The duo remained at the scene for hours as Ms Howe's body burned. Her skeletal remains were not found until June 7, two days after Ms Howe's daughter went to police, worried her calls and texts to her mum had not been returned. A Brisbane Supreme Court jury heard there had been tension over suspicions Ms Howe had stolen property from the two men. "She would have had no inkling she was about to be set upon," Justice Burns said. "These were, in my assessment, acts of extreme cowardice, savagely assailing a 57-year-old grandmother in her own home," Justice Burns said.
