The father of a 16-year-old girl allegedly murdered by Zlatko Sikorsky and found in barrel has opened up about her death.
The father of murdered schoolgirl Larissa Beilby says her death hit him "like a sledgehammer".
Peter Beilby said he was out searching the streets six days ago when he got the news his 16-year-old daughter's body had been found in a barrel in the back of a ute south of Brisbane.
"It was like a sledgehammer hitting me, I was just broken," Mr Beilby told Nine News last night.
"I couldn't put it into words, it was like a physical thing."
It's the first time he has spoken publicly about his daughter's death, appearing at a Brisbane graffiti wall on Monday night where friends of Larissa have painted a mural in her honour.
Mr Beilby laid a rose at the site, saying he was "still processing" what had happened.
"It breaks my heart thinking how she must have been feeling, like, when she knew what was going on."
"I'm picking the things that I process but I just want to do Larissa honour now, bury her and put her to rest.
"We're going to cremate her and then I'm going to take her back to Adelaide and bury her with her mum."
Mr Beilby said his relationship with his daughter had become strained in the months leading up to her death with Larissa moving into community housing before Easter.
However, he said he never stopped loving his little girl and was haunted by what had been done to her.
"If someone was to take your daughter and treat her like that I just don't know how to get my head around it," he said.
Friends and family of Larissa want to get away from the image of her as the "girl in the barrel" and remember the "happy, cheeky adventurous girl" they knew as "Riss".
A legacy fund which has attracted hundreds of donations since it was launched on June 30 has raised more than $15,500.
Mr Beilby said the money would be donated to a child protection charity.
Zlatko Sikorsky, 34, has been charged with murder, torture, deprivation of liberty and interfering with a corpse over Larissa's death.
He was arrested last Saturday after a 28-hour standoff with police on the Sunshine Coast. However, his lawyer on Monday claimed her death had been due to "misadventure" and they would be fighting some of the charges.
Police searching for car
Detectives investigating Larissa's death have meanwhile put out a fresh call for information about a vehicle of interest.
They're searching for a 2014 silver Holden Commodore sedan with a sunroof and Queensland registration plates 966 WKB which may have since been removed or replaced.
Anyone who may have noticed a car with a similar description parked in a suspicious location or abandoned is urged to come forward.
