A fashion designer who killed her husband by stabbing him in the chest days before Christmas has sent bizarre religious letters to his parents.
Katie Ann Castel pleaded guilty on Tuesday to the manslaughter of her 35-year-old husband Jarred Castel at their home in Chapel Hill, Brisbane, on December 2017.
Castel was sentenced to nine years in jail for the fatal stabbing which left the couple's five-year-old son Levi without parents.
One month after the fatal stabbing, Castel sent her husband's grieving parents strange letters from behind bars, The Courier-Mail reported.

The letters lasted 12 pages and Castel touched on religious teachings and her experience of being imprisoned.
'The night I lost Jarred they put me in the Brisbane Watchhouse — it was truly the bowels of hell, a concrete cell with a tiny window I couldn't see out of, graffiti on every inch, no underwear and a couple of plastic-covered cushions,' she wrote.
The mother-of-one went on to claim she was a 'novelty' in jail and she was 'the only one as far as the eye can see who doesn't have a drug charge'.
The letters also told her husband's parents to 'rest in Jesus', and quoted a Bible passage saying: 'He who is forgiven much, loves much'.
Castel penned a similar letter to Justice Jean Dalton, in an attempt to explain who she is as a person.
