Droopystop,
The article said the Gyrocopter was taxing, so I would assume the Hunt fellow must have approached it in order to be hit by it.
Maybe he ran in to try and stop the machine from taxing and got thumped by the blades, that would not be the pilots fault. A pedestrian should not be on the runway/taxiway.
Anyway I'm sure we will hear all about it when the Cops investigate this properly
