(Portland, OR)  --  A wanted man is dead from a self-inflicted gunshot wound following an hours-long police standoff at a home in Keizer.  Police say the 65-year-old man was armed with a gun when he entered an apartment near River Road and Sandy Drive last night and refused to come out.  Police finally obtained a search warrant early this morning and entered the apartment to find the man dead.  Police say he had two felony caution warrants out for his arrest and had been convicted of murder in the past.
