From the wikileaks 9/11 pager intercepts. What I did was, I recognized
that some pager messages were truncated, so searching for matches in
what appeared to be the pager ID number would complete the message.
This is from a pager with the number 005129647.

and I WILL be coming home tonight. I love you, xoxo, CB
