A woman who was severely beaten and raped in Central Park by a gang of youths has shown signs of emerging from a coma, and gave a "high five" sign for a hospital worker, doctors said.

The 28-year-old woman remained in a coma Monday and physicians were not optimistic about her chances for a full recovery, but she has squeezed hands, raised her eyebrows, smiled at jokes and nodded vigorously, said Dr. Robert S. Kurtz.The victim, an investment banker, was jumped by the gang April 19 as she jogged through an isolated section of Central Park on her nightly run. Six teen-agers have been indicted on charges of attempted murder, rape, sodomy and assault.
