Police investigate threatening emails sent to Chris Dawson’s brother and lawyer

Threatening emails and phone calls to the offices of alleged wife-killer Chris Dawson’s brother and lawyer are being investigated by police. 

Chris Dawson’s brother Peter Dawson and his lawyer Greg Walsh both claim to have received ‘threatening’ and ‘filthy’ emails and phone calls from unidentified males. 

Peter Dawson, who is also a lawyer, said the anonymous threats were ‘obscene’ and expletive-laden rants about what would happen to his brother behind bars. 

Mr Dawson told the Daily Telegraph he had contacted police because the vile emails and phone calls were going through to his female staff.  

‘The language is obscene, it’s absolutely disgusting,’ he told the publication. ‘It’s mostly what they are going to do … and that I should be included in jail.’

Police confirmed officers from the St George command in Sydney’s south were investigating reports ‘after a man received several threatening emails’.    

Investigators are working to trace the origin of the emails and calls.

The threatening calls follow the dramatic arrest of Chris Dawson on Wednesday.

The 70-year-old former PE teacher was extradited to Sydney from Queensland and charged with murdering his wife Lyn overnight on January 8 and 9 in 1982.

On Saturday, Joanne Curtis, the former partner of Chris Dawson appeared in public. 

Ms Curtis, now 54, was just 16 when she began an affair with Dawson, her 32-year-old teacher, and 17 when Dawson’s wife Lyn disappeared on January 9, 1982. 

The schoolgirl moved into the family home and two years later the pair married and later had their daughter Kristen, now aged in her 30s, before they split in 1990.

Two coroners in years past heard Dawson, 70, wanted his wife out of the way so he could carry on his affair with Ms Curtis. 

Ms Curtis will be a star witness at Dawson’s murder trial after she gave police crucial new information that, along with other new accounts, allowed him to finally be charged. 

The new evidence helped police ‘tie pieces of the puzzle together’, NSW Police Commissioner Mick Fuller said.

The dramatic arrest followed two coronial inquests, a viral podcast called 'The Teachers Pet' and a renewed police investigation. Chris is pictured with Lyn and daughter Shanelle

A former babysitter for the Dawsons, Bev McNally, is another new witness who has given statements to police, along with a third woman who recently met with detectives for the first time. 

They are understood to have corroborated Ms Curtis’ new evidence enough to convince prosecutors to charge Dawson with murder.

Police now believe she was buried in bushland in Sydney’s north, despite a recent excavation of her former Bayview home as detectives searched for evidence. 

Allegations that Dawson was violent towards Lyn emerged when he appeared in Southport Magistrates Court on Wednesday.

The court heard there had been evidence of domestic violence.

Dawson was then extradited to Sydney where he faced court again and was remanded in custody until a bail hearing on December 14.

His lawyer Greg Walsh said outside court the defence would argue Ms Dawson simply left her husband and was subsequently seen alive several times. 

Mr Walsh also said they would rely on ‘two very ­important Bankcard transactions on Lyn’s bank account in the weeks after her disappearance’.

Joanne Curtis moved into the Dawson's family home after Lyn disappeared. Two years later the pair married and later had their daughter Kristen (pictured as a baby),  before they split in 1990

Ms Curtis was on holiday with family and friends at South West Rocks on the NSW mid north coast when she says Dawson called her on January 9 or 10.

She told police Dawson said: ‘Lyn’s gone. She’s not coming back. I need you now. Come and live with me and the girls at Bayview.’ 

She moved back into the Dawson family home as his lover and effectively became mother to his children, four-year-old Shanelle and two-year-old Sherryn.

Ms Curtis, who wore Mrs Dawson’s clothes as well as taking her place in the marital bed, told police in 1998 the situation was ‘very strange for everyone.’

She married Dawson at their home in Gilwinga Drive on January 15, 1984 with Paul and Marilyn as witnesses.

Dawson gave Ms Curtis one of his missing wife’s rings to wear for the ceremony. He was 35 and she was 19.

The couple later sold the Bayview property and moved to Queensland where they had Kristen in 1985. 

During the pair’s short marriage Dawson allegedly treated Shanelle and Sherryn as princesses and largely rejected Kristen.

‘He was even more possessive of me and regretted Kristen,’ Ms Curtis told a coroner in 2003. ‘He wanted me to himself. He just wanted her out of the way.

‘I did as I was told. He chose what I wore. If I was going somewhere, he would have to approve it.
