The father of Denyer’s final victim, 17-year-old Natalie Russell, said he was “relieved” to hear the news.
“This is the best news we have had in 30-odd years,” he said.
“It’s a relief too. We were getting to the point where we thought it was a 50-50 chance that he might get parole.”
Denyer was sentenced to life in prison without parole but the term was later reduced to a non-parole period of 30 years on appeal.
Denyer murdered Natalie, Elizabeth Stevens and Deborah Fream in the Frankston area.
Stevens, 18, was murdered by Denyer after she got off a bus on her way home from the library on June 11.
On July 8, Seaford mother Fream, 22, was killed when she was ambushed by Denyer in her car.
A fortnight later, Natalie, 17, was murdered as she walked home from school.
Victorian MP David Limbrick, who was 19 when his then-girlfriend Natalie was murdered, said it was the result everyone was hoping for.
“We have been dreading this for 30 years,” he said.
“This has been a traumatic process for all the family and friends, and everyone in Frankston.”
Former homicide detective Charlie Bezzina believes there has been little remorse from Denyer over the decades.
“He hasn’t changed. That’s how he is programmed,” he said.
“When we interviewed him, he said he had the urge to kill when he was 15. He will always kill.
“He’s cold, callous and calculated.”
