A former police officer sat outside his ex boyfriend's house for three hours. He wore a delivery driver disguise. Then, prosecutors say, he went inside and killed two men.

Beaumont Lamarre-Condon is 31 years old. He used to work as a police officer in Sydney, Australia. He has pleaded not guilty to two counts of murder. He also pleaded not guilty to one count of break and enter.

Prosecutors say Lamarre-Condon once dated a TV host named Jesse Baird. Baird was 26. The relationship was short. Baird ended it in November 2023.

Prosecutor Brett Hatfield told the court Lamarre-Condon could not let go. He called it an obsessive and jealous infatuation. Hatfield said Lamarre-Condon used a friend's phone to text Baird a lie. He claimed he had cancer. He also stalked Baird. He messed with Baird's car.

By 2024, Baird had a new boyfriend. His name was Luke Davies. Davies was 29. He worked as a flight attendant for Qantas airlines.

Prosecutors say Lamarre-Condon planned the killings. He set his alarm for 4:30 in the morning. He sent a text to a friend. It said he would try to call that night with an update. It said there was no sign he was doing it.

Then, prosecutors say, Lamarre-Condon switched to a burner phone. He picked up a rental car. He put on an outfit made to look like a delivery driver. He waited outside Baird's home for three hours.

Prosecutors say he had a key to the house from before. He used it to get inside. He shot Baird in the kitchen, prosecutors allege. Davies was in the bedroom. Prosecutors say Davies was trying to call for help when he was shot too. Hatfield told the court Lamarre-Condon killed Davies to remove him as a witness.

Prosecutors say Lamarre-Condon had bought a surfboard bag before the killings. They say he used it to hide a body.

After the killings, prosecutors say Lamarre-Condon tried to cover his tracks. He allegedly sent text messages from Baird's own phone to make it look like Baird was still alive.

Police found bloody items in a trash bin in southern Sydney. That is what first tipped them off. Lamarre-Condon turned himself in at a police station about a week later. Officers charged him then.

It took eight days after the killings for authorities to find the two men's bodies. They were hidden in a rural area far from the city.

Lamarre-Condon lost his job with the New South Wales Police after he was charged.

The court also heard Lamarre-Condon once offered to plead guilty to a lesser charge, manslaughter, tied to Baird's death. Prosecutors turned that offer down.

A jury of 15 people was picked for the trial. Normally a jury has 12 people. The judge said the extra three are there in case someone gets sick or cannot continue.

The trial is expected to last three months.

This case happened on the other side of the world from South Texas. But it is a reminder that jealousy and obsession can turn deadly anywhere.

Everyone is presumed innocent until proved otherwise.
