Runners and neighbors of the teens charged with beating and raping a jogger in Central Park prayed for the comatose victim as doctors studied discouraging results of tests on her brain.

Prayer vigils were held Tuesday for the 28-year-old investment banker, who was ambushed by a gang of youths April 19, and a Department of Correction spokeswoman said two of the eight suspects had been attacked in jail by other inmates.Tenants of the a middle-income apartment complex where four of the eight suspects live held a noon prayer vigil Tuesday outside Metropolitan Hospital, where the victim is a patient.

Mayor Edward I. Koch convened another vigil at the hospital at 6:30 p.m. where a rabbi, a Catholic priest and an Episcopal priest offered prayers for the victim's recovery and for an end to violence and racial discord.

A crowd of 300 blacks, whites and Hispanics, many holding hands and with their heads bowed, stood in silence as the clergy spoke.

About 100 joggers ran from the hospital to the park near 102nd Street where the attack had taken place. They were joined by another 100 joggers. After observing a minute of silence, several runners spoke about safety.
