In the same city district as the wet market that was visited by a number of the first cases, there is a Chinese laboratory that does research on bat coronaviruses, and that has had accidents and international criticism on its safety in the past. It is hard to provide evidence, but the accusation is that it somehow originated there. Scientists seem to agree that it isn't an engineered virus, but that doesn't mean it isn't a wild virus first transmitted from bats to humans in that lab.
