listen. >> what do you make of the credibility of tony zarelli's story?ht gee this is great. this is the first made member of the rg oed crime family that i'm aware of that spoke freely and openly with the fbi in detail about the hoffa disappearance. keep in mind, he was in jail on a racketeering conviction when mr. hoffa disappeared. when he got out, his father was still the boss. he was the underboss. i'm sure it would make sense if he asked what happened to jimmy hoffas. the individuals probably would have told tony zarelli exactly what happened. they wouldn't have lied to him. he was the son of the boss and would have been told the truth. i think he is now relaying what he was told what he believes to be true. and i believe it's credible. >> do you think it is the most credible tip the fbi has had since hoffa disappeared in. >> yes, i would agree with that. >> reporter: now, the part of this, jake, that doesn't sit well with john anthony is the fact that he knew hoffa and he said that there's no way that they would have buried him alive and that he wo

he's tony zarelli and he is very well-connected. he was in prison when jimmy hoffa disappeared. when he got out, he talked with one of his buddies who told him what really happened to hoffa, that he was allegedly buried back here, knocked out cold with a shovel and then buried alive under a concrete slab on this property. could this be jimmy hoffa's grave? the fbi once again digging for answers, uprooting waist-high grass and weeds on private property in suburban detroit. >> why do we care? i don't know. we do. >> reporter: this time the tip is more credible than most. it comes from tony zarilli, a retired mob boss who himself did time. sources say his dad used to run the show in the motor city. >> he would have known, if anybody would have known, exactly what happened to mr. hoffa. >> reporter: when he got out of prison in 2008, tony jackaloni told him about hoffa's fate. after he was lured to a restaurant, he was taken to this property, killed and buried. >> what happened to hoffa was very simple. he got picked up over there, he was buried where i say he's buried. >> reporter:
