People with guns showed up at a business being operated by Shane Ross and Cameron Martin and thousands of dollars' worth of cars were stolen by men in balaclavas before the pair were killed, a Gold Coast court has heard.
Mr Ross, 36, and his Monstr clothing and car business partner Mr Martin, 47, were shot dead at a Tallebudgera park on the Gold Coast in October 2019.
Alleged Lone Wolf outlaw motorcycle gang members Garry James Brush, Nathan John Miller and Brodie Jeet Singh have been charged over the murders and are facing a committal hearing in the Southport Magistrates Court.
On Wednesday, several former employees gave evidence about the operation of Monstr, which Mr Singh's barrister Saul Holt QC claimed was a "dodgy criminal front".
The business sold clothing and had separate operations for custom cars and detailing.
Masked men steal cars
Mechanic Chris Bayer told the court he had worked for Mr Ross and Mr Martin customising vehicles.
He said in 2017 he was working at the Monstr workshop in Sydney, which was holding a car event, when a group of men in hoodies and balaclavas arrived looking for Mr Ross.
The group then drove away with up to 10 display cars worth hundreds of thousands dollars, the court heard.
Mr Bayer told the court they were "not [his] cars" so he did not call the police.
"It could have been hundreds of thousands of dollars' worth of cars, that's a real worry isn't it?" Mr Holt asked.
"Not for me, mate," Mr Bayer replied.
Mr Holt claimed Mr Bayer did not report the incident to police as someone would have done in a "sensible universe".
The court heard people often came to the Gold Coast workshop looking for Mr Ross – known as Rossy – including five large-set "Kiwi" men one day.
There had also been rumours people had attended the workshop with guns, the court was told.
Claims Mr Ross had two phones
Mr Ross's ex-wife Melissa Dominick told the court Mr Ross had a second phone he used to communicate with her and his daughter.
She said he stopped paying child support shortly before his death because his physical health had declined.
Ms Dominick said Mr Ross told her he was "having a hard time with money" and had attempted suicide.
Earlier this week the court heard Mr Ross had been a nominee for the Lone Wolf club in 2012 and had likely become a full member.
Police intelligence indicated Mr Ross had likely "patched over" to the Comanchero bikie gang and became a full member by 2014, the committal hearing was told.
The hearing continues.
