Counselors are on hand at the Philadelphia school attended by a teen who collapsed and died during a charity race.

The 19-year-old man collapsed Sunday during an organ donation awareness charity run. He was transported to a hospital where he was pronounced dead. Authorities did not immediately release his name, but classmates identified him as Alvin Way.

Officials say he was a senior at Furness High School in Philadelphia. He was at the race with students and faculty from the school.

School officials say a letter will be sent home to parents explaining what happened. The cause of death is unknown and an autospy is pending.
