A medical examiner has determined that a heart rhythm problem caused the death of a teenager who collapsed after completing a half-marathon in Virginia Beach.
The Virginian Pilot (http://bit.ly/1koIMUW ) reports that the Tidewater medical examiner's office found that 16-year-old Cameron Gallagher died of cardiac arrhythmia.
The Richmond teenager collapsed after crossing the finish line at the Shamrock half-marathon in March. She was taken to a hospital, where she died.
Gallagher's father, David Gallgher, tells WRIC-TV (http://bit.ly/1kVx9Vw ) that she competed on a swim team, ran with her family and played basketball as a child, and didn't have any symptoms of any heart conditions.
He says the family wants to have genetic testing done to see whether Cameron's siblings might have any conditions.
