When detectives Florence and Justin left Lynn's home that day, they turned their attention to finding out everything they could about Gregory Lynn. Gregory Stuart Lynn was a 55-year-old commercial airline pilot. Decades earlier, he'd worked for the now-defunct Australian airline Ansett. While he came across as charismatic, some of Lynn's co-workers had found him unsettling.

One described him as a dead-set weirdo with a wicked temper. Lynn had married a woman named Lisa who was a flight attendant and colleague. They built a sprawling family home in Mount Macedon, had two sons, and, inspired by the movie Babe, bought a piglet they named Pig. To outsiders, it seemed idyllic. Behind closed doors, a darker story emerged.

Lisa's family and friends described Gregory Lynn as increasingly controlling and abusive. Lisa's mother would later detail frequent incidents of physical and mental abuse. She said that on one occasion, Lynn had exploded into a fit of uncontrollable rage after another man spoke to Lisa and her mother while they were out for dinner at a pub.

He verbally attacked the man in the bar, then redirected his rage at Lisa after they left. A former neighbour later told 60 Minutes about a punishment meted out by Gregory Lynn when Lisa had drunk too much. Lynn's own unsworn statement corroborated this account. He described wanting to teach Lisa a lesson for her drunkenness.

"'I bound her hands and feet with masking tape and carried her outside into the backyard.' I put her near the back steps and hosed her down with water from a garden hose, and she got extremely cold. I agree this action was quite unusual, but my intentions were for her to never drink to excess like that again. Lisa was left to freeze overnight. The allegations grew more sinister.

After Pig dug up Lynn's prized plants, Lynn allegedly killed the beloved pet with an axe, leaving its head on the doorstep for Lisa to find. Neighbours reported finding their dog strung up on their fence, its throat slit, after Lynn had complained about its barking. In another incident, he allegedly killed a stray pig with a shovel when it wandered onto his property.

The marriage crumbled after Lisa discovered photos confirming Lynn's affair with another flight attendant in his pilot bag. Lisa subsequently sought help through the family court for child maintenance. An interim intervention order was imposed in March 1999 preventing Lynn from assaulting, harassing or threatening Lisa.

He would later plead guilty to breaching this order twice, once by breaking in and stealing the family car, purposely leaving Lisa stranded. Though Lisa documented the abuse in a diary, she feared pressing charges. On Tuesday October 26 1999, she was found dead in their Mount Macedon garden.
