(CNN) A "disgruntled employee" who shot and killed a person and wounded another at a Charleston, South Carolina, restaurant was shot and critically wounded, Mayor John Tecklenburg told reporters Thursday.
Several hostages were safely released.
"This is not act of terrorism," Tecklenburg said while the situation was going on. "This is not a hate crime. It's a disgruntled employee who has come on the scene of his employment."
