One data point, which may help people determine risk levels of doing solo searches:
A former instructor of ours (and former friend of mine) was leading a group of divers (some reports say group of students) - he came up, his students/divers didnt. So he went back down to look for them. Students came up, he didn't. His body still has not been found.
