The mother of a man believed to have killed and dismembered his transgender girlfriend in Brisbane before taking his own life said she had no indication anything was wrong.

Authorities are still trying to contact the victim's next of kin in Indonesia with investigators returning to the scene today as they try to piece together events leading up to the crime.

Marcus Volke ran from police when they arrived at his apartment in the upmarket suburb of Teneriffe on Saturday night to investigate reports of a foul smell.

Volke fled through a rear glass door and leapt over a balcony, leaving a smear of blood on a fence.

The 27-year-old's body was later found in an industrial bin, where it is believed he took his own life.

Police would not confirm reports that Volke had been cooking a part of his girlfriend on a stove top when they arrived at the scene.

The man's mother, Dorothy Volke, told the ABC she had not had any indication anything was wrong with her chef son.

"I'm not sure what he was doing - last we knew he was working on boats," she said.

She said she did not know what company he was working for.

"I don't know, he jumped around," she said.

It is believed Volke met his girlfriend Mayang Prasetyo while working on international cruise ships.

Ms Volke said she had not met her son's girlfriend, whom the ABC understands was Indonesian.

Volke was originally from the regional Victorian city of Ballarat, where his funeral will be held.

Police on Monday helped a commercial waste disposal worker remove a bin labelled "toxic" from the apartment block.

Investigators are hoping security cameras near the apartment complex may help shed light on the events of Saturday night.

Just a normal couple, neighbour says

Neighbours alerted the building's manager of the stench on the ground floor on Saturday.

Courtney Reichart first noticed the smell on Wednesday when she returned home from work.

She said it got worse each day and still remains.

"On Saturday when I came out for a walk, it made your eyes water, it made you want to be sick," she said.

"The smell it was like as if somebody had put out some dog food or red meat and left it out for a few days.

"It makes you feel sick that that poor girl sat there for however many days and we've been walking past, living our lives and thinking 'hmmm what's that smell', but you don't put two and two together.

"You don't think that a bad smell equals a murder."

The apartment complex only opened about two months ago, during which time Ms Reichart had met the couple a number of times.

She said she had never heard arguments, and the couple owned dogs.

"Just a normal couple," she said, adding that the girlfriend was "gorgeous".

"They seemed quite friendly."

Volke critical of violence against women

Volke's Facebook page revealed he was a vocal critic against those who committed violence against women and animals.

Less than a month ago he posted a link to a news article about a man who was bashed for standing up for a group of women who were being threatened.

He commended the man for being a "champion mate".

In June he wanted offenders castrated when two Indian girls were hanged after being gang-raped.
