The heartbroken sister of slain Queensland teenager Larissa Beilby has told a memorial service that justice must be served.
Deanna Beilby says the horrific death of her 16-year-old sister, whose body was found in a barrel south of Brisbane last month, has left an enormous hole in her heart.
"As a nation, we've been brought together under the most horrific circumstances and I hope we stand together until justice is served," Ms Beilby told 100 mourners at a service to honour the teenager on Sunday, according to the ABC.
Ms Beilby remembered her sister as a funny, smart and cheeky girl, with Larissa's family urging people to honour her by carrying out a random act of kindness to a stranger in the week ahead.
Larissa's body was found in a barrel in the back of a ute near Logan last month, sparking a manhunt for 34-year-old Zlatko Sikorsky.
It's alleged Sikorsky abandoned her remains at a gated Gold Coast residential estate before fleeing in a 2014 silver Holden Commodore sedan.
Police found that car at Eight Mile Plains, about 20 minutes north, on Friday and will undertake forensic testing.
Sikorsky was arrested after a 28-hour stand-off with police at a Sunshine Coast unit and charged with murder, torture, deprivation of liberty and interfering with a corpse.
Police later charged him with attempting to murder another woman.
His lawyer Brendan Ryan has told reporters Sikorsky intends to defend the charges relating to Larissa's death, suggesting she died as a result of misadventure.
