911 call reveals Kyle Busch was ‘coughing up some blood’ at GM test center day before death.

An emergency medical service request was dispatched to the General Motors Charlotte Technical Center in Concord, North Carolina, on Wednesday around 5:30 p.m. ET, following reports that Kyle Busch was experiencing respiratory distress.

During the emergency call, which TMZ later acquired, an anonymous man informed the 911 dispatcher that Mr. Busch was exhibiting signs of dyspnea, elevated body temperature, faintness, and hemoptysis (coughing up a small amount of blood).
