If you mean test it for DNA, then the answer is YES. Also the size of the print would be a determining factor.
You know, the big problem, I believe, was that there were the 3 items in the MH (hair,print,DNA) that some believe proved DW did it and some believed proved nothing. Some believed those items were planted. To accept this, you would have to beleive the SDPD (or certain members) are corrupt, that the DA might be corrupt. That is something very hard for people to accept. Especially if they live in SD.
