Heavy D 911 Call Recording Online
One of the first questions the dispatcher asks ... is D breathing? The caller -- who's so freaked out she can't stop screaming -- says he is.
Moments later, everything unravels ... as the caller shouts that the rapper has stopped breathing, and people on the scene then scramble to perform CPR.
An ambulance arrived shortly thereafter ... but it was too late. Heavy D was pronounced dead at the hospital an hour later. Listen here.
