I was asked this at a different board:

On the show back in the late 80s, there was a case about 2 or 3 boys who went into the woods to just play around. They might have been on 3-4 wheelers or just walking. Not sure. Anyways, someone shot these innocent boys for no reason at all. It was assumed they had accidentally stumbled upon something they weren't supposed to see and this is why they were murdered. It was unsolved and there were no leads which is why it appeared on the show.

Do you remember this case? I've looked for it sporadically over the years but don't know enough about it(names of victims, location,etc.) to find it.

He says it's not the Signal Mountain Murders.

The details don't match, but is it possibly Don Henry and Kevin Ives?

Can the OP provide any additional details? Approximate ages or anything from the reenactment?

Yeah it has to be the railroad track murders in Arkansas they were not on ATvs that was the signal mt murders as pointed out. The boys were out spotlight hunting which is illegal and they did allegedly stumble across a massive drug deal via airplane landing strip somewhere near the tracks. I don't know if that is true or not but that's the rumor. And there was allegedly a cover up by the DA featured in the segment.

Linda Ives is still fighting for justice. When she said, "whatever it takes"....she was not kidding. Frightening example of layered corruption.

I am dying to see this episode again. It's probably been since the late 1990s since I've seen it. It's not on any of my DVDs.

I do not believe it was a conspiracy on the state or federal level. But I do believe the boys were murdered for seeing too much, most likely from local organized crime (possibly LE). Reminds me of the other kid from Mississippi, where his death was ruled a suicide.

I grew up in rural East Texas, not too far from Arkansas. There is and has always been a general consensus not to question the nobility of law enforcement. In many ways, in this good ole boy society, if you stay out of their way, they stay out of yours.

Who smokes fifty joints? And why did people initially accept that as a normal amount of marijuana for one evening, two teenage boys?
