Secondly: Alan's other roommate and I located Tonya and Tad both, but we were too late for the service.
The Internet really wasn't all that much help. I got a list of Tonya Clarks from people.yahoo.com, and called about 10 of them (with the right middle initial) with no luck.
My friend called Kunsan Air Base in Korea (ouch!), and was told that Tad was now in Spangdahlem, Germany. I did manage to find an after-hours phone number on the Internet for the 52nd Fighter Wing Public Affairs. My friend called there (ouch! again), told them his story, and left his phone number.
Tad had just gotten back from the burial service in Washington State four hours prior, and called my friend.
