A 49-year-old Melbourne woman has pleaded guilty to stabbing her mother in the stomach because the elderly woman complained about the way her lamb chops were cooked. Thomastown woman Julie Smith pleaded guilty in the Victorian Supreme Court to stabbing her 70-year-old mother 48 times in the stomach with a butter knife. The court heard the mother, an invalid, who was confined to her bed most of the time, was unhappy because the lamb chops her daughter prepared for her were not cooked enough. The court heard Smith cooked the chops further for her mother before saying: "Here's your tea is it good enough for you?"The daughter then smashed the plate over her mother's head, before attacking her with the knife. Smith's lawyer told the court his client was terrified of her mother but had ended up being her full-time carer. He said she simply snapped under the weight of fear, stress and anxiety. The hearing continues.
