Police say a homeowner shot and killed a man who crawled through the doggie door of a house in north Spokane.

Spokeswoman Monique Cotton says the intruder was armed with a large knife and had been threatening residents in a domestic dispute.

The man had crawled through the doggie door about 7 p.m. Wednesday and was coming at the homeowner when he fired a handgun. Officers attempted CPR but the intruder died at the scene. An autopsy on the Spokane man is being conducted Thursday.

Six people in the home at the time cooperated with investigators. Police searched the single-family residence, and no one was arrested.

Cotton says it's unlikely anyone will be charged, although the decision is up to prosecutors. She said the homeowner was protecting his property.
