Two years ago, Erelle Mason and her partner Scott Martin experienced the unimaginable pain of losing a child to sudden infant death syndrome.

Baby Mason Martin was just three-weeks-old when he passed, and his death prompted calls for a review of WA's forensic services system.

His grieving family was forced to delay his funeral three weeks due to WA's only forensic neuropathologist taking leave during the holiday period, and Erelle was only able to hold her child three weeks after his body had been kept in the mortuary fridge.

Baby Mason's family has now been forced to endure a second tragedy.
