If the identity of the last registered owner cannot be determined, or if the registration contains no address for the owner, or if it is impossible to determine with reasonable certainty the identity and addresses of all lienholders, notice by one publication in one newspaper of general circulation in the area where the vehicle was abandoned shall be sufficient to meet all requirements of notice under § 99.03. The published notice may contain multiple listings of abandoned vehicles and personal property but shall be published within the same time requirements and contain the same information as prescribed for mailed notice in § 99.03.
