Son charged with murder of parents does not appear at Queensland court

A 31-year-old man charged with killing his parents at their bed and breakfast will remain in custody in Queensland after being extradited from NSW.

The case against Christopher Puglia was mentioned in the Pine Rivers Magistrates Court on Thursday, following his arrest on Sunday.

Mr Puglia is charged with the double murder of Frank and Loris Puglia, both 59, on Saturday at their Joyner home, north of Brisbane.

Mr Puglia wasn't taken to the court and did not appear by video-link when his case was mentioned. He has been remanded in custody.

After the case was mentioned in court, Queensland police said in a statement that an extra charge of attempted arson would be added to Mr Puglia's list when the case returned to the same court on July 13.

Police said the details of the attempted arson allegation would be released in court on July 13.

The accused is already facing two counts of murder as well as one count of unlawful use of a motor vehicle - relating to him allegedly driving his father's Toyota RAV4 from the scene and into NSW.

Mr Puglia was found by police in the Sydney suburb of Berowra some four hours after his parents' bodies were discovered on Sunday.

Queensland Police allege Mr Puglia killed his parents on Saturday evening before driving to Southport on the Gold Coast.

The vehicle remained there overnight before being driven into NSW on Sunday, it is alleged.

A relative discovered the bodies of Mr Puglia's parents after going to the couple's home for a catch-up.

They died from blunt force trauma, with detectives refusing to speculate on the weapon used despite reports a sledgehammer was found at the scene.

Police do not believe anyone else was involved in the killings.

Meanwhile, police will establish a command post at Wright Reserve, Joyner on Saturday afternoon as they continue to appeal for anyone in the area between 3pm and 6.30pm on the day of the deaths to come forward.
