Who authored the web site that would lead you to believe that he has "quite a track record?" Or have you independently confirmed all of the claims on the website?
Is there any evidence (other than his website) that this picture or any other information provided by Brian aided the police in any way?
Not bad! According to the website, it says:
"die mar 26, they missed them, bran you can find, trust your gift purvis henng ec"
It says the picture "may be about two missing boys," but I see the words "her" and "bra" in there that might indicate otherwise. There is also nothing in the drawing that would lead Brian to believe that it was about two boys, unless of course he drew it AFTER seeing a story of two missing boys named Purvis Parker and Quadrevion Henning on CNN, and then posted it to his website the day AFTER the CNN story came out.
It is extremely suspicious that he posted this drawing on 3/23/06 but claimed that he had drawn it a week earlier, while a story of the two missing boys appeared on CNN on 3/22/06 AND WAS APPARENTLY SENT TO HIM BY A FAN THAT SAME DAY (the day before he posted the drawing).
The drawing has a stamp on it that says "Mar 21 2006" as if that's somehow proof that the drawing was made before the boys disappeared (but oddly several days after he claims to have drawn it).
This is so silly it would be funny if people like Hardenbergh didn't believe everything they read.
