The bends didn’t seem to be a problem for the divers who brought her body to the surface. They did it in a minute and a half. His dive computer indicates it took him over twice that to reach the surface.
Depends on how long they were down, what other dives they’d done, etc. If they just got in, they could swim down, get her, and pop back up. If they had been down for a while and/or had been diving earlier, they could have been VERY sick and in utter agony from doing that. (You used to have to work dive tables to figure all of this out, now the dive computers handle it — although I prefer to work the tables, too, just to be safe.) Same applies to the husband. If he’d just started diving, there was no need for a safety stop. If he’d been down for a while or diving earlier, a safety stop may have been legit and in fact necessary.
PS From what I’ve read on this, I don’t think a safety stop was necessary, but can’t be sure.
