State Police said Monday they are investigating the shooting of two people at the Shinnecock Indian reservation in Southampton.
As required by law, Southampton Hospital notified police at 12:45 a.m. Monday that two gunshot victims had walked in, state police said.
The victims said they were attending a memorial service at the reservation when a dispute escalated into gunfire, police said.
The injuries were not life-threatening, police said, but one victim was airlifted to Stony Brook University Hospital.
The victims were identified as local residents, but police did not release further details, saying they were seeking cooperation from the tribe.
Tribal spokeswoman Beverly Jensen said the two were not members of the Indian nation and that she does not know why they were at the reservation.
She said the shooting did not occur during a memorial service because there was no service that late at night.
"Tribal officials are working very closely with police to find out what happened," Jensen said. She said all that tribal officials know is what investigators know: "Two people were shot, probably shot here."
