(CNN) -- The FBI on Tuesday released photos of a steel collar used to secure a bomb to the neck of a pizza deliveryman killed last week after robbing a bank in Erie, Pennsylvania.

Investigators also said they had found no direct connection between the death of the deliveryman -- Brian Douglas Wells -- and later death of a friend and co-worker.

FBI Special Agent Bob Rudge said the bomb's locking device was unique, sophisticated and has "significant lead value" to investigators.

The FBI said it had released the pictures in hopes that someone will remember seeing it somewhere before the robbery.

"We feel this device was made uniquely for the incident at hand," he said. "We are hopeful that by showing a picture of the device, someone may recognize the instrument, the metal, the locking material used to secure it to the neck and, certainly, call us with that information so that we can further examine the details of its construction."

Wells, 46, was killed Thursday afternoon when a bomb attached to the collar exploded after a bank robbery. Wells had told police he had been forced to rob the bank.

Sinister looking device.

What?

[Lazamataz]

Jeez louise. I'm beginning to believe this (dead) guy. Looks like he was genuinely forced to rob this bank.

What a grim situation. Wonder how many copycats?

[JOE6PAK]

Did the bomb blow his head off?

[danneskjold]

what happened to the money?

[Uncle Miltie]

You don't make just one of those.....

Wasn't there some movie with this same concept? A prison where every prisoner wears an explosive collar, along with another. No one knows who his partner is, and they can't be any more than 300 feet away from each other or else both collars explode.

Somehow I totally missed the original threads on this. Anybody got any links?

Don't forget these collars:

Collar empty and no sign of Clinton.......Terry, in a panic, starts with calls the local gentlemen's clubs...developing.

It's an industrial compressed gas bottle holder, intended for securing gas bottles.

So that is "THE" collar?

It doesn't look like it's been thru an explosion.

Looks like it was designed to only take out the person wearing it.

OMG. How creepy.

[GretchenEE]

This is a frightening, freaky story ... I saw the video on the news last night of the handcuffed delivery man asking for help ... I am really, really wanting the whole truth to be found out in this situation. It is easy to imagine copycats hard at work for God-knows-what reasons or agendas.

Some pizza parlors in Pennsylvania are notorious for their connection to the mob and the drug trade. I would look for a drug connection first.

The device is way too elaborate for this poor man, Wells, to have designed and executed. And way too complicated for a suicide.

Or, it could be the work of another "Mad Bomber" like George Metesky, the infamous NYC bomber who made and set off his devices as revenge for his firing by Con Ed in the fifties.

Someone who ordered pepperoni and got mushrooms instead?

[theDentist]

Yes. Thanks everyone. I found I have it on video. I got about 25 mins into it and realized it wasn't worth watching again.
