The witness spent some time with the suspect and said Laurean appeared to be traveling alone, the sheriff said. He described the sighting as "transient" in nature and expressed hope that Laurean would soon be in custody.
Brown urged members of the public not to try to detain Laurean if they spot him.
Based on the evidence of the crime, Laurean "could be a dangerous and violent person if he was put in a corner," the sheriff said.
The Shreveport, Louisiana Times reports that U.S. Marshals contacted their local police after they got word Laurean may have gotten off a Greyhound bus in Shreveport.
