A man who was holding a knife to a teenage hostage's throat was shot and killed by a Fayette County sheriff's deputy early Saturday when he refused to drop the knife, authorities said.
Fayette sheriff's spokesman Brent Rowan said deputies responding to a 3:35 a.m. call about a fight in progress at a home on Buckeye Road "encountered a 22-year-old male suspect holding a 17-year-old victim hostage with a knife to the victim's throat."
Rowan said the suspect, whose name has not been released, refused to drop the knife.
After ordering the man multiple times to drop the knife, a deputy fired a single shot, striking and killing the suspect, Rowan said.
The deputy's name has not been released.
The GBI was called in to investigate the incident, Rowan said.

Will wait for more info - but it makes one feel good that we have such quality individuals who are so well trained to perform this act. Hope the hostage is OK.
