The link may or may not load quickly because I suspect the site is overwhelmed as this news is just breaking. Sheikh Mohammed's eldest and owner of Zabeel Racing, Sheikh Rashid, died of a heart attack at 34. I'm assuming some sort of family history or a birth defect since he was so young. I'm not sure we'll get more clarification on this point, but I'm sure Bloodhorse will give us some sort of update soon.
