I didn't make the post, I just shared it.
There is also some post going around of a little girl running in a marathon and they say it was the 8 yr old killed in the blast. The 8 yr old was a male!
Lots of crap on the net!
You shared it, and implied that you found it at least moderately credible. I question the rationality of anyone who doesn't automatically recognize the ridiculousness of "x person is actually y person" posts.
