I'd be very surprised if they DIDN'T give them each a No Contact order. At a minimum, the investigating officer would have told each of them that they are NOT to talk with anyone related to the investigation.

Obviously, OM is part of your W's investigation, and your W is part of the OM's investigation... so I do think that you should discuss this with your BN Cdr and ask him if you should send him the most recent phone log.
