Accused killer cop's mum to remain behind bars for days

The 63-year-old has regularly attended court during her son's legal proceedings and indicated she would file an application for her release early next week.

Her solicitor Mickaela Mate sought a two-hour bail hearing on Tuesday, but Judge Lucas Swan said the possibility of hearing the case that soon was slim.

"Two hours on a bail application seems to be somewhat excessive," Judge Swan said in bail court.

"The (court) may give you a date at some point in the near future but it's unlikely to be next Tuesday."

Lamarre will next appear in the Downing Centre Local Court court on May 14 unless her legal team is successful in obtaining an earlier date for a bail hearing.

The court did not hear any details about the allegations, including which witness she is accused of interfering with.

Her son is accused of fatally shooting TV presenter Jesse Baird and his flight attendant partner Luke Davies at their inner-city Sydney home with his service pistol in February 2024.

Police allege the former officer bundled their bodies into surfboard bags and dumped them at a rural property in Bungonia near Goulburn.

They were found eight days later.

Lamarre-Condon, who briefly dated Mr Baird, has pleaded not guilty to their murders.

He joined the force in 2019 and was the first serving NSW police officer charged with murder in decades.

The then-senior constable later handed himself in, before being charged and eventually sacked by NSW Police.

He faces two counts of domestic violence-related murder and aggravated break and enter and his case will return to court on May 29.

The proceedings have become one of the state's most high-profile criminal cases in recent years.

In a previous hearing, Lamarre-Condon said he opposed any orders for a closed court at his trial, saying he "will not be silenced".

The prosecution has hinted at calling hundreds of witnesses to his trial.
