(Portland, OR) -- A 36-year-old man is facing a nine-count indictment in Multnomah County following his arrest in an on-going investigation into a multi-state drug trafficking ring. Police arrested Kao Sae Chao in February. Court documents say a search warrant was served at a home in Southeast Portland, where officers seized nearly 17-thousand dollars and heroin. Sheriff's deputies seized guns and drugs in a search of his car. In addition to the Portland area, investigators learned the ring was operating in Colorado and Indiana.
