The young man had brutally murdered his transgender Indonesian wife, 27-year-old Mayang Prasetyo, hours earlier.
He dismembered her body and cooked it in a broth, before the pot spilt over causing electricity in his Brisbane apartment to cut out.
In a chilling phone call – heard on the first day of an inquest into Ms Prasetyo’s death – workman Brad Coyne was told by Volke to, “mind the smell.”
Neighbours described a stench of “rotting meat” coming from the apartment.
In the shocking call, made while his wife sat dismembered in the apartment, Volke told the repairman: “G’day, is this a 24-hour electrician?
“Yeah I got a bit of a problem. Um, I was cooking on my stove, it’s an electric stove and the stock pot boiled over, dripped down and got into the oven and basically made this big bang and then all the power turned off.
“Does it sound like something you’d be able to fix today?”
After Coyne visited the apartment he raised the alarm, telling police he feared something was very wrong.
When officers turned up to the home of Volke, he asked if he could first secure his dogs, locking the apartment front door as he did.
Volke, who like Ms Prasetyo was a sex worker, as well as a professional chef, then killed himself.
He slashed his own throat before stumbling out of the flat in a pool of blood and killing himself in a nearby industrial bin.
Senior Constable Bryan Reid said: “(There) was a bad smell, it was something I hadn’t smelt before and can’t really describe.”
By the time officers got into the apartment they described a scene of horror that took four days to clean.
Ms Prasetyo’s body was found in an overflowing pot that had what appeared to be feet cooking in a pot.
Rubber gloves, bleach, a “squelching” carpet, a vomit-inducing smell were also described next to the “massive” cooking pot on the stove.
The professional sex worker had been working to send money back to her sisters in Indonesia to pay for their education.
Ms Prasetyo was finally laid to rest in Bandar Lampung, after being repatriated from Australia.
Her mother Nining Sukarni said: “Everyone has been very helpful.
“Friends, neighbours, even people from the related government offices. Many of them came to her funeral.”
