timer55 and other passwords used by casey in the phone calls

what could these passwords mean?

Timer55 as a phone number using the florida code.

Sean Farrell
Foxhall Apts
1832 Foxhall Circle
Kissimmee

The same person with the same number has another address:

SARF (his initials presumably)
204 Nth Vernon Ave

It's interesting because it could have come up anywhere in Florida and yet Kissimmee isn't too far away.

I will take a look when I get home from work but I'm almost positive there is a Sean Farrell involved and at one time I remember questioning if that is where she made up the name Raquel Farrell... will let you know what I find unless someone finds it first...
