Police Seized Auctions

How do I find the timing of the police auctions in the state of Oregon?
I'm trying to find a schedule of dates and times police auction (seized, exclusions, etc.), many places tell me they can pay for this information, but there must be a public list and free, as through a agencyt government. Can anyone help?
I went to a police auction last Friday night. It was published in the newspaper local. I bought a washing machine confiscated and an electric clothes dryer in almost new for $ 150.00. Try calling the local police station and ask where and when they will be held. The police want to make money on their items confiscated so they should be willing to tell everyone where they are detained. Good sort of a buyer of Lucky.
