Anti-Islamic State fighter Ashley Dyball has been remanded in custody charged with murder over the disappearance of Samuel Thompson.
The 25-year-old Albany Creek man was taken into custody late on Friday night, charged with murder and interfering with a corpse.
He appeared in Brisbane Magistrates Court on Saturday where his matter was adjourned until May 15.
The former professional power lifter had fought IS forces in Syria during 2015 before returning to his home state of Queensland.
Samuel Thompson, 22, was last seen on March 7 and was reported missing by his family to police.
A team of 40 detectives has been working the case and have searched an Ipswich tip and a Bald Hills home in relation to the man's disappearance.
A car similar to the one spotted on CCTV at the car park of the Deep Water Bend Reserve at Bald Hills, where Mr Thompson was last seen, was seized from an Albany Creek home on Wednesday night.
Mr Thompson's distinctive orange 2016 Ford Mustang was also spotted in the car park that day.
He was the victim of an unsolved robbery in Brisbane last September, in which his car was stolen and police are investigating whether his disappearance was linked to that crime.
Mr Dyball is the second man to be charged in relation to Mr Thompson's disappearance.
Roberto Vincenzo Boscaino was charged with murder and interfering with a corpse on Thursday.
The 23-year-old did not apply for bail when his matter came before Brisbane Magistrates Court on Friday morning.
The Bald Hills man appeared to tremble during his first few moments in the dock but sat calmly as his matter was adjourned to the committal call-over list on May 8.
Outside court, Mr Dyball's lawyer Alex Jones said his client was "upset at the situation".
Mr Jones said he had spoken with Mr Dyball's family who had found news that their son had been charged "quite shocking".
