From first KTUL article. Cindy Morrison reports "...rumors that Hinrichs tried numerous times to get into the stadium that night.
The FBI (website )is now heading up the case and had no comment today. But, sources in law enforcement confirm Hinrichs used a very unstable explosive that may well have gone off early by accident.
Some published reports claim Hinrichs' bomb was the same homemade explosive used recently in London. Acetone peroxide is extremely volatile. Experts tell us it can detonate if dropped even an inch.
We called Scotland Yard today and were told if Saturday's bomb was the same material as the London bombings, the FBI would have contacted them. But, the investigator overseas wouldn't confirm if that had happened.
The investigation into the explosion continues. And, investigators are trying to find out what Hinrichs had in mind that night. Our sources do confirm evidence in Hinrichs' apartment shows he made the explosive and even tested it prior to Saturday night."
. Acetone peroxide is extremely volatile.
That is what they used? Nasty stuff.
