On November 26, Spokane Valley Deputies responded to a call of an intoxicated male choking his juvenile brother-in-law.

39-year-old Dmitry Ivanchenko was arrested for Assault in the 2nd Degree and for Obstructing Law Enforcement.

Deputies were called to the home in the 8500 block of East Alki in Spokane Valley on Saturday.

Deputies contacted the victim, his sister (suspect’s wife) and her young child who locked themselves in a vehicle parked in the driveway after fleeing from the suspect to call 911.

Deputies were told Ivanchenko began choking the victim during an argument. The victim stated his airway was obstructed and he felt he would lose consciousness and feared for his life. Red marks consistent with strangulation were observed on the victim’s throat and the suspect’s wife confirmed the victim’s account of the assault.

Deputies gave several loud unanswered verbal commands from the front door of the residence advising Ivanchenko he was under arrest and to surrender.

As additional units arrived, including a K9, additional announcements were made advising Ivanchenko a K9 would be used to locate him if he did not surrender but they went unanswered.

The K9 was eventually deployed and quickly began barking at a utility trailer full of boxes and garbage bags.

Ivanchenko continued to resist arrest and began striking the K9 and pulling on the area around the K9’s eye as he continued to fight inside the rocking and unstable trailer.

While attempting to gain compliance and take Ivanchenko into custody, deputies used force including strikes using a flashlight and a straight stick baton but Ivanchenko continued to fight.

Fearing Ivanchenko was attempting to access a weapon and that the deputy’s life, or the lives of the other deputies were in danger, a deputy drove the end of his straight stick baton into the suspect, making contact with Ivanchenko’s head.

Deputies were able to gain control and place Ivanchenko in custody. Ivanchenko was searched and found not to be in possession of a weapon. Medics were called to the scene to provide medical treatment for injuries to Ivanchenko’s leg and head.


Ivanchenko was transported to a local hospital for medical treatment. Initially it was believed he would be treated and released but has been held for observation since the incident. Ivanchenko will be transported and booked into the Spokane County Jail following his expected released from the hospital later this evening.

None of the deputies or the K9 were injured during the incident.

Due to the level of force used Major Crimes Detectives were called to the scene to investigate. The Spokane Investigative Regional Response team has been called to investigate.
