A 16-year-old was stabbed multiple times in the chest and is in critical condition. An 17-year-old suffered a broken arm during the melee.
Police are searching for multiple suspects from different schools. Video on social media which clearly shows who was involved is being used as part of the investigation.
"We believe this was a targeted incident. We do have persons of interest that we're looking for," said Det. Lt. Stephen Fitzpatrick of the Nassau County Police Homicide Squad.
"You know you gotta watch more," said Oceanside High School parent Anna Vargas. "My daughter going to high school. So you gotta watch more, where they're going, who's their friends."
Police say all the witnesses are cooperating. They are all students.
