Probably a dissenting opinion, but here are my thoughts. Surivors/dependents fill out a CJMAB (Central Joint Mortuary Affairs Board) Form 1, "Disposition of Remains Election Statement Initial Notification of Partial Remains." Section 2 of this form asks the next of kin to decide between the following:
Option 1: In the event that further remains are identified, I would like to be notified and given the choice of accepting subsequent portions for disposition.
Option 2: In the event that further remains are identified, I do not want to be notified. I authorize the Army, Marine Corps, Air Force or Coast Guard to make appropriate disposition.
As you can imagine, many survivors don't want to be notified a month or a year later that an additional body part has been matched to their departed loved ones, and select option 2. To all of you who are shocked and horrified - what would you have the mortuary affairs folks do with the odd body part that is later matched to the deceased, when their next of kin have selected option two?
Naturally, cremation seems appropriate. The government has already been authorized to dispose of additional remains, so what's wrong with putting the cremains in a dumpster? The deceased have already been honored and buried, presumably with respect, so if the families don't want to be notified, and have instructed the government to determine disposition, I fail to see the cause for hysteric uproar. And yes, if a limb of mine turns up a year after I'm dead and gone, feel free to incinerate it and throw the ash/bone mix away.
Flame on.
