(Milwaukie, OR)  --  Milwaukie police say a K-9 named Kilo was instrumental in nabbing a burglary suspect who was armed with a knife at a Milwaukie insurance office.  Authorities say officers arrived at a State Farm office on Southeast Rusk Road early yesterday morning, and found that the suspect had broken in and was trying to hide in the building.  Police sent in Kilo, who bit the suspect on the arm even though the burglar began violently swinging a samurai-style knife.  Police say 37-year-old Timothy Allen Nelson was already on parole for burglary.
