Thanks for the photo! It's definitely the best res i've seen so far!
Looking at it, i noticed a red spot on the right knee... a blood stain? There's also what it seems to be a scar on the right eyebrow tail.
Another thing i noticed is how long the hair is. The way it's lying on the ground and the angle of the head, i believe this person was hung by the waist and was most likely passed out or dead.
As to the streak across the face, i'm really convinced it's a strand of hair. It matches in color and texture.
MOO JMO
I also noticed the length of the hair! It looks comparable to my length, which is long enough to put in my pockets...but this person looks long-limbed and the hair may only have fallen mid-back for all we can tell!
I don't see any evidence this person experienced anything violent so I can't say for sure whether or not I believe they're alive or dead -- none of us can make that judgment for sure based on this picture alone. I will say I've seen photos of living people who are looking away from the camera with their eyes partially obscured and it gives me the heebie-jeebies like this picture. We don't like it when the pupil is obscured, I think it messes with our instincts.
I rotated the picture and it was somehow even creepier...fair warning for those who haven't done that yet. I did, however, realize how far closed the eyes are. A person upside down should have their eyelids fall open wider. It seems like this person may have had their eyes closed and they fell partially open. In which case, they weren't holding their eyes closed...
Or, Alcala could have caught the subject mid-blink and we're all overthinking their expression. Doing a cursory Google image search of mid-blink pictures, the expression certainly could match those (see: the Elon Musk picture).
I still can't determine the sex of this person. The width of the neck reads male, but the body/facial hair reads female to me, especially focusing on the sideburn and chin line. I'm not sure this person was so androgynous in other situations (it may just be this photo) so I don't think anyone searching for a person-match should limit themselves when looking.
I wonder if any other pictures were taken. Lots of Alcala's subjects had multiple photos taken.
The only thing we can really determine from this photo is that it's a head scratcher.
