Behind the smiles of two loving sisters was a devastating medical condition that would lead one to kill the other, reports Jonica Bray.
They were “two halves of a whole”, sisters and soul mates who shared everything from their circle of friends to a computer and the committed love of their parents.
But two years ago Kathleen Worrall wasn’t herself. With her weight increasing, the university student made the decision to stop taking the medication that kept a lifelong hormone disorder in check, leaving her so incapable of dealing with stress she felt homicidal.
Pumped up on testosterone and filled with an unnatural rage after an innocuous argument over a hair straightener, Kathleen spent days planning her sister’s death.
She bought a knife from Kmart and researched the most effective way to kill someone with it.
Days later, infuriated when 18-year-old Susan – who was just a week short of sitting her final Year 12 exams – changed the password on the family computer, Kathleen attacked her as she came out of the shower.
She stabbed her sister more than 50 times, while Susan begged, “No Kathleen, I love you, I love you. Please stop.”
