While the possibility of foul play was a significant concern, authorities say they have found no evidence or probable cause to suspect criminal activity linked to Walker's death. "Though foul play cannot be ruled out completely, there is no evidence or probable cause to believe that a crime was committed," Sheriff Songer added, marking an end to the lengthy investigation.

Songer stated that he believes arresting someone for killing a wolf when it is attacking or killing livestock to be “a violation of the individual’s Constitutional rights.”
