The mother of a former police officer who allegedly killed two men has been refused bail, as she faces accusations she tried to influence a witness in her son’s trial.

Coleen Lamarre, the mother of accused killer cop Beau Lamarre-Condon, appeared in Sydney’s Downing Centre Local Court by video link from a prison cell on Thursday.

The 63-year-old has been charged with perverting the course of justice but has not yet entered pleas.

She wore prison greens and took copious notes with pen and paper as her barrister applied for her to be released on bail.

The application was refused, meaning Lamarre will remain behind bars for two months unless she makes a further bail application in the state’s highest court.

She is accused of attempting to influence a witness in the trial of her son who, like her, was previously a police officer.

Lamarre-Condon allegedly fatally fired his service pistol at TV presenter Jesse Baird and his flight attendant partner Luke Davies at their inner-city Sydney home in February 2024.

He is then accused of bundling their bodies into surfboard bags and dumping them at a rural property in Bungonia near Goulburn.

The men’s bodies were found eight days later after an extensive search.

Lamarre-Condon, who briefly dated 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 was charged and eventually sacked by NSW Police after handing himself in.

He faces two counts of domestic violence-related murder, and aggravated break and enter. His case will return to court later this month.

The proceedings have become one of NSW’s highest-profile criminal cases in recent years, with suggestions hundreds of witnesses may be called to testify at trial.

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