The attack followed the accidental death of Gavin Cato, a black child who was hit by a car in the entourage of the Lubavitcher leader.

If today's announcement raised the hopes of Mr. Rosenbaum's relatives and the Lubavitcher leaders, a trial could yet disappoint them.

Mr. Fugazy confirmed that the Lubavitcher leaders spoke of getting a court order to have the parade canceled.

"Some denominations see themselves as God's policemen," a Lubavitcher leader says.

All that combined to leave some major Jewish organizations at a loss over how to respond to the violence, and some say privately that Lubavitcher leaders initially rebuffed their offers of support.

The attack followed an accident in which a black child was killed when hit by a car in the entourage of the Lubavitcher leader.

Last spring, Mr. LaBorde wrote a letter complaining about the calls and quickly received a letter from the Lubavitcher leader, Rabbi Menachem M. Schneerson.

Though her son, Alexander, said, "I have no idea why she did this," Lubavitcher leaders immediately said it was a suicide brought on by the violence.

It is named for the wife of the late Lubavitcher leader, Rebbe Menachem M. Schneerson.

On the march route, the protesters stopped at the house of the Lubavitcher leader, Rabbi Menachem M. Schneerson, at 1304 President Street, where speeches were delivered.
