Not sure whether he had one at the start of the dive or not, but when found, he did not have any lights on him. At best, he did not have a back-up or a tank light and his primary wasn't secured.
Willing to engage in hypothetical discussion, if only to show the potential issues of doing so and the need to make informed decisions about processing information.
I have no information about lights - first-hand or second-hand - but there's probably a need to understand what could be a semantic issue:
- Did he have any lights "on him" when found?
- When found, did he have any lights with him that were on?
Did your source (or if applicable, your source's source) make clear which he/she meant?
I don't know the answer, but it's easy to see that if he did have a fully-charged, working light "on him" at the beginning of the dive... that the battery would quite likely be drained by the time they started a search at 11:30 or so. Certainly it would be drained when they found him at 3:30 in the morning. In the same vein, if he had a backup with him, but he died before the primary battery was drained he would not have ever turned on the backup on.
So when someone says "He didn't have any lights on him when found" do we know if they were specifically - and accurately - talking about whether he did not have a light when found, or if he did not have a light that was functioning when found? He may well have had a dead primary and a working, but never accessed secondary. Or he could have entered the water with no lights. Or he could have lost his light(s), causing the accident. Or he could have lost his light(s) in a panic due to the accident. Or the light could have fallen out of his hand after he died. Or a unicorn could have stolen his lights. In any of these scenarios it's easy to see how someone might say "when found, he did not have any lights on him." And we still have no idea what actually happened OR how to interpret the second-hand information.
I've personally seen this sort of "telephone game" thing happen in other incidents, where someone reports "a fact" in a way that gets unintentionally twisted by over/under-reading something into what was said. In one case a second-hand person observed "I heard that the victim did not have a reel when the body was recovered" which was widely spread as "the victim was stupidly diving without a reel" when in actuallity what happened was "the recovery team left the victim's reel in-place on the bottom when they brought the body up."
