Hello I'm new to the board but have been following the case for quite some time. I feel with the evidence provided that Hobs was the killer. My reasoning is for his past drug abuse & past physical & sexual abuse. You have the sexual abuse of his son as the igniter & I believe when Hobs finally caught up with his son he told his father that he was going to go to police about the abuse to avoid a beating. This of course explodes into Hobs killing all three boys because now the boys know about the abuse. He was the last one seen by eyewitness with the boys.
