Condolences to her family & friends. May her soul RIP.
Who led the dive, the man with the camera or the deceased woman? If he was the guide & leading the dive, then she would have followed him & wouldn't be separated. Photographer tends to stop, focus on an object, snap pictures & move on. If she led the dive, then he may have gotten distracted with snapping pictures, didn't follow her, she was not aware of him lagging behind & ending up with a separation.
It is both of their faults regardless of who's first or second. The guy with the camera needs to pay attention to buddy separation regardless of if he's taking photos. The deceased also didn't have the buddy awareness to stay with her buddy.
That isn't accurate as far as I remember. There is no jumpo where the Paso de Legarto is. The line simply turns left. I also don't remember what you have marked as jump 3. From my recollection you place a line in the cavern zone to the cave line (I tie into the cavern line as it turns and head straight to the cave line). Follow the cave line along past the left to paso de legarto and continue one until a gap that leads to the Cuzan Nah line. From there it seems correct. But I don't believe nav decision 2 and 3 are accurate unless things have changed.
It's possible your jump 3 is the gap I'm thinking of, but there's definitely no jump unless you go to paso de legarto.
