Bone marrow or tooth pulp are common sources. Both are relatively protected, and thus less likely to have decomposed or been contaminated. Also mitochondrial DNA testing can be done on particularly degraded samples. Mitochondrial DNA isn’t as uniquely identifying as nuclear DNA, but there’s a lot more of it.
Most cells in the human body are nucleated, so you can get DNA from most of them. It’s just that the biggest cellular component of blood is not.
