Former Jetstar pilot Greg Lynn may yet be forced to answer more uncomfortable questions about the 'suicide' of his ex-wife. 

Lisa Lynn was found dead in October 1999 after consuming a lethal cocktail of booze and sleeping tablets.

It can now be revealed detectives are looking to have the Victorian coroner open a second inquest into the mother-of-two's tragic death. 

On Tuesday, a Supreme Court of Victoria jury acquitted Lynn of the murder of elderly camper Russell Hill, but found him guilty of the murder of Carol Clay. 

Detectives tasked with bringing Lynn down now believe there is enough new evidence in the Lisa Lynn case to warrant a fresh inquest. 

It is understood police are in the process of talking to those who knew Lynn in the hope of learning more about what information he shared about his then wife two decades ago. 

Lynn's unusual personality has long been the subject of speculation amid airline circles, the Herald Sun reported. 

The disgraced former pilot spent five years flying passenger planes for Qatar Airways in the Middle East before joining Jetstar in 2007.

On Wednesday, a police spokesperson told Daily Mail Australia its investigation into Lisa Lynn's death remained ongoing. 

'Detectives from the Missing Persons Squad have conducted a review into the 1999 death of a 34-year-old woman in Mount Macedon,' a statement read. 

'This investigation remains ongoing, and an application has not been made to the Coroner at this time.'

Rumours have swirled within the airline industry for years about a woman who reportedly went missing in the desert while in Qatar at the same time as Lynn.

Her alleged disappearance was spoken of by those who knew Lynn years before he was charged over the murders of the campers, the newspaper reported.

It is a story believed to have piqued the interest of detectives not finished probing the extent of Lynn's criminality.

Lisa Lynn's parents had previously told the coroner about their concerns about the then pilot while he was living with their daughter in Mount Macedon, north-west of Melbourne. 

Lisa was found in the foetal position out the front of the family's home, while the couple's two children, aged one and three, were asleep inside.   

Victorian Coroner Graeme Johnstone said Lisa was believed to have been deeply depressed at the time of her death.

However, the coroner was left with outstanding questions over whether she had intended to take her own life or not. 

Forensic doctors later revealed her blood alcohol content was a whopping 0.2 - more than three times the legal limit to drive a car.

They also found traces of antidepressants in her system.

Lisa's mother, who would travel from Tasmania to help her struggling daughter, provided a disturbing statement to the coroner about Greg Lynn, including accusations of animal cruelty, violence and 'bizarre' behaviour. 

'In addition to not gaining any support from Greg, he would subject her to physical and mental abuse on a regular basis,' she told the coroner.

'These events happened too frequently to remember, specifically but things like losing his temper for no reason and blaming Lisa for anything that went wrong. 

'He then would yell and throw things at her and push her around. I felt very uncomfortable when these events occurred because I was not inclined to interfere and Lisa would plead with me not to interfere.'

 Lisa's mum told the coroner her daughter told her any interference from her would result in further pain and misery at home. 

'Greg's behaviour in general would be described as bizarre. In my opinion, he has a warped mind,' she told the coroner. 

'He has done things in the past like killing animals and a neighbour's pet, refusing to feed the children when he was supposed to be looking after them and on one occasion, he exploded into a fit of uncontrollable rage when we went for dinner at the Macedon Hotel.'

Lisa's mum told the court Lynn verbally attacked a man in the bar after he made the mistake of speaking to Lisa. 

He then flew into a 'rage' at his then wife after leaving the hotel, she told the coroner. 

'The only thing that I would like to add is that as far as I'm concerned, Greg is responsible for my daughter's death by mental torture inflicted by him,' Lisa's mum told the court.

'I know that she was living in absolute fear of Greg. I accept from what (I'm told) regarding the circumstances in which she died that she was alone on the night. 

'Greg was not there however her actions were a culmination of the fear and terror that she lived under.'

The court heard Lisa had kept a detailed journal and diary of her fractured relationship with Lynn. 

Lynn will face court at a future date for a pre-sentencing hearing over Clay's murder.
