What about Maria Kissh?<quoted text>
The area code is meaningless unless you know if it was a land-line vs cell phone.
Iirc, no one in this case was living in Fort Lauderdale during the time in question, but as cell phone numbers are portable, I suspect it might belong to Amy. Also iirc, she had worked on a cruise ship prior to meeting Casey, and it was berthed in Fort Lauderdale.
She lived somewhere else, as I recall.
