A teenager allegedly bashed her grandfather to death with a frying pan after he criticised her mother's parenting skills on Anzac Day.
Tayla Perkin, 18, is accused of bludgeoning her war veteran grandfather Lyall Ellis, 89, after an argument turned physical in his Esperance home in Western Australia.
Footage shows the teen boarding a plane under police guard to be flown to Kalgoorlie prison before her next court appearance, reports the West.
Perkin, who was living with her grandfather at the time of the alleged attack, reportedly flew into a rage during the row.
Ellis was rushed to Esperance Hospital - only a minute's drive away - but died on Tuesday night, the Daily Mail reports.
Major Crime Squad officers from Perth established a crime scene outside the home.
It is understood Perkin's younger brother, a toddler, was also home at the time.
Perkin was initially charged with grievous bodily harm on Wednesday, but the charges were upgraded to murder on Thursday.
The 18-year-old wept in court, where she was supported by her mother and a friend.
