A woman who was found guilty of manslaughter after stabbing her mother over 100 times and decapitating her in Sydney, Australia, has had her 21-year jail sentence reduced.
Jessica Camilleri, who has complex mental health conditions and an obsession with horror films, appealed her sentence on three grounds.
Her representatives argued that the sentencing judge failed to correctly assess the gravity of the crime, did not discount the sentence after her acceptance of responsibility and willingness to cooperate, and that the sentence was excessively harsh, told 7NEWS.
Two out of three judges on the Court of Criminal Appeal granted the appeal, reducing her sentence to 16 years and six months, with a non-parole period of 12 years.
Justice Peter Hamill stated that while the offense was gruesome, it was spontaneous and the result of Camilleri’s complex psychiatric illness.
During her trial, it was revealed that Camilleri had a history of harassing and threatening random people over the phone, including threats to decapitate them.
