THE BRONX - Classmates, teammates, friends and faculty gathered this afternoon on the football field at Truman High School to remember Isayah Muller, who was killed yesterday during an argument just after he had graduated from the high school.

Muller was remembered not only for leading the team to a Public School Athletic League championship last fall, but for his charismatic smile and cool demeanor on the field and in the school's hallways.
