WA man on trial for tongue bite Five people were having a boozy house party when one of the guests had a large chunk of his tongue bitten off during a scuffle, a Perth court has heard. William Guthrie is on trial in the District Court of Western Australia charged with grievous bodily harm. FIVE people were having a boozy house party when one of the guests had a large chunk of his tongue bitten off during a scuffle, a Perth court has heard. William Guthrie is on trial in the District Court of Western Australia charged with grievous bodily harm over an incident in November that left Daniel Robert Paul Kneebone with life-threatening injuries. Mr Kneebone testified on Monday that he did not recall the altercation but remembered he and his girlfriend, Sarah Roche, were leaving the house when it happened. She was also drunk and had fallen asleep beside another woman in a bedroom before the couple decided to leave, and was then waiting in her car for Mr Kneebone. Mr Kneebone said he woke up in the driveway with scrapes on his hands and knees, and then realised his mouth was bleeding. ``I had a lot of blood on me," he said. Images were shown to the jury of Mr Kneebone's swollen and bruised lips, and his severed tongue. The state alleges a scuffle occurred when the host tried to get Mr Kneebone to leave and called Guthrie for help. Under cross-examination, Mr Kneebone denied fighting with the host, trying to ``wind up" Guthrie, and sticking his tongue in anyone's ear. Ms Roche wiped tears from her eyes describing how she screamed when she saw her boyfriend's bloody face. Prosecutor Barry Murray said medical evidence would prove the curve of the bite meant Mr Kneebone could not have bitten himself. Mr Murray said a medical expert would explain later in the trial that if the injury had not been treated, Mr Kneebone could have died. Defence lawyer John Bougher suggested it was the host who caused the injury, not Guthrie. Regardless of who was responsible, the question had to be raised as to what Mr Kneebone's tongue was doing in someone else's mouth to be bitten off, he said. Mr Bougher added that such a bite could have been an ``involuntary, spontaneous reaction" to finding a tongue inside someone's mouth.
