A graduate student who was severely injured in a chimpanzee attack in South Africa will be transferred to St. Louis University Hospital in the next week, Andrew Oberle, 26, of St. Louis, was leading a tour at an animal sanctuary in late June when he was pulled under a fence by two chimps. The chimps dragged Oberle about a half-mile during the attack. The manager of the sanctuary, South African conservationist Eugene Cussons, said it was the first such attack since it opened in 2006.
