To me this looks like a radiation and cyanide attack. Notice how she said pimples first? I would almost bet that they sprayed her with a a slight damp mist, which is why even nose was bleeding. The purple color is the blood vessels and capillaries being destroy until they turn black. Notice also the shedding of skin. She is in extreme pain, another sign of cyanide. Radiation is what causes the process to speed up and circulate through the blood. Seen the same thing with a relative at the VA.
