Dear Linda,
I have no information on this incident other than what I have read on this site. I wish I could be of more help. As things unfold, please know that you have a supportive group of readers on this website and that we would be interested in any enlightenment you might, ultimately, be able to provide. You have my deepest sympathy on the loss of your friend(s).
Be well,
Ron Migdal
