Okay, I made an account to specifically post this. My qualifications are that I have been an EMT for 12 years and have two family members that do amateur MMA. I came across this story and looked at the black eye pictures I need to voice my objection from experience:
These black eyes, in no way to me, look genuine. One, in the height of punching any slight movement on the part of the intended victim or the individual throwing the punch can greatly change the impact spot. To be given two black eyes without other visible damage (in the same stage of healing) is almost unheard of. Imagine two successful punches to the eyes (opposite sides, so take in to consideration that two different angles of punch would be needed) without the person moving and getting hit and bruised in other areas of the face that easily split or bruise.
Second, with black eyes there is substantial amount of swelling more often than not. Neither eye looks swollen.
But let's assume that he connected two shots with the eyes and swelling has been minimal/non-existent (a stretch, but I will entertain it).
Neither under eye lid is discolored. Black eyes (non fictional make up ones) extend to the eye lid as well. Make up ones usually don't because of the movement of the eyelids and the smearing/make up in eye possibilities.
But the most important thing to notice is that neither eye is even remotely red nor any signs of broken capillaries. The vessels in our eyes are easily broken/irritated and take time to heal. I have NEVER seen a black eye from punch or true accident that did not also effect the whites of the eyes.
Now, sure, this could be a one in a million situation where all of these factors combined and he could have done something to her and then directly implicated himself as much as possible online, but in my experience the damage is lacking any of the normal signs except I saw a similar look from someone who had been slammed to a wall hard enough it blacked her eyes like that. I couldn't believe it. Not vouching or arguing if this injury is genuine or not.
