thumbprints and signatures. except for the s in hawks where jackie signed. both times the letter is written in by someone else. why would jackie forget the s on her own name? was it a mistake? or was it a message that she hadn t signed that document willingly? there was no way to know. and then, in response to all that tv coverage the couple s silver honda crv with arizona plates is also missing. a tip that would change the direction of the case. we get a telephone call from an american citizen in mexico, and this person calls up and says i m looking at the vehicle right now. it s parked in a driveway in mexico. at that point that was the biggest break you got? absolutely. december 16th, 2004. a month and a day after tom and jackie were last seen, detective byington headed to mexico, hoping to find not only their car, but some answers, and maybe them. i m thinking tom and jackie hawks are hiding out in mexico.
