from TCSO and OSP are continuing the investigation. Tillamook Police Department assisted at the scene. Investigators processed the scene and interviewed witnesses during the night.
