The one that went missing in 1995? Yeah, doubtful it's the same person. The tattoo seems recent (if it can be googled), the age is off, and coroner describes her as hispanic.
I have no idea why someone would carry two body sprays (and nothing else) in the backpack, but it does not sound like something a homeless person would do. I'd suspect a hooker, but size 16 petite pants are not exactly hooker geometry ... (but what do I know?)
