It could be a trafficking stamp. She may have been lured in by an older man looking to traffic young girls. POH may stand for Property Of and maybe the trafficker, if there is one, his name starts with an H. The S in this case might mean “sex” or “slave”, like a BDSM type thing. However there is no evidence that Jane Doe was SA’d before her death. She could have just died and someone dumped her out of panic or hoping someone would claim the body. That’s just a theory of mine.
Or it could just be a tattoo. Just a normal tattoo. Maybe the letters have some significance to her? Maybe a boyfriend’s initials, her own initials, a lost loved one, like an aunt, uncle, grandparent, sibling, etc? Maybe the letters have no meaning. The tattoo is very distinct.
I have a similar tattoo to this girl. Mine is homemade, obviously, since I’m only 16. Mine reads “с миром и любовью”, which is a Russian phrase meaning “with peace and love”. I have Russian heritage and my grandmother would write this in her birthday and Christmas cards she gave to me. She’s still alive but in bad health. Maybe it’s a foreign word or phrase? Someone suggested Hindi or Bengali letters.
To be honest I can see that. She looks very racially ambiguous to me. She looks more Latina in the composite but more Middle Eastern or South Asian in the PM photo. Maybe she was Indian/Bangladeshi and the letters meant something in Hindi or Bengali?
The same person suggested Cyrillic. I have nothing to go off of for her tattoo since there are no pictures of it available, but maybe it is Cyrillic. Again, I’m Russian-American so I know what Cyrillic looks like. But with letters that look similar to these they have no meaning in Russian, leading me to believe if this is in fact Cyrillic on her tattoo, she may have been from/have heritage in the Central Asian “stan” countries (Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, Turkmenistan). Really leaning towards the last three. Those countries use Cyrillic too, and especially did in 1989. Now they are kind of switching over to Latin or Arabic script.
