Nikolaus Blyton, 22, and Timothy Cairns, 33, appear in court over murder of Ron Livingstone, 66 TWO men have faced court over the murder of a Gold Coast pensioner who police say may have been slain for his Centrelink money. Ron Livingstone, 66, was stabbed to death on his houseboat at Hope Island in November 2011. His disappearance was never reported and police allege his bank account was raided after his death. Police launched a murder investigation after a tip-off last month. Detectives on Friday arrested Mr Livingstone's son, Nikolaus Blyton, and alleged accomplice Timothy Cairns over the murder. Blyton, 22, appeared in Southport Magistrates Court charged with murder, interfering with a corpse and an unrelated attempted armed robbery at Coomera on June 2. Looking distressed, he nodded to family members in the back of the court before being remanded in custody until his next appearance on July 16. Cairns, 33, was charged with being an accessory to murder after the fact, interfering with a corpse, attempting to pervert the course of justice and stealing. He was also remanded for the next court appearance on July 16. Supporters of both men shielded themselves from the media and refused to comment outside court. Police have found a "possible gravesite" in remote bush land at Coomera and are continuing to search for Mr Livingstone's body.
