‘I was there — I know he killed himself. But I mean (the police) have to investigate,’ Ms Crossman told News Corp this week.

‘I’m dealing with post-traumatic stress because I was the one that found him.’

Detectives arrived on the farm in three cars Saturday morning, with Ms Crossman taken to Tamworth Police station, 100km away.

Her ex-husband Colin Crossman, who is believed to have been one of the first paramedics on the scene following Mr Dunbar’s death, arrived shortly after.

Ms Crossman previously claimed Mr Dunbar had been upset about a limp from a leg infection and had been ‘depressed’ at not being able to run the farm.

Mr Dunbar was found dead at the homestead on August 2 after police and ambulance officers were called to the scene.

‘A 42-year-old woman is assisting police at Tamworth police station,’ a NSW Police spokeswoman told AAP on Saturday.
