FYI, from TMZ:
The glove authorities found 2 miles from Nancy Guthrie’s home has been DNA tested in Florida, but there’s still another step before the DNA profile can be entered in the CODIS system ... sources with direct knowledge tell TMZ.
Under federal law, the FBI cannot use the CODIS system unless the item in question is tested in the state where it was found — in this case, Arizona. Our sources say the glove has already been sent back to Arizona. As for why the Pima County Sheriff decided to send the glove to Florida in the first place, knowing the glove would have to be re-tested in Arizona ... our sources have no idea.
The sheriff is clueless is the obvious answer, and probably correct.
