The man accused of murdering Victorian woman Hannah McGuire claims the 23-year-old hit her head on the floor and died after an argument became physical. But barrister Glenn Casement claimed O’Keefe knew McGuire was in the ute because Young had told him she was dead. Casement claimed O’Keefe saw McGuire on the floor and devised a plan with Young to move her body to Scarsdale. Casement claimed O’Keefe then lied about his involvement to avoid being charged as an accessory to murder. He claimed Young told him McGuire was already dead as she had been suffocated.
