About three dozen people have marched through the Brooklyn neighborhood of Crown Heights following a memorial service marking the 25th anniversary of one of New York City's darkest chapters.

The 1991 race riot in the Crown Heights neighborhood started after Gavin Cato, a 7-year-old black boy, was hit and killed by a car in a rabbi's motorcade. Hours later, a Jewish doctoral student, Yankel Rosenbaum, was stabbed to death. Four days of violence followed.

The neighborhood is holding a series of anniversary events Sunday as part of "One Crown Heights." One of the events, a festival, has been criticized by Rosenbaum's family as being insensitive and trivializing what happened.

Cato's father, Carmel, said the neighborhood has become more accepting in the last two decades. He said he's disappointed Rosenbaum's brother didn't attend the event.
