Some Hattiesburg residents woke up Monday morning to writing on the walls.
Authorities say graffiti was spread throughout downtown. The words "Wake Up Hattiesburg" were spray painted on buildings including the Veteran's Museum, City Hall, and attorney Bobby Dukes' office.
City officials say there were no vulgar language or pictures but graffiti of any kind is a serious crime.
"We are going to investigate it to the fullest extent," says city spokesman John Brown.
