I suspect that any DNA found would test out as having come from a cockroach - not very smart, hides in dark, damp, tight spaces, runs like Hell when you turn the lights on and can't drive worth crap but can survive a nuclear blast and not even think anything happened. When you catch it and step on it, it'll still twitch for hours. Its body can live for days without its head since it never really uses its brain at the best of times anyway. It's a useless creature that noone can understand why nature put on the face of this earth to begin with.
