A second person has been charged with murder over the death of a New Zealand firefighter in the NSW Hunter Valley in Australia.
The body of Ian Pullen, 43, was found on the side of a road in Glenridding, near Singleton, in September 2018.
Pullen was a helicopter pilot who had arrived in the region to assist with firefighting efforts.
Detectives arrested a 30-year-old woman at a home in Singleton yesterday morning, and she was charged with murder.
Police alleged that after a white ute hit Pullen, the woman and the driver of the vehicle returned to the scene a short time later and struck him in the head with an object.
Joshua Knight, 29, was arrested last week and charged with murder, dangerous driving occasioning death and failing to stop and assist after vehicle impact causing death. He was refused bail in Newcastle Local Court.
The arrests came three weeks after police made a plea for an anonymous caller to come forward.
They asked for the unknown late-night caller to come forward on the second anniversary of the death.
A $350,000 reward was offered last year for information on Mr Pullen's death.
The 30-year-old woman was refused bail and will face Muswellbrook Local Court today.
