“It’s certainly a terrible crime and a very violent crime,” he told 3AW on Thursday morning.
“She was someone who was well known in the greyhound industry. It’s certainly sent shock waves through the Devon Meadows area.”
Those close to Ms Leek have described her as a hard working, much-loved and dedicated greyhound breeder known to raise champion racers.
Greyhound Racing Victoria said she was one of the most respected people in the industry who had been recognised for her success as a breeder, rearer and trainer.
“Karen had an outstanding reputation as a commercial rearer, having raised many champions including Bewildering, Brokenwood, Extreme Magic, Godsend, Moreira and Nolen,” they said in a statement on Wednesday.
Ms Leek also volunteered on panels for the sport and was a committee member of the Greyhound Owners Trainers and Breeders Association, which said it was “deeply saddened” by the news.
Ms Leek had lived on the sprawling property with her 90-year-old mother Viola up until the elderly woman died in March. The pair had lived together at the same Cross Road address they had co-owned for more than two decades.
That has since raised questions about a possible family feud.
While the exact circumstances of her death are still to be determined, police said they were treating it as “suspicious”.
Investigators are appealing for anyone who may have seen activity in recent days at the property – on Cross Road between Stanley and Murray roads – to come forward.
Police are also keen to speak to anyone who may have driven past the property or in the area and has dash-cam footage.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or visit crimestoppers.com.au.
