As the search for Michael Paul Brown stretched into its fifth day, Montana Gov. Greg Gianforte signed an executive order freeing up more resources for local law enforcement.

The search for a former U.S. soldier suspected of killing four people at a Montana bar has stretched into a fourth day with no capture.
