The family of murdered Sydney dentist, Preethi Reddy, has spoken out about her tragic death. In a statement, her younger sister described the 32-year-old as a 'bright light' who was living her 'best life' before the attack. Her body was found in a suitcase, inside an abandoned car at Kingsford two days after her family reported her missing. Police are investigating whether her ex-boyfriend is responsible. He died when he deliberately drove his car into a moving truck after being questioned by detectives.
