Yeah, the understanding of biology to go from DNA to full body reconstruction is very far away. What they might be thinking of doing is creating a database of face and matching DNA. Then when unknown DNA is queried it probably finds the most similar sequences and then blends some of the most similar faces together.
I was imagining that they were going to acquire a large dataset of DNA sequences paired with photos of the patient and then train a neural network to predict one from the other. I don't think that would be particularly successful either (you would need a tremendous amount of data and DNA sequencing is expensive), but it would be interesting to see the results.
It wouldn't need to hold up in court. You already have the DNA so once you identify your suspect you can DNA test them to see if it's them and normal processes continue.
This is for cases when all you have is DNA that is not in the database to help you track that person down.
Basically like when they do a sketch based on a witness's memory except using DNA.
