There's no such field as forensic virology. If you try to Google "forensic virologist," it will automatically correct to "forensic serologist." A virologist, without more, has absolutely no relevant expertise on the issue of whether the outbreak was due to a lab leak or came directly to the wet market from a natural source.

A virologist who is also a geneticist may have relevant expertise on whether the viral genetics indicate that the existence of the virus is natural or artificial, given a sufficient knowledge of extant viruses known to be naturally occurring. However, an engineered virus could have come from somewhere other than the WIV; or alternatively, a naturally occurring virus being studied at the WIV could have leaked. The question of whether the virus is naturally occurring is orthogonal to the question of whether it leaked from the WIV.
