Parolee jailed for life for Ballarat mother's brutal murder

PAROLEE killer Jason John Dinsley was yesterday jailed for life for the brutal revenge murder of Ballarat mother Sharon Siermans. 

The callous killer, who was on parole when he broke into Ms Siermans’ Doveton Street home and bashed her to death with a cricket bat, will spend at least 32 years behind bars, with a parole period set due to an early guilty plea.

Dinsley and Ms Siermans had only met once in January this year when Ms Siermans rejected Dinsley because he was “filthy” and embarrassing to be around. 

“Fuming” at her rejection, Dinsley broke into Ms Siermans’ home in the early hours of April 6 after recognising the address while walking Ballarat’s streets.

“I started thinking about all the times I’d been rejected in the past and it all just bubbled up,” he later told police.

Supreme Court Justice Elizabeth Hollingworth, who described the murder as “sustained, ferocious and cowardly”, said Dinsley had planned to punish Ms Siermans, walking back to his home in Sebastopol to select an appropriate weapon before returning to seriously assault the single mother.

Justice Hollingworth said Ms Siermans’ four-year-old son awoke to his mother’s screams and at one point saw his mother being dragged into the master bedroom while being bashed.

Once in the bedroom Dinsley held a knife to Ms Siermans’ throat and tried unsuccessfully to rape her. He then continued to bash her to death. 

Dinsley threw away his bloodied shoes and the cricket bat on the way back to his Sebastopol home in a bid to destroy evidence. 

Justice Hollingworth compared the brutal murder to those of Jill Meagher and Sarah Cafferkey, adding that the fact Dinsley killed while on parole was aggravating.

“Murder is the most serious offence known to our legal system and our community and this is an extremely serious example of that offence,” Justice Hollingworth said.

“Unfortunately, the story of somebody who refuses to accept romantic or sexual rejection, who becomes enraged and attacks or kills the person who had rejected them, is all too common.

“Sharon Siermans, like any other person in our society, had the right to choose who she wanted to date, without suffering fatal consequences.”

Dinsley was on parole when he murdered Ms Siermans, having being released from a seven-year sentence he received for the sickening rape of a 52-year-old woman in 2006.

On that occasion Dinsley handcuffed the woman, stuffed her mouth with paper, raped her at knife point and then tried to strangle her.

The Courier understands the parole board planned to cancel his parole at a meeting scheduled two days after Ms Siermans’ murder.

Dinsley stared directly ahead and showed no emotion yesterday as Ms Siermans’ family and friends clapped and cheered when his sentence was announced. 

Outside court, Ms Siermans’ brother, Grant Siermans, said the family was happy that justice had been upheld.
