Jesus Christ, didn't you just see I spoke with his father 10min ago?? He's not dead.
Read today that he liked had an arrhythmia called long QT syndrome which can happen in young athletes. Completely non-AAS related. That arrhythmia can suddenly become Ventricular Fibrillation, which can be deadly and/or cause a heart attack. We don't routinely do ECGs on athletes in the US but this kind of abnormality can be caught on ECG.
