The appeal of the Australian mushroom killer has been rejected, life imprisonment remains.

The Australian Court of Appeal has denied Erin Patterson's appeal against her life sentence for serving poisonous mushrooms that killed three family members. The court ruled that the severity of her crimes warranted no possibility of parole. Patterson had previously been sentenced to life imprisonment with a minimum of 33 years, but the court found the original sentence too lenient. Her defense argued that the incident was a tragic accident, claiming the mushrooms were mistakenly included, but the court upheld the conviction.
