I'm afraid I'm losing sympathy for the husband. Initially, I didn't want to suspect him just because they were divorcing. But knowing that she felt she had to leave town while he was served has changed that, as has seeing how long he has made the 21-year-old boy - and they are boys at that age - handle the shock publicly.
Beyond the initial shock, where the husband might get a pass for being distraught, there's no reason to me that you would let your 21-year-old son, whose shock must surely be greater than yours, and who is far less equipped emotionally just in terms of age, to be your "media spokesperson."
I can't imagine putting my son in that position. I shows, IMO, that this father is very profoundly narcissistic and thinks only of his own needs. He also seems to be concerned that if he speaks to media, he might reveal something he doesn't want to reveal. I also can't recall seeing another innocent spouse who has done so little to handle his own media relations, to plead for return of his wife, the mother of his two small daughters, and then force his son to do that work.
CPS needs to look at this situation.
