One cannot say that DNA will be transferred with absolute certainty. However, fingerprints have multiple sources of DNA, perhaps the principal one being cell-free nucleic acid, as Suzanna Ryan pointed out in an interesting article. DNA can be transferred to a plastic tube just by holding it.
In addition, there have been a few academic studies of simulated strangulation (which, one hopes, were less violent than the real thing), and DNA was transferred, in some but not every case. Link here. It has been some time since I read about this subject; therefore, my memory may be a little rusty. Guy Nathan Rutty has been perhaps the most active worker in this area.
Why is there no Knox DNA on her own lamp?
