92-year-old Clara Tang on trial for murdering her 98-year-old husband in Australia

Clara Tang is charged with stabbing and bludgeoning her wealthy husband to death in their home in Sydney, Australia last year, the Sun-Herald reported.

When cops found her, they say Tang was soaked in blood after stabbing Ching Yung Tang twice in the stomach and bashing in his head.

She has pleaded not guilty due to mental illness. Her lawyers say she suffers from dementia and had feared her husband was trying to poison her.
