... when they found his body on the bottom the searchers were also unable to ditch his weights ... they were jammed in too tightly to allow the release mechanisms to function properly.
The problem with a lot of weight-integrated BCDs is that they were not designed with adequate capacity for cold-water diving. Add to that the habit of newer divers to overweight because they "can't get down", and you have some BCD designs out there that won't break away like they're supposed to.
Divers ... new divers in particular ... need to be aware of the design specifications of the BCD and not overstuff the weight pockets ... which is quite easy to do with soft weights.

An extra 2psi, if I may -
I recommend brick weights to everyone I see who uses an integrated BC - I have absolutely no idea from where this odd myth of "integrated = soft bags" came, but it seems all too pervasive. Soft bags can be used as doorstops, but little else.
(Integrated BCs forever, IMHO - sooooo much easier and more comfortable!)
As well, part of the OW training all the instructors with whom I've worked includes not only the dropping of weights and oral inflations, but
in-water donning & doffing; if you're in cold water and you can't get to your weights? Ditch the gear - you'll float like a cork.
If I may continue to be so opinionated (apologies semi- in advance), you must have some self-rescue contingencies tattooed to your brain; ESA, EBA, gear ditching, single-bearing navigation, etc. - if anything compromises your dive, it is up to
you, not your buddy or the boat or the Caost Guard, to get you to the surface &/or to the shore. (Barring severe physiological complications, of course - there are incapacitating events that complicate things.)
