I've read the various posts about HawkeyeNJ since his disappearance last year. While there is a good chance he is William Cashman, we can't be sure.
Best evidence:
1. Match of HawkeyeNJ's Memorial Day post to Cashman serving in the 187th Infantry/101st Airborne
2. Timing of no longer receiving posts from HawkeyeNJ with Sept. 11, 2001.
Conflicting evidence:
1. Ramsey NJ is far enough from North Bergen NJ so that the towns would not be used interchangeably
2. I believe Ramsey NJ is accurate in that Ramsey is 15 min from Paramus, NJ and West Nyack, NY. North Bergen could be 15-20 to Paramus, but would be about 45-50 min to W. Nyack.
While it is possible that Cashman could have moved from North Bergen to Ramsey, nothing in the articles I've read, say anything about a Ramsey, NJ residence.
HawkeyeNJ was a great contributor to AT. I looked forward to his posts. William Cashman was one of the heroes of Flight93. Maybe this is the same person, maybe not. Either way, we're talking about a good person with a great heart.
