It just dawned on me that I remember this case from some TV Crime show about it.
I remember now how the perp made his 2 friends leave. Ugggg.
One article talks how he was meticulous with his yard in the years that followed. Makes me think he buried the boy somewhere close to where he lived near his mom before he had moved in with the dad.
That's the trouble LE has when people bury someone is you cant just go digging up tons of places. It would be good to interview people that lived near the Moms place to see if they knew of any good yards or lots that would be a candidate place.
