I'm not really sure which one he was referring to here, cGorg. He does say "(suspect)" after the son's name. But it's not really clear which one died.

"There was a composit drawing made of 2 people of interest in the case. That drawing was so precise, that it was just like they took a picture, of the 2 suspect's. When I looked at the poster, I had a gut feeling I knew the 2 people, on the poster. It bothered me so much, I had to go back, and look at the drawing again. I looked at the eye's, and blam, it hit me. It was a picture of the father & son. The son (Suspect) used to work for a local nightclub. He would go up on the roof, during band break's, and watch the guy's and gal's, get it on in the parking lot. He took a bus driving job, for a local school, and got fired for pinching little boy's, in the a$$. I've said all I want to about the subject, or I'll have the FBI knocking at my door, wondering how I knew that. When the suspect died, I figured justice has been served."
I'm wondering if we couldn't go back through that Topix link and see what else this "Gary" had posted - it might give a clue to who he was. I still think the best bet would be to send it to LE though, as human said, they have the resources to find out who the poster was and question him in person.
That's a good idea....I read a little ways back but apparently not far enough to find the original quote. Might be a way to find out if Gary is legit.
