FORMER security workers Vladimir 'the Russian' Garcia and Cameron Andrew Stewart have been found guilty of the brutal murders of husband and wife Alexander and Sue Davie.
The Davies were found murdered on May 5, 2009 in two separate locations.
Mr Davie was found in a toilet cubicle of a Burleigh business he had been patrolling.
His hands were tied behind his back with zip ties, he had been beaten, stabbed 10 times and the word "dog" was written in blood on the stall door.
Mrs Davie was located on the bed in their Robina home, beaten with a hammer and stabbed.
The jury went out to deliberate at 11.45am Wednesday and returned with the verdict about 11am Thursday.
In 2006, Stewart and Cameron were employed by SSS Security, until Mr Davie, their employer, accused them of stealing guns.
Later the same year both men spent six months in remand for an unrelated crime, for which they blamed Mr Davie.
