i watched the documentary a while back about this case, it was harrowing to say the least, and i still don't know, and i am sure many others involved in the case aren't 100 percent sure of her guilt.
She was convicted based on the evidence of the guys who by their own admission actually committed the crime, but who avoided the death penalty by putting someone else in the frame
that is correct the two men got a plea bargain but she is the one with the death sentence, as i said very harrowing, and indeed strange that she copped the lot.
