Homicide Investigation Initiated After Amity Man Taken Into Custody
Yesterday, at about 12:30 p.m., Yamhill County Sheriff’s deputies arrived at 504 S. Trade Street in the City of Amity to contact Alex Ernest Tombleson, 31 years of age. Tombleson was in a mental health crisis. In addition, there was probable cause to arrest him on misdemeanor charges related to a domestic harassment incident that occurred several hours earlier.
Due to Tombleson’s recent demeanor, deputies arranged for a Crisis Intervention Deputy, a Yamhill County Mental Health Community Outreach Specialist, and Tombleson’s probation officer to accompany them to the residence. The hope was these individuals could assist with taking Tombleson into custody without incident and get him engaged in treatment.
After deputies arrived, they discovered Tombleson had barricaded the doors to his residence. Attempts to negotiate with him were unsuccessful by all parties, including his family, and he made threats of death toward deputies. At this time, deputies chose to leave the scene to deescalate the situation and allow Tombleson to calm down.
At about 5:00 p.m., deputies and Community Outreach returned to Amity to attempt to contact Tombleson. Tombleson was still engaged in crisis and the residence was still barricaded. All attempts at establishing productive communication with him failed. Deputies again chose to disengage and allow Tombleson to calm.
As deputies prepared to leave, Alex Tombleson’s father, Ross Tombleson, 69 years of age, entered the apartment through an upstairs window. Deputies and family members attempted to establish communication with him but were unable to get a response. Additional units were called in to set up containment and the Crisis Intervention Team deputy continued to try and establish communication.
All attempts at establishing contact with Ross Tombleson were unsuccessful, and Alex Tombleson continued to be uncooperative. There was reason to believe that he may have accessed a firearm from inside the residence.
Yamhill County Sheriff’s Office contacted the Oregon State Police who agreed to activate their tactical team to assist with the incident. After approximately 8 hours of negotiation by Yamhill County deputies, community outreach specialists, and OSP SWAT troopers, Alex Tombleson came out of his residence voluntarily, and was taken into custody. Ross Tombleson was located deceased inside the residence. The death is being investigated as a homicide.
Alex Tombleson was lodged in the Yamhill County Correctional Facility for violation of probation and misdemeanor harassment and criminal mischief. He is being held without bail as this homicide investigation continues.
The investigation is being conducted by the Yamhill County Sheriff’s Office Special Investigations Unit with the assistance of the Yamhill County Major Crimes Response Team (MCRT). MCRT is a multi-agency team made up of law enforcement partners within Yamhill County and the Yamhill County District Attorney’s Office.
No further information will be released at this time. The investigation is ongoing and additional details will be released when appropriate.
