Tannerite investigator says it's improbable the compound was used in bombings

NEW YORK – Law enforcement officials say they found remnants of the explosive compound Tannerite at the scene of the bombings in New York over the weekend.

But an investigator for the Pleasant Hill, Oregon-based Tannerite company says that might not be the case.

Tannerite is a copyrighted formula for rifle practice and an investigator for the company says it only explodes from the impact of a center fire rifle.

He said that makes it an improbable, or at least impractical, substance for the New York bombing.

In past investigations, he’s found there are usually two possibilities.

“It either: A, wasn't Tannerite; or B, if it was, somebody was using it as it was unintended and they added something to it or they changed its property somehow, but they were still shooting it," said Steve Yerger, a Tannerite corporate investigator.

Yerger said it may be that investigators are using the word “Tannerite” for an explosive substance like some people say “Kleenex” for a tissue.

He said it could have easily been something else resembling Tannerite. He’s working with the FBI to get to the bottom of this.
