reporter: in addition, detective salm would routinely log in to check on the whereabouts of peter and paul s trucks. and on the morning of thanksgiving day, more than four months after the bombing, salm turned on his computer to find the gps tracker on paul moore s truck. it had gone dead. we had no signal whatsoever. and this is also the type of gps that you could call. you know, just like calling on a cell phone. and wake it up. because they go to sleep when they re not moving. and where are you? we couldn t get a response from it. reporter: the device may have just died or been found, so salm got into his car with his partner, drove to paul s house to see if the truck was there. we got to his house. i look in the kitchen window and he s staring at me. okay. reporter: hoping paul hadn t recognized him, detective salm hit the road. as we re leaving town i look in the rearview mirror and there he is following us in his truck. he pulls in behind us. i speed up. he speeds up.
i think, like, probably 90% paul. but david and susan couldn t really give a reason why paul would want to kill roberto other than they felt paul just had the kind of personality to do something like that, while pete didn t. so you don t think peter is capable of actually developing a very sophisticated device to create an explosion? i am doubtful of it. i don t know him that well. that well. but i really wouldn t think he could. okay. and i also think he doesn t have the moxie to do something like that. what do you mean, the moxie? just the the meanness. the meanness? yeah. reporter: but peter had actually threatened roberto, wanted to fight him. and as far as anybody knew, paul had never done anything like that. nevertheless, based on this new information from david and susan moore, detectives asked paul to come in for another meeting. which he did quite willingly.
a locker-sized electrical box used to turn on a high-voltage irrigation pump had apparently shorted out and exploded. with such intensity metal fragments blew out the windows and covered the passenger side of roberto s new ford f-250. a miracle little fabian wasn t killed, too. translator: we received a phone call that something had happened. reporter: roberto s wife fabiola. translator: it was when we received the call from the police department and they said they had fabian and fabian was okay but they couldn t tell us what happened to roberto. we thought he was in the hospital. reporter: and you didn t know what happened to him? translator: we didn t know what had happened. we called the hospital and the hospital didn t know anything about what had happened. about an hour, hour and a half later, they arrived with fabian. my mom asked roberto where was my dad. and my brother just started screaming that he was dead. what was it like to see fabian in that situation?
ironic, perhaps, but for all his bluster, pete has never been in arrested, never been in trouble with the law, runs his own business, has been a good father, and over the years has taken in wayward teens to give them a better start. kids like nick. in other foster homes they do it for the money. pete didn t ask for any money in return. he fed me. clothed me. he gave me a car to drive. and now i look at pete like a dad. and anybody that has anything bad to say about pete never really took the time to get to know him because he is a good, loving person with a huge heart. we need more petes in this world. reporter: so why were the cops so focused on pete to begin with? well, as pete tells it his cousin paul planned the whole thing. set out to frame him. first by lying to him, telling him that roberto, or robert as pete calls him, was out to steal his birth right.
detective turned the tables a little and suggested maybe it was he, paul, who was jealous of roberto. i didn t hate robert. okay. did you not like him? i didn t like the fact that he would cop an attitude with me. just over something stupid, you know, and little. reporter: detective salm pressed paul about his past. you ve got several incidents here i have a criminal record. you ve been involved in some bad stuff. okay? you cut phone wires. i tried to help you guys out through this whole thing. you re going to start to cop an attitude i m not copping attitude with you, but i m having trouble with some of the stuff you re saying. i know my word doesn t mean anything. i was a felon, a drug addict. everybody knows about it. i put up with a lot of [ bleep ]. so this must have put a whole different complexion on paul.
