One of the teens was identified as 16-year-old Sal DiNubile. He was a junior at St. Joe’s Prep and was on the hockey team. The other teen was identified as 16-year-old Caleer Miller.

Caleer was a junior at Mastery Charter Schools.

“Although he’d only been a Thomas student for just one month, he was starting to make friends and was very engaged in class. He also worked in the neighborhood and was active in his church and the YMCA. As we cope with the loss, we are offering counseling and support to students and staff. Our thoughts and prayers are with Caleer’s family,” the school said in a statement.

Police say the shooting stemmed from an argument from two groups of kids who were known to each other. Police say a gunman shot Sal and Caleer during the argument.

“I heard the shots from my house and I ran out and seen Sal lying on the pavement, he’s my best friend. And I just tried to do what I could, that was really it. The cops came, it was sad, it was really bad.
