Ms Floyd's partner told police she had not gotten out of bed on Wednesday and when he woke from a nap about 1.30pm, he discovered she was unconscious.

The 28-year-old spent four days at the Royal Brisbane and Women’s Hospital on life support until her family, some of which travelled from interstate and New Zealand to be by her hospital bed, made the decision to turn her life support off on Saturday night.

“Today I say goodbye to one of my bestfriends Melanie Floyd,” user Jay Humphries wrote.

“Never had I met someone as caring and loving as you. You taught me everything I needed to know on how to be an adult- without you I wouldn’t be in the position I am today with my career.

“Absolutely shattered.”

“Such a big heart and so caring, always giving up your time to make sure others were taken care of, I’ll cherish the times we shared and miss your ability to brighten up my day with your lovely smile."

The woman's 24-year-old partner called Triple-0 to make the emergency alert on Wednesday, but didn't want to be interviewed by police, Detective Inspector Tim Trezise said last week.

"He's exercised his right to silence that he doesn't want to assist us," Insp Trezise told reporters.

Police are treating the death of the hospitality worker as suspicious and are appealing for witnesses to come forward.

At the time, Insp Trezise said police held grave fears for her health, with doctors confirming she had suffered "potentially fatal" brain swelling.

He said the blow to Ms Floyd's head was not obvious, the ABC reported.

"There is some minor, minor bruising on her body but we don't know whether that's recent and we don't know whether that's connected to the significant injury she has to her brain," he said.

Insp Trezise said there were "a number of suspicious circumstances" surrounding the woman's head trauma that resulted in her death. and police did not believe it was a random act of violence.

Homicide detectives were examining the woman's Gallway St apartment to gather more information.

Police are also trying to work out when the pair went to bed and if the attack occurred on Tuesday night.

7 News reported the woman took out a domestic violence order against her Ph-D student boyfriend last year.

Insp Trezise said he could not comment whether it was a domestic violence incident.

"We have an open mind to how these injuries were caused," he said.
