Eurydice Dixon's killer Jaymes Todd has launched an appeal of his life sentence in prison for murder and rape.

Legal Aid chief counsel Tim Marsh who is also acting for Codey Herrmann, who raped and murdered international student Aiia Maasarwe in January, made the announcement during Herrmann's plea hearing in the Supreme Court on Thursday.

A spokesman for the Supreme Court confirmed lawyers for Todd had applied for leave to appeal his sentence on Monday.

There are striking similarities between the two cases which happened just six months apart and involved young men with no prior convictions for violence ambushing young women, raping and murdering them.
