We are occasionally asked if we have police or sheriff’s inventory checklists of property seized. I suppose some libraries somewhere have printed checklists, but for the most part the general research rule is:
Each jurisdiction has its own procedure and you usually need to look in the code (the city code, county code, state police regulations, etc.). It is still important to look at the ORS and the OAR, just in case, and some local codes will refer back to these statewide codes.
For example, in the Washington County (Oregon) Code index (which is online), you find:
Inventory, impounded vehicle, person in police custody
Purpose of provisions 9.12.010
Impounded vehicle 9.12.030
Person in police custody 9.12.040
