Shock continues to ripple through Chattanooga, Tenn., as residents try to cope with Thursday's attack. Rabbit Zielke of WUTC reports on the community's reaction.

Two shooting incidents at Chattanooga military facilities killed four Marines, injured three other military personnel and injured one police officer.  The alleged gunman, 24-year-old Mohammod Youssuf Abdulazeez, also died.  Officials are not yet revealing whether police or military personnel killed Abulazeez or whether he committed suicide.

Blood Assurance has been providing a safe blood supply in Chattanooga and 47 other counties since 1973. Prior to that time, people in need of blood had to rely on friends and relatives. In addition to ensuring a plentiful supply of whole blood, Blood Assurance also distributes plasma and blood platelets, primarily to cancer patients. It was the parents of a cancer patient who established the Blood Assurance Foundation. The foundation gives scholarships to local high school seniors every year.
