News in 5: Olga Edwards' life in the months before her tragic death; Chris Dawson's family share bombshell theory; Michael Cohen jailed.

-With AAP.

1. The reality of Olga Edwards’ life after children were killed.

According to friends and neighbours, Sydney mother Olga Edwards withdrew herself from society and was deeply depressed after the deaths of her children less than six months ago.

Edwards was found dead on Wednesday, less than six months since her children Jack and Jennifer were shot dead by their estranged father in their home.

She was discovered by police about 10am on Wednesday after they responded to a concern for welfare report at the same house her children were murdered earlier in the year.

NSW Police say the death is not being treated as suspicious.

Edwards was devastated after her estranged husband John shot their 15-year-old son and 13-year-old daughter at their West Pennant Hills home before killing himself in July.

The Russian-born mother had worked as a solicitor in Woolwich and was taken into the care of friends following the murder-suicide.

A neighbour told the Daily Telegraph she was struggling, often remaining inside with the blinds down all day. She would sometimes not open the door when neighbours brought her food.

Tragically, the neighbour told of how Edwards would fall asleep on Jack or Jennifer's bed at night: "She couldn't get over never seeing them again."

Her mother, who rushed to her daughter's side following the July tragedy, had only just returned to Russia this week and Edwards' had promised to move back there after Christmas.

Another friend told the Daily Telegraph that although Edwards was in heavy counselling, she was unable to cope.

"Life was too hard without Jack or Jennifer," the friend said.

"She was dreading Christmas without the kids and planned to leave Australia for good. She had organised to spend Christmas Day at the house to be close to Jack and Jennifer."


Detective Superintendent David Waddell said officers who had been investigating the murder-suicide went to the West Pennant Hills home on Wednesday to check on Ms Edwards when they found her body.

She had been receiving support from police, organisations, family and friends but "obviously things took their toll," he told 2GB radio.

AAP understands her overseas family is being notified.

The Russian-speaking community rallied around Ms Edwards after the murders and have now sent their condolences to her family and friends.

Russian speakers Australia told AAP the last several months must have been "unbearable" for her.

After the murder it emerged John Edwards, a financial advisor, had legally purchased the powerful handguns used in the murders months earlier while he was involved in a drawn-out custody battle over the children.

His actions shocked the nation, prompting politicians and activist groups to launch reviews of firearms and domestic violence legislation.

2. Chris Dawson's family's bombshell theory.

Just a week after Chris Dawson was charged with the 1982 murder of his wife Lynette Dawson, his family have made a chilling suggestion about what happened to her.

Chris Dawson's previous story was that Lyn ran away, leaving her whole life behind - including the couple's two children - but the Dawson family have now suggested she was murdered by serial killer Ivan Milat.

"Milat… is alleged to have killed several women around the same time and in an area Lyn was seen," Mr Dawson’s brother Peter told 7 News.

Milat, who is currently serving seven consecutive life sentences, killed backpackers and hitchhikers, and Peter Dawson pointed out that Lyn didn't drive.


7 News reported Peter sent them a list of missing women all named in coronial inquests as possible Milat victims, suggesting Lyn could be too.

Clive Small, former assistant police commissioner who led the Milat investigation, said Milat kept souvenirs from his victims and picked up victims from the Liverpool area, which did not fit Lyn's case.

Dawson, now 70, has been charged with the 1982 murder of his wife.

Lyn was 33 when she went missing in January 1982 leaving behind two young daughters.

Detectives from the NSW homicide squad began re-investigating her suspected murder in 2015 and sent a brief of evidence to the Director of Public Prosecutions in April this year.

Much of the additional material surfaced as a result of The Australian newspaper’s investigative podcast, The Teacher’s Pet.

Dawson, a Newtown rugby league player in the early 1970s, has long been a suspect in the case but denies any involvement in his wife’s disappearance.

3. Trump's ex-lawyer jailed for three years.

US President Donald Trump's former lawyer has been sentenced to three years in prison.

A New York judge says Michael Cohen deserves a harsh punishment for crimes including tax evasion, lying to Congress and arranging illegal payments to silence women who posed a risk to Trump's presidential campaign.

District Judge William H Pauley III on Wednesday rejected arguments by Cohen's lawyers that he should be spared jail because he co-operated in multiple federal investigations involving Trump.

Cohen had said his "blind loyalty" to Trump made him feel a duty to "cover up" the president's "dirty deeds".

Cohen's crimes included evading $US1.4 million ($A1.9m) in taxes and misleading Congress about his talks with Russians about a Trump skyscraper project in Moscow.


Trump had called for a tough sentence for Cohen, whom he labelled a liar.

The judge said Cohen's co-operation with prosecutors "does not wipe the slate clean" of his crimes.

Judge Pauley said Cohen "appears to have lost his moral compass" and that the lawyer "should have known better" than to dodge taxes, lie to Congress and violate campaign finance laws.

After the case, an adviser to Cohen said the former political fixer will "state publicly all he knows" about Trump after special counsel Robert Mueller completes his investigation.

Lanny Davis said Cohen "continues to tell the truth about Donald Trump's misconduct over the years".

Cohen has been ordered to hand himself in on March 6 to start his sentence.

4. Britain's May wins vote of confidence.

British Prime Minister Theresa May has won a vote of confidence in her leadership.

The result of the Conservative MPs votes was 200-117.

At a closed meeting with Conservative MPs before they were due to decide her fate, May announced she would not take the party into the next election due four years from now.

"She did say she wouldn't be fighting the next general election," Work and Pensions Secretary Amber Rudd told reporters.

Less than four months before Britain is due to leave the EU on March 29, the country's exit is in chaos.

5. SA teacher jailed for sex with student.


An Adelaide teacher who admitted having a sex with a student has been jailed for more than four years for her "manipulative and unforgivable" breach of trust.

Sonia Mackay, 43, faced the District Court on Wednesday after pleading guilty to the persistent sexual exploitation of a 17-year-old boy.

In sentencing, Judge Liesl Chapman said Mackay had struck up a sexual relationship with a student in her year 12 English class.

Over the course of a month, the pair engaged in sexual activity "many times" at Mackay's house, in her car, at the victim's house and in public areas around Adelaide.

They drank alcohol and smoked cigarettes and cannabis together, and Mackay bought the boy presents and a nose piercing.

The boy said in a victim impact statement last month that Mackay also branded his flesh with a cigarette, and that the relationship caused him to withdraw from family and friends.

His mother said her son stopped coming home for days at a time and, when he did come home, Mackay called him and threatened self-harm.

The boy's parents became suspicious and approached the school principal, who reported the matter to police.

When confronted by his mother, he admitted the sexual relationship and said he was in love with Mackay.

Judge Chapman said Mackay, whose marriage had recently broken down, was overwhelmed by grief, sadness and confusion at the time.

But she said the crime had breached the trust of the victim, his family, her employer and the school community.

"Your behaviour was manipulative and unforgivable," she told Mackay.

"You seem to have lost touch with reality and were living in some sort of fantasy land.

"In light of what you were doing and the way you were doing it, it is evident to me that you could not have been thinking straight."

Mackay and several supporters cried as Judge Chapman jailed her for four years, fives months with a non-parole period of two years, one month.

Mackay, a mother of two young children, will be eligible for parole in early 2021.
