Mom: Teen who collapsed in gym class died of heart attack

The mother of a 14-year-old Somerset County boy who collapsed and died during gym class at his high school earlier this month says her son died of a heart attack.
Tracy Warren says her son, Dyllan Burrell, had showed no signs of being ill before he collapsed May 8.
Warren says, "I guess God was ready for him, but I was not ready for him to go."
According to authorities, the Franklin High School freshman was playing lacrosse when he collapsed on the football field.
School staff performed CPR before he was taken to a hospital, where he was pronounced dead a short time later.
AP wire services helped contribute to this report.
