An anti-Donald Trump campaigner has been charged with murdering his Republican neighbour after a series of disputes boiled over into violence.
Clayton Carter allegedly shot George Jennings twice in the head after a row, reportedly the latest in a string of confrontations that had seen the police called dozens of times over several years.
It happened after an argument about a spotlight, US media said, but Mr Carter's lawyer said his client acted in self-defence after being threatened with a knife.
Mr Carter's front garden was filled with anti-Donald Trump signs, ABC 6 reported, while Mr Jennings was a member of the local Republican Party committee. Both were 51.
But it was not claimed their political views were a cause of the killing.
One neighbour said of Mr Carter: "We steered clear of him. We were frightened of him because he's so unpredictable."
Police said he had argued with other neighbours and had previously threatened Mr Jennings with a gun.
"My client says he was justified in doing so because he was under attack by a knife wielding assailant," lawyer Terrence Marlowe told ABC 6.
