I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
I'm not a DNA expert, but I know that half the 23 chromosomes in a person''s nuclear DNA come from one parent and half from the other parent, so part of the father's DNA would have to be present in the child.
Mitochondrial DNA (which is a different substance entirely, a circular structure present in the cell's mitochondria, whereas nuclear DNA is a double helix present in the cell nucleus) is passed from mother to child without recombining, so only the mother's mitochondrial DNA is present in the child. We test for mitochondrial DNA when nuclear DNA isn't available, like when we only have cut hair or fingernails or old bone to work with.

I'm afraid I don't know enough about how 3-D printing works to be able to answer. I can guess that it might be handy for reconstructing items such as shoeprints and tire tracks from photos or scans. Other than that I don't see where making a copy of something would necessarily affect a crime. And as far as I know they haven't reached the point of replicating on a cellular level such as DNA.

As far as I know since they would all be the same type of cells, they could not be separated.

Sorry I went to the link but it just loaded forever and I coudn't view the picture.
UPDATE: Hey on a whim I tried the link again and could see the picture. Unfortunately I still couldn't make a guess as to what the pile is. Though in my opinion it looks too light-colored to be a decomposing animal.
