ABC News reporter Gary Shepard, who was savagely beaten by a robber at his remote home, was in fair condition yesterday as he recovered from surgery to repair his fractured skull.“He’s still groggy, but his vital signs are very stable and the prognosis for recovery is good,” said Ted Braun, spokesman at Santa Monica Hospital Medical Center. Shepard, 53, underwent surgery Tuesday night after being found severely beaten at his home in the Santa Monica Mountains above Malibu. His condition was upgraded from serious to fair early yesterday, Braun said. “He had some confusion and memory lapses in our emergency room yesterday,” and still displayed some symptoms yesterday, but doctors expect full recovery, the spokesman added. Authorities believe a lone male robber attacked Shepard after the newsman answered his front door, said Los Angeles County sheriff’s Detective William Soltis. Shepard has been an ABC correspondent based in L.A. since 1984.
