A member of the Ramapough Mountain Indians who was shot on April 1 during a confrontation with New Jersey State Park Police died yesterday, the tribe's chief said.

Emil Mann, 45, of Monroe, N.Y., was shot in the chest and leg after the park police interrupted his birthday party at a popular picnic spot in the woods in Mahwah, N.J. He was at Hackensack University Medical Center until he died yesterday, shortly after noon.

The New Jersey Department of Environmental Protection, which oversees the Park Police, has asked the state attorney general to review the shooting to determine whether the department's rules were followed. The Bergen County prosecutor's office is conducting the criminal investigation.

The Environmental Protection Department has put the four officers involved in the confrontation on paid leave, including Chad Walder, the officer who is alleged to have fired the shots.

The officers are based at Ringwood State Park, near the picnic spot, known locally as the German house, which is on a rough trail. Police Chief James N. Batelli of Mahwah said the site of the shooting was apparently owned by Bergen County.

The tribe members visit it on all-terrain vehicles, Chief Batelli said, and the park police were looking for violators of state park rules prohibiting the vehicles' use. The members have questioned the use of deadly force and have said the police could have been outside their jurisdiction.

Tribe members said Mr. Mann was unarmed and trying to break up a fight between his cousin, Otis Mann, and a park officer.

After meeting with the prosecutor last week, the chief of the Ramapoughs, Anthony Van Dunk, said, "We're going to find out what the truth is." He added, "We have to find some level of security for our people, who justly are leery of authority."

The Ramapoughs are economically strapped and very rural, which sets them apart from most of the residents of wealthy Bergen County.

Tribe members said they considered Mr. Mann's shooting the latest assault upon their community, which has been engaged in a prolonged battle with Ford Motor Company over the dumping of paint sludge in the area. Ford's Mahwah plant closed in 1980, and the area was declared clean in 1994, but it has required three or four additional cleanups. Residents have attributed numerous health problems to the pollution.

Catherine Fantuzzi, an assistant Bergen County prosecutor, said that in the confrontation, Emil Mann was charged with aggravated assault on a police officer, two counts of trying to disarm a police officer, hindering apprehension and obstruction of justice. His cousin, Otis Mann, was charged with aggravated assault, resisting arrest and lesser charges. The prosecutor's office offered no further details.

Agnes Mann, a distant cousin of Emil Mann, said she was told that he was holding his arms up and asking, "What did I do?" when he was shot. "They had no business shooting anybody, no reason for doing that," she said.

A telephone call to Emil Mann's home yesterday evening was not answered.

Chief Batelli said the tribe should discuss the confrontation at length with the police, to address matters like why it happened and why the officers were in their area, "imposing certain laws on them."

New York and New Jersey recognize the Ramapoughs as a tribe, but the tribe has failed to obtain federal recognition. It has about 5,000 members.
