Wyo. Stat. § 1-17-313: Alias execution.

When goods and chattels levied upon by execution cannot be sold for want of bidders or want of time, the officer who makes the return shall annex to the execution a true inventory of the goods and chattels remaining unsold. The plaintiff in execution may have another execution issued, directing the sale of the property levied upon, but the goods and chattels shall not be sold unless the time and place of sale is advertised as directed in W.S. 1-17-312.
