text: My second reasion for going with the FACS is becaues it may be able to uncover crimes like if the dead persion was sad or happy when they die. Some family members may want to know that but will never know if they don't have the FACS. The FACS seem to be good on paintings so I was thinking that it may work on a dead body. Becaues if it works on Mona Lisa, then it should work on anything that dont use muscle ever or in the past like a dead body.
