She has an enlarged heart. It was diagnosed just recently though, but I don't think there is anything that could make that occurrence happen.....
They had a heart attack gun in the 70's. This country has a history of getting rid of "trouble makers" And she's been very outspoken about what happened to her dad, to the point where she confronted Pres. Obama about it when he done that town hall hosted by Jemele Hill.
Same way Darren Seals got "killed" in Ferguson after exposing all those BLM frauds.
But in the end, she could've just had a heart attack from stress, grief and being overweight.
