My cousin just recently passed an he was said to have been sitting at the kitchen table and collapsed outta there chair onto the floor...blood came outta his mouth...we are waiting for results on the Artopsy...How long will it take to get these results?? He did suffer from high bloodpresure....overweight...and Epeleptic...but hasn't had a seizure in quite some time....could he have had a clogged lung?? He was only 51...He stopped taking his blood pressure pills said he feels fine and was once on dilatin for his seisures... but has not been on thos for a long time...maybe 5yrs now...Can you predict what could have been his cause of death???
