of interest, it seems that within 2-3 weeks of this there was other murder/suicide involving 2 more agents (will try to find that link)
Do a google on Derouchey and Suicide, I think it was the fourth or fifth hit.
Did you see that DeRouchey was an American Indian? Cheyenne, I believe. That's why the hits were Indian/Native American publications.
