More than a month after leaving the White House, Donald Trump is set to make his first public appearance as a former president.

And he is set to do so at the biggest event for America's political conservatives.

Mr Trump is due to speak on Sunday afternoon at the Conservative Political Action Conference (CPAC) in Florida, his first address since leaving office.

CPAC is often used as a launching pad for Republicans looking to run for president, so all eyes will be on Mr Trump.

While he has hinted at another run for the White House, CPAC would give him a large platform from which to make an announcement.

"I think the broader point will be: Here's where the Republican Party and conservative movement and the America First movement goes from here," Trump adviser Jason Miller said.

"In many ways, this will be a throwback to 2016, where the president ran against Washington.

"Here we'll see the president address the fact that the only divide in the Republican Party is between the elites and the conservative grassroots in the party."

Presidential candidates usually never announce a run this early, but Mr Trump has hardly sought to follow typical conventions of political behaviour.

Keenly watching will be other Republicans interested in running for president themselves, but not wanting to face off against Mr Trump in a primary.

They include former Secretary of State Mike Pompeo, Senators Ted Cruz of Texas and Josh Hawley of Missouri, and Governors Ron DeSantis of Florida and Kristi Noem of South Dakota.

CPAC will be the first time Mr Trump has stood in front of a microphone since leaving office. The bans he received from Twitter and other social media platforms have largely muffled his efforts to voice his thoughts in recent weeks.

On Friday a panel will discuss the topic of "Protecting Elections: Why Judges & Media Refused to Look at the Evidence".

Then on Sunday morning, speakers will talk about the "Failed States" of Nevada, Georgia and Pennsylvania, all of which narrowly voted for Joe Biden.

The conference, to be held in Florida, will feature prominent Republican politicians from around the country.

But none of those who supported impeaching Mr Trump have been invited.

Also not attending is Mike Pence, after his falling out with Mr Trump on January 6.

And Senate Minority Leader Mitch McConnell, who lambasted Mr Trump over his behaviour leading up to the Capitol riots, is not going either.

Both have previously been mainstays of the conference.

The theme of the event is "America Uncanceled", but already one guest has been uninvited for his hateful views.

Rapper Young Pharoah was due to appear, but his appearance was cancelled over his anti-Semitic views.

"We have just learned that someone we invited to CPAC has expressed reprehensible views that have no home with our conference or our organisation," CPAC said in a statement.

"The individual will not be participating at our conference."

An 82-year-old man charged with murdering his wife inside their Gold Coast home is undergoing toxicology testing as authorities investigate whether drug use may have played a role in the alleged attack.

Robyn Beever's daughter discovered her mother's bloodied body inside the garage of the Varsity Lakes home at 1.30pm yesterday during a visit to check on the elderly couple.

The victim's husband Max Beever was taken to the Gold Coast University Hospital where he remains in a stable condition and under police guard.

Overnight, he was charged with murdering his wife.

Speaking at a press conference this morning, Queensland Police's Detective Inspector Chris Ahearn said Mr Beever "doesn't have any significant physical injuries" but has undergone toxicology testing.

Detective Inspector Ahearn said the elderly man is "in a distressed state" and has refused to be interviewed by police.

He declined to detail any medical conditions the 82-year-old may have, but said "the physicality of that gentleman is something that continues to be under investigation".

He noted that the toxicology results would likely "give us a clearer picture on what might have gone on".

Neither Mr Beever nor his wife have any criminal history and this is the first time they have had formal contact with police.

The crime scene at Gerona Circuit home will likely remain in place into tomorrow, as investigators comb the home for objects that may have been used during the alleged attack.

An axe and a belt are among the items found at the property currently undergoing forensic examination.

The post mortem of Ms Beever's body, expected to be conducted today, will provide a more exact time of death but Detective Inspector Ahearn said it is believed Ms Beever likely died yesterday, or possibly as far back as 6pm the night before.

Detective Inspector Ahearn has called for anyone who was in the area during that time to come forward, especially anyone who may have heard anything that may assist investigators.

He described Ms Beever's death as "a tragic incident with a tragic outcome".

"Our thoughts go out to the family and friends of this woman," he said.

The couple's daughter who discovered the body is "extremely upset" and is being provided with support.

Mr Beever's murder charge was heard in Southport Magistrates Court today, with the court hearing he remained in hospital and was unable to appear.

No application for bail was made and the matter was adjourned until next March 5.

One of Pompeii's oldest frescoes has been restored to its colourful former glory using the help of laser technology.

The House of the Ceii, excavated between 1913 and 1914, is one of the city's rare ancient domus — single family residences which were built complete with an atrium and peristyle — dating to the late Samnite period in the second century BC, according to the Archaeological Park of Pompeii.

The house, thought to have been owned by a local magistrate, was elaborately decorated over several levels.

A large fresco "adorns the back wall of the garden and was in view for those entering this luxurious house," Massimo Osanna, interim director of the Archaeological Park of Pompeii, told CNN.

Mr Osanna added that the picture features an animated hunting scene with wild animals arranged on several levels of the house.

There are images of temples, statues and animals of the Nile Delta, he added.

Created by anonymous artists, the decor "can also be seen on the walls of the Pompeian gardens, in order to create an illusion of enlarging the dimensions of such spaces and evoke an idyllic and suggestive atmosphere," he said.

But over the years, the historic house fell into disrepair.

A lack of proper upkeep and unsuitable restoration practices had seen progressive deterioration of the images, and damage to the frescoes, especially in the humid, lower parts of the building.

Using lasers to clean the painting's pictorial film, experts were able to clean portions of the painting, including the fresco's botanical decoration, while abraded parts of the art were recovered through precise pictorial retouching.

Work on the house started in September, and is ongoing, according to the Archaeological Park of Pompeii.

"In this case, in all probability, the exotic and religious theme of the paintings testified to a link and a specific interest that the owner of the domus had for the Egyptian world and for the cult of Isis (an ancient Egyptian goddess), present in Pompeii in the last years of the city's life due to a very influential college in the city," Mr Osanna added.

The ancient city of Pompeii is one of Italy's top tourist attractions, and a UNESCO World Heritage site.

Much of the Greco-Roman city is still covered in debris from when Mount Vesuvius erupted and blanketed the city in ash and pumice almost 2000 years ago.

And experts are still uncovering tidbits that give clues to what life was life when the city was functioning.

In December, archaeologists uncovered a frescoed hot food and drinks shop that served up the ancient equivalent of street food to Roman passersby.

The investigation into Melissa Caddick's alleged Ponzi scheme is continuing despite her being presumed dead this morning.

DNA evidence confirmed a foot found washed up on a beach on the NSW South Coast was that of Ms Caddick's.

But the Australian Securities and Investment Commission said its investigation into her alleged crimes is continuing.

"ASIC's priority is to seek the return of funds to investors in the most efficient way possible," the statement read.

"ASIC will continue to work with the receivers and provisional liquidators to prepare for the Federal Court hearing listed on 7 and 8 April.

"ASIC's considers the hearing should go ahead as a priority to seek return of funds to investors."

A human foot in a shoe was found by campers on the shoreline at Bournda National Park near Tathra on Sunday.

Analysis using DNA from Ms Caddick's toothbrush matched the foot.

Offshore drift modelling found that a body which entered the water near Ms Caddick's home in Dover Heights in Sydney may have drifted to the South Coast over time.

Ms Caddick, 49, disappeared on November 12 last year after leaving her home for what her husband believed was a morning run at 5.30am.

She and her family lived in affluent Dover Heights in Sydney's eastern suburbs.

She had been under investigation for allegedly running a Ponzi scheme, using millions from investors to make lavish personal purchases.

Her purchases included expensive holidays to the US ski resort town of Aspen, as well as couture gowns, designer clothes, shoes and handbags, and jewellery.

Her five-bedroom home was bought in 2014 for $6.2 million.

The Australian Federal Police (AFP) raided her home as part of an ASIC investigation the day before she disappeared.

Further investigations have found neither Ms Caddick nor her business held a current AFS licence, required under Australian law to provide financial services.

Instead of investing funds from investors, Ms Caddick allegedly transferred money from the business into her personal accounts.

When Melissa Caddick vanished from her home in Sydney's Dover Heights on November 12, it sparked dozens of conspiracy theories.

And the discovery of her foot on a beach on the NSW South Coast on Sunday has raised as many questions as answers.

But Ms Caddick's story started well before her disappearance, and has not ended now her remains have been found.

The timeline of Melissa Caddick's story

May 6, 2009: Court documents indicate the first of Melissa Caddick's "suspected contraventions" is on this date. That year she sets up her own financial firm, but without the necessary financial services licence to do so.

Over the next 11 years she collects tens of millions from clients, who all believe they are investing.

2013: Ms Caddick marries Anthony Koletti, a hairdresser she met at a salon in Bondi Junction.

2014: Ms Caddick pays $6.2 million for a five-bedroom home in Dover Heights.

August 13, 2020: According to the Sydney Morning Herald, one of Ms Caddick's investors strikes up a conversation with another patient in a dentist's waiting room. The patient tells her Ms Caddick has been using her financial services licence.

The investor later reports Ms Caddick to the Australian Securities Investment Commission.

November 11, 2020: Officers from ASIC raid Ms Caddick's home in Dover Heights. The raid takes up most of the day. Officers leave with couture gowns, designer clothes, shoes and jewellery. It is the last day Ms Caddick is seen alive.

November 12, 2020: Ms Caddick's son hears the front door of their home close at 5.30am. He assumes it is Ms Caddick going for a morning run.

November 13, 2020: Ms Caddick is reported missing to police by her husband, 30 hours after her disappearance.

February 21, 2021: Campers find a shoe containing a decomposing foot on the shoreline south of Tathra, on the NSW South Coast.

The former Minneapolis police officer convicted of third-degree murder in the 2017 fatal shooting of Australian woman Justine Ruszczyk, who called 911 to report a possible sexual assault, has asked the Minnesota Supreme Court to hear his appeal.

Mohamed Noor has filed a petition asking the state's highest court to overturn his conviction in the death of Ms Ruszczyk, after a Court of Appeals panel upheld the jury's decision earlier this month.

Some legal experts say the third-degree murder charge applies only when a defendant's actions put multiple people at risk, but the appellate panel said it can apply when a defendant's actions are directed at one person.

LIVE UPDATES: Body of missing woman and fraudster Melissa Caddick found

The state's Supreme Court must now decide whether it will hear the appeal.

If it does not, the appellate decision will stand, the Star Tribune reported.

Ms Ruszczyk called 911 the night of July 15, 2017, to report a possible sexual assault in an alley behind her house.

Officers Matthew Harrity and Noor were dispatched to the scene and arrived at 11.37pm.

Prosecutors said Noor was sitting in the passenger seat, pulled out his gun and shot across the vehicle to hit the unarmed Ms Ruszczyk, who was outside the driver's side door.

Noor admitted shooting Ms Ruszczyk but claimed he did so in fear he and his partner were being ambushed.

Noor is currently serving a 12-and-a-half-year prison sentence for third-degree murder.

Ties to George Floyd case

The issue could have implications in the upcoming trial of former Minneapolis officer Derek Chauvin, who is charged with second-degree murder and manslaughter in the May 25 death of George Floyd.

The judge in Mr Chauvin's case had dismissed a third-degree murder count last October, saying it didn’t apply because Mr Chauvin’s actions were directed at Mr Floyd alone.

But prosecutors are seeking to have it reinstated, saying the appellate decision shows the third-degree murder count can apply to Mr Chauvin as well.

The Minnesota Court of Appeals is scheduled to hear arguments in that case on Monday.

Jury selection in Mr Chauvin’s trial is scheduled to begin March 8.
