A few observations about the phone bill:
1) The phone was located in New Jersey in the 609 area code. Several local calls (calls listed without an area code) are in towns that were (and still are) in the 609 area code, e.g., calls on 11/17, 11/20 and 12/16 to Hightstown, NJ as well as others to Riverside, NJ on 11/23 and 12/14, as well as several others. Also, the number listed at the top of the bill is 609-888-1300 (now Hamilton Yamaha, looks like it a business number; maybe the local Bell Phone at the time?).
2) The bill implies that she lived (or stayed) in New Jersey between 11/17 and 12/16 based on the dates of the calls.
3) The bill appears to be missing pages (they are page 2 of two successive months' bills). Unfortunately, we don't know where she might have called on Thanksgiving, which would have been 11/26/1970.
4) It looks like she received a collect (?) call from Newark, NJ on 12/11/1970 in the evening (rate = 2).
According to the Daily News article on 5/14/1975, she was last known to have been working in NYC. According to the court transcript cited earlier in the thread, Carmichael and DeFreitas robbed a bank in New Jersey on 12/22/1970. How I wish the phone bill that covered the 22nd, five days after the last call we can see, which is to Levittown, PA on the night of 12/1970.
