A jogger raped and bludgeoned by a gang running wild in Central Park remained in a coma Saturday while eight teen-agers awaited arraignment on charges of attempted murder.

The 28-year-old Wall Street investment banker, who was left for dead by her attackers Wednesday night, was in critical condition on life-support systems, said Metropolitan Hospital administrator Julio Aguirre.The woman's family, which arrived from Pennsylvania, kept a vigil at her bedside, Aguirre said. Doctors said the next few days were critical to her recovery from massive head and brain injuries.

By early Saturday, police had arrested eight suspects, ages 14 to 17, and charged them as adults with attempted murder, rape and assault.
