Thanks Pharmchick !!
Correcting myself here ... the timeline map shows that she DID in fact use a debit card to pay for her short cab trip within the downtown area. From what i can glean distance-wise, that trip should have been, what ... about $10.00+ I wonder what her bank account balance was at the time she disappeared.
Just before arriving at the shelter, she had used the bank machine for the second time that day. With those two withdrawals on the same day, I wonder how much cash she had on her when she got in the cab (iow, did she have gobs of cash on her to pay for a plane ticket?).
Also, the short time she spent at the shelter leads me to believe she maybe just went there to use the phone to call the cab.
