This pretty much matches with what I heard while I was up there, on VHF while it unfolded, and at the dock from someone who was involved in the recovery later. So I feel more confident about posting details as I have heard them, but please keep in mind that this is second-hand and I cannot vouch for accuracy.
Three divers on a private boat set out to dive the Cedarville, a large wreck that sits at 105 ft. The conditions were excellent (calm waters, 50ft. viz), but the water cold (~40F at depth). 18 minutes into the dive, buddy realized that Javens had a problem. I do not know if he was already unresponsive at that point just very soon thereafter. Buddy tried to bring Javens up to the surface, but his BCD did not have enough lift and he ditched his own weights (instead of Javens'). He lost grip of Javens and had an uncontrolled ascent, and was rushed to the nearest chamber. I'm not sure what the third diver was doing, but on the radio they mentioned that they didn't have anyone on board to go into the water for a rescue attempt.
Another boat with a rescue diver arrived at the scene within maybe fifteen minutes, and he was able to bring the unresponsive Javens up very quickly. The rescue diver reported an empty pony, but full tank on the back, a disconnected BCD inflator hose, and a non-functioning drysuit inflator on Javens. Javens did not show any signs of life, but was rushed to the next hospital where he was pronounced dead. RIP.
