I've had the theory for quite a while that KC may have been involved in or been around an idenity theft ring. Florida, like California, is a prime location for false/stolen idenity info due to influx of illegals. Car dealerships are a prime location for obtaining this info, since they can access credit info, get necessary info from potential buyers, etc. Many of these idenity thieves start very young, with their first objective being false ID's to get served in bars, liquor stores, etc. Some go on to use the false id's or sell them to others. Some start once they realize they have access to info needed to create stolen idenities. I still think one reason we have not seen certain witness interviews, etc., is because LE has an ongoing investigation into something like this, that originated with info they obtained from some witnesses/evidence in this case....maybe even the license/ card/id that the officer snatched 7/15 or 7/16 from KC's wallet that was behind her DL (mentioned in CA or LA's interview and not heard about since- CA took the $, then LE saw something behind the DL and snatched it before CA or LA saw what it was).
For those who think this id theft stuff is farfetched- it's not...my son had his idenity stolen while in college in California over 10 yrs ago. He didn't even know until he decided to stay in Calif and applied for a Calif license to replace Maryland one. Was told that he already had one and that he lived in northern Calif, not L.A.!! By the time he got that straight, there were several more IDs out their with his name, dob, ss#, etc. thoughout Calif and Nevada, etc., including traffic violations, tickets, defaulted credit cards etc. There are STILL versions of him that show up every once in a while, and he has to constantly be on guard and check all his records constantly, to make sure some bozo in Texas or Oregon hasn't gotten a FTA warrant or anything else illegally in his name!
ETA- As near as LE could figure- his info was hacked from a college database!
