Exhaust fumes link to baby SA crash death A BABY in Adelaide has died in a low-speed car crash that police have linked to leaking exhaust fumes. The eight-month-old boy, a seven-year-old girl and a 33-year-old woman were all found unconscious in their station wagon after it slowed and clipped a tree, then a parked car, in Hilton on Friday night. Superintendent Bob Fauser says it appears they were overcome by carbon monoxide poisoning. "The indications are that they were overcome by the fumes and were unconscious before the impact occurred," he told reporters on Saturday. Investigators found significant wear to the exhaust and sealing on the car, causing fumes to drift into the cabin, he said. The family had been returning from dropping someone off at the airport, he said. The baby could not be revived while the woman and girl are recovering in hospital. "It's a terribly tragic set of circumstances," Supintendent Fauser said. I cannot begin to understand the trauma that the family must be going through.
