A Sydney cop who handed himself in to New South Wales police on Friday has since been charged with two counts of murder, following the "suspicious" disappearance of two young men.
It comes after bloodied items belonging to Channel 10 star Jesse Baird and his partner, Qantas attendant Luke Davies, were found in a skip bin in Cronulla on Wednesday, 30km from their home.
The items included a phone, blood-stained clothes, keys, money cards, and an expensive watch.
Police raid three properties across Sydney
On Thursday afternoon, police searched Baird's home in Paddington, finding a "significant" quantity of blood.
"After entering the property, officers immediately established a crime scene," police said.
Officers also searched Davies' home in Waterloo, but found nothing there.
Then on Thursday night, officers raided and seized several items at the Balmain home of wanted man Beau Lemarre, 28.
Lemarre is a police constable and former celebrity blogger.
NSW police confirmed he had taken sick leave for the entire week.
Subsequently, on Friday morning, NSW police said a man, 28, had presented to Bondi Police Station about 10:30am.
He is "assisting with inquiries", they said.
Police also asked the public for sightings of a white Toyota Hiace, registration CW82PM this week.
"Detectives are appealing for anyone with information to come forward," police said.
The homicide squad is also investigating.
A WhatsApp twist
Police said Baird had been active on messaging app WhatsApp as recently as Tuesday night.
The Daily Mail Australia reported Lamarre's phone had been switched off Thursday night.
But he was "last seen today at 9:55am" on WhatsApp - meaning his phone had been turned on again Friday morning, according to the Daily Mail.
Detectives were seen door-knocking homes near Lamarre's Balmain home on Friday.
"If Jesse's seeing this, we'd ask him to contact us, as well as anyone that might know the whereabouts of Jesse," said Det Sup Jodi Radmore.
'Suspicious' circumstances
NSW investigators said on Thursday the disappearance of Baird and Davies is "being treated as suspicious".
Lemarre had previously dated Baird, and relatives told police their break-up was "bitter".
Baird had also reportedly told his friends he was being stalked.
Just before the couple went missing, a white van was spotted outside Baird's Paddington home.
Police believe it's linked to Lemarre, according to 7News.
In addition, witnesses described hearing a loud argument at the property on Monday morning.
Australian media reports Lamarre was obsessed with celebrities - even attending the Golden Globes in 2016, where he took selfies with stars including Selena Gomez, Ryan Gosling, and Kirsten Dunst.
He reportedly became a police officer in 2019.
A friend of Baird and Davies told Australian media they'd been dating for less than a year.
One of Davies' colleagues told News.com.au that "everyone at Qantas is so shocked".
Qantas said in a statement they were providing support to staff.
"Our thoughts are with family, friends and colleagues of our crew member at this very difficult time," the airline said in a statement.
