I find it interesting that Doolittle went missing only 2 days before the UID was found, recently dead, in Las Vegas. Her car was found in Charlotte, which itself has a Greyhound bus station (although, as carbuff said before, there seems to have been a lot of bus stops then so this could just be a coincidence). Same hair color (brown) and length. Eyes are brown vs. hazel, which could have changed post-mortem or been evaluated differently by coroner, IMO. There are some things which make me not 100% sure, e.g. the fractured arm and pacemaker. The scar, I'm divided on; Florence had surgery on her 4th and 5th lumbar vertebrae, which is one of the most common spots for herniated disks, and it's possible that the scar on Doe could be a hernia repair scar as someone said earlier? I initially thought that the scar had to have been on the back because a herniated disk is in the spine area, but I saw this while researching:
"Surgical options include microdiscectomy using small surgical instruments and open surgical repair (
either from a posterior or anterior approach)."
Could it have an anterior approach surgery, in which the problem was fixed from the front? Based on the definition of anterior and some research, that's what I believe the anterior approach is. I'm not an expert on surgical procedures, of course, so if you have knowledge of this, feel free to say your approach on the matter.
I'm considering submitting Florence Doolittle as a potential match to authorities; the timeline and scar really make me think it could be her.
