GRETA VAN SUSTEREN, HOST:  Tonight, the FBI (search) says it has received at least two dozen tips in the bizarre death of a pizza delivery man who died when a bomb locked around his neck exploded.

Brian Wells' death first made headlines back in August.  And, just this week, the FBI released portions of a mysterious letter found in Wells' car seeking the public's help in cracking the case.

Joining us now from Phoenix is the brother of Brian Wells (search), John Wells.

Welcome, John.

JOHN WELLS, MURDER VICTIM'S BROTHER:  Hi, Greta.

VAN SUSTEREN:  John, why hasn't this case been solved?

WELLS:  I don't know.  But I'd like to help the FBI any way I can and let them know -- let the nation know of the $50,000 reward.

VAN SUSTEREN:  John...

WELLS:  Yes?

VAN SUSTEREN:  John, your brother, Brian, was -- at least the facts, as we understand it, went into -- was a pizza delivery man, went to deliver some pizzas, somehow ended up at a bank, committing a bank robbery.  The police then nabbed him a short while later.  He gets out of the car, and he's got this bomb wrapped around his neck and his collar, and he's got some notes in his car that were just released, and the bomb explodes.  Who wrote these notes?

WELLS:  I don't know who wrote the notes.  The FBI doesn't know who wrote the notes.  I would like the FBI to release all the notes so somebody out there who knows who wrote the notes or knows somebody who did would turn them in.

VAN SUSTEREN:  Any idea who would put this bomb collar around your brother's neck?

WELLS:  I have no idea who would do it.  I know there's a man in town who is -- who is in another -- who's been involved in two other murders and he's still on the streets.

VAN SUSTEREN:  Are you satisfied the FBI and the local police are doing everything they can to solve the mystery surrounding your brother's death?

WELLS:  I'm not satisfied at all in the investigation when the investigators continue to slander my brother.  My brother was not involved in this in any way.

VAN SUSTEREN:  And when you say slander, are you suggesting that -- I mean are -- that they are putting out there in some form that your brother robbed the bank...

WELLS:  Every...

VAN SUSTEREN:  ... and that he committed suicide with this?  Is that the slander?

WELLS:  Every -- no, the slander is every time that they say he might have been a willing participant when they know he wasn't a willing participant.  That note is further proof that he wasn't a willing participant.  He was doing what he thought he had to do to save his life...

VAN SUSTEREN:  Why do you think that the...

WELLS:  ... and...

VAN SUSTEREN:  Why do you think the FBI may have some -- say that they have some suspicion he's a willing participant?  Why are they saying that?

WELLS:  I think they're covering up the fact that they had a man in their custody for over half an hour and they didn't call the bomb squad, and I think they're covering up the fact that they know they have an innocent man, and they don't want to let it out that they were frightened into inaction on that day.

VAN SUSTEREN:  And when you say they had a man in custody, you're talking about the fact that your brother was there with that bomb collar around his neck and a half-an-hour period went by, right?

WELLS:  And he was handcuffed, and he had told the officers how he was shot at when he went to deliver pizza, how he was -- had the collar locked around his neck like a shack -- like a hand -- a huge handcuff, how he was told him and other people could -- could and would be killed if they tried to do anything other than following those instructions exactly.

VAN SUSTEREN:  All right.  Now the day -- on August 28 when your brother made this pizza delivery, do you know where he -- when he got the call at the pizza place, do you know where he delivered the pizza to?

WELLS:  To a TV tower.

VAN SUSTEREN:  Do people...

WELLS:  It's an abandoned TV tower.

VAN SUSTEREN:  I mean do people live there near this TV tower?  I mean -- I mean is it like a home, or what is it?  Just simply a tower?

WELLS:  There's -- there's a couple of houses on the deserted road that goes up on -- a dirt road that goes back to the towers behind a couple of houses.

VAN SUSTEREN:  And so he was just basically delivering a pizza to an address and...

WELLS:  Yes.

VAN SUSTEREN:  ... not to a home at the time.

WELLS:  Exactly.

VAN SUSTEREN:  Is it your suspicion that at that point this bomb collar and this bank robbery scheme was hatched?

WELLS:  That's where they put the bomb around my brother's neck.  After he tried to run through the woods and they shot at him -- you can see on the video he had dirt on -- dirt spots on his knees that I believe is when they knocked him down and clamped the bomb around his neck and gave him the notes and told him you're going to either die there in the woods right there or try to do this bank robbery for them...

VAN SUSTEREN:  John, is...

WELLS:  ... which I don't think was a bank robbery.

VAN SUSTEREN:  What do you think it was?

WELLS:  I think it was a message.  They were trying to kill -- they killed my brother in the middle of the afternoon surrounded by law enforcement.  They put a Guess T-shirt on him, taunting the law-enforcement officials in the middle of the afternoon.  This was a statement.  I don't know why.

VAN SUSTEREN:  John, is there a message to the FBI tonight directly from you?

WELLS:  I'd like them to solve this case, I'd like them to release all the notes, and I'd like them to stop slandering my brother and let the public know that he had nothing to do with this at all.

VAN SUSTEREN:  John, thank you.  I hope your brother's case gets solved quickly for you, sir.

WELLS:  OK.  Thank you.
