LINDEN, N.J. -- Four gunmen posing as flower-bearing mourners at a New York City gang member's funeral opened fire on about 100 people at a cemetery, wounding seven people, officials said.

At least seven other people were trampled in the panic that followed the gunfire around 3 p.m. at Rosedale Cemetery in this city just south of Newark, and were treated at hospitals for cuts and bruises.

A 20-year-old man who was among those shot was flown by helicopter to the trauma unit of University Hospital in Newark. The others' wounds were not considered life-threatening, hospital officials said.

Police Capt. Raymond Beckman said the funeral was for an Asian man he identified only as a member of a New York gang called Born to Kill.

About 100 people were attending the funeral when the gunmen fired, then fled, Beckman said. "As they walked by the casket with a bouquet of flowers, they dropped them and opened fire on the mourners," the captain said.

Three of the gunmen fired Uzi submachine guns, and the other used a shotgun, Beckman said.

The people attending the funeral were brought to the police station for questioning. Beckman said accounts differed on how the gunmen got away. He said police efforts were hindered because most of the mourners, who were Asian, speak little or no English.

The man flown to University Hospital was taken to the operating room, said nursing supervisor Dorothy Crews.
