On a recent visit to the 9/11 Memorial site, I noticed a new category had been added: February 26, 1993. I have to confess, I wasn't aware of the official casualty numbers from back then so I took a look at the victims - there were only 6. Of these 6 only 3 have a picture to their name.
The first victim I looked at was Stephen Knapp. I was drawn to his photo as it reminded me of the type we saw after 9/11. Not great quality, but also because the shadowing on his face seemed to contradict the light on the rest of his body.

Curious, I searched for more images and found an uncropped version at an online newspaper site:

Our friends at Voices of September 11 had a better version of this: It's also worth reading the tributes on here. They have a familiar ring to them.

Not for the first time one has to ask, "is this the sort of photograph that a family would hand to a news company to remember their loved one?" Furthermore, we know from this version that the previous version has been altered. The contrast/brightness has been adjusted and they have tried to make the photograph even more damaged and creased! The lighter version also reveals a strange white line under his beard - a sign of a cut and paste?

On the darker version we have a time stamp. This appears to be 07 11 86 or in US parlance 11th July 1986. I'm not sure why the "11" has faded - perhaps it was added for authenticity - and I can't find out when time stamps of this type first appeared in cameras, but 1986 seems plausible? My Canon EOS1 had them in 1989.
A further search revealed one more photo at the same online newspaper as the previous image:

Once again we have the "ripped/worn" edge of the photograph - though quite why someone would rip the photo in half when it is clear that his wife/partner are next to him is another matter! Additionally, it looks to me that the watch has been added. Same with the glasses to his chest - suspended in mid air with no visible means of support!
I was also drawn to the eyes as they looked strange, so I zoomed in and took this screenshot in Photoshop.

The eyes have definitely been tampered with. Why?
So, were the victims of 1993 genuine or fake?
