Murders
Denyer stalked and murdered three women in and around the Melbourne suburb of Frankston during a seven week period in 1993. Denyer was 21 at the time of his crimes. During a police interview Denyer said the motivation for his crimes was a hatred of women in general.

Victims
The first victim was 18 year old Elizabeth Stevens. She had just alighted from a bus to Langwarrin when she was dragged to nearby Lloyd Park. Her throat was slashed and a criss-cross pattern was carved into her chest.
A month later, the second victim, Deborah Fream, was abducted in the early evening. She had left her car unlocked to run into a store to buy milk. Denyer climbed into the back seat, and hijacked the car after Fream drove from the store. She was taken to Taylor's Road and, like Stevens, her throat was slashed savagely. She had left her 12 day old baby at home with a friend when she left to buy the milk.
Rosza Toth was attacked by Denyer while walking home from Seaford railway station on the evening of Deborah Fream's abduction. Toth was dragged towards the toilet block. She managed to break free of Denyer's grasp and notified police.
The third and final victim, 17 year old Natalie Russell, was attacked while walking home early from school. She had taken a short cut home along a bicycle track through a park. She was dragged from the path through a large hole in a wire fence, but put up a huge fight. This made Denyer angry, and he slashed at her head and neck. Russell's death was the most brutal.
Connections with the 1990 disappearance of Sarah MacDiarmid from nearby Kananook railway station were made. MacDiarmid's body has never been found. The only evidence suggesting a crime was a pool of blood next to her car, parked at the station. Denyer denied involvement in MacDiarmid's disappearance.
Similar connections to the murder of Michelle Brown have also been discussed. She was found naked, and her body was too decomposed to examine the injuries.
Sex reassignment requests
Denyer began dressing as a female while imprisoned.
Whilst imprisoned, Denyer requested to be allowed to purchase and wear women's cosmetics, which was denied.
Denyer also filed freedom of information requests to learn of the Victorian government's policy on gender reassignment surgery for prisoners and has sought evaluation to determine his suitability for such surgery, which was also rejected by medical specialists
