Not quite the same circumstances, but one of my wife's acquaintances was going through a divorce. She got a phone call one day asking if I wanted her husband's guns (I didn't know him), as she wanted them out of the house. I said I would take them - nothing very valuable or unusual however, a .22 pistol (Colt Woodsman) and a bolt-action 16 Ga shotgun. I told her I'd give them back to her husband if he wanted them, but I never heard anything more. I imagine that sort of thing happens a lot in divorces.
