Schürrer, 35, has reportedly sent a letter to the Australian embassy in Stockholm offering her expertise. Her own very public trial four years ago followed the deaths of two children in Arboga, central Sweden.

The fact that Assange currently risks extradition to Sweden is something that “scares” Schürrer, according to daily Expressen.

Schürrer received a lifetime sentence in 2008 for killing two Swedish children, Max, 3 and Saga, 1, and the attempted murder of their mother.

“She thinks that she has been mishandled, that the Swedish justice system has not taken into consideration her human rights,” said an acquaintance of Schürrer to the paper.

Schürrer’s letter allegedly reads as a warning to the Australian whistleblower.

“There are gaps in legal security here that are obvious and that threaten law and order,” the letter reads, according to Expressen.

According to the woman’s acquaintance, Schürrer believes that Swedish justice system remains at a “medieval level when it allows innocent people to be convicted”.

In her own trial, the Supreme Court, Sweden’s highest legal authority, chose not to grant her the chance to appeal.

However, Assange’s lawyer Tomas Olsson is reportedly not interested in the developments, and has distanced himself from the news.

“I attach no importance to this, it means nothing. This is something she has done of her own accord,” he told the paper.

Meanwhile, Paul Stephens, the Australian ambassador to Sweden, will not comment on the matter, according to his assistant Therese Ryde.

“I’ve spoken to him and he has no comments” she told the paper.
