A woman accused of murdering mother Krystal Marshall south of Adelaide last year has been granted bail.

The 38-year-old woman was found dead at the scene of a house fire on Barracoota Crescent at Aldinga Beach on October 20.

Krystal Marshall’s ex-wife, Anastasia Narelle Marshall, 29, and Jonathan Paul Parker, 48, have been charged with her murder.

On Friday, Supreme Court Justice Tim Stanley granted Ms Marshall bail with strict conditions, including orders not to contact witnesses.

Justice Stanley accepted her defence lawyer’s submission that the accused was not a flight risk and had no relevant prior offending history.

“I cannot emphasise enough that you comply with all of the conditions of bail,” he told Ms Marshall.

Bail was ‘appropriate outcome’, lawyer says

Ms Marshall’s lawyer Nicholas Vedasz told the court his client was “reliable” and a “model prisoner”.

“The case prosecution wishes to pursue is weak in my respectful submission,” he said.

The prosector said the alleged offences were serious and included arson and the destruction of human remains.

Speaking outside of court, Mr Vedasz said it was an “appropriate outcome”.

“She [Ms Marshall] is happier to be out and she will be out,” he said.

“The evidence does not support a conviction in my respectful submission, she is innocent and there’s no evidence to indicate she’s not.”

The matter will return to court in July.
