Georgia's top court has ruled in favor of a former Atlanta police officer who sought immunity after being charged with murder in a shooting of a 19-year-old who was killed while the officer was investigating a report of a vehicle break-in.

The state Supreme Court on Monday upheld by a 6-1 decision a lower court ruling in favor of former officer Raymond Bunn, who claimed he was acting in self-defense when he shot 19-year-old Corey Ward in a parking lot in 2002.

Bunn contended that Ward was driving the SUV straight at him when Bunn shot at the window, hitting Ward twice in the left side of his head.

Prosecutors said Bunn was not directly in front of the vehicle, which belonged to Ward's mother, when he fired.

The Supreme Court majority ruled that the preponderance of evidence favored Bunn's story, despite conflicting evidence.
