EXCLUSIVE: Cell phones intentionally jammed at Virginia Tech by authorities

“There was a great deal of concern over the possibility that explosive devices were planted at Virginia Tech.”

19 April 2007: While there appears to be growing criticism over law enforcement’s handling of the events that unfolded Monday at Virginia Tech, they should be commended for covering a number of other potential scenarios that nightmares are made of in this post 9/11 society.

According to a law enforcement source speaking to this investigator this morning, authorities were very concerned that improvised explosive devices were planted at the Virginia Tech campus prior to the shooting by the killer that they used a tool that is frequently employed in Iraq - a device that jams radio signals, including those used by cellular telephones. The tool, known as Warlock Blue, jams radio frequencies intended to detonate hidden, remotely detonated “improvised explosive devices” or IEDs that are often triggered by cell phones, garage-door openers and similar radio controlled devices. The countermeasure could have also prevented any communications between perpetrators if others were involved, added this source.

Our law enforcement source confirmed that Cho Seung-Hui, who also sent a lengthy, profanity laced “manifesto” ranting against US and Western values - one that references al Qaeda and the attacks against the US - has been “connected” to at least one of the bomb threats called in to the University on the day of the carnage. Authorities are also investigating his possible role in the previous 2 bomb threats made earlier in April, suggesting that perhaps he was observing authorities’ response to such threats.

As we reported on Monday, “Following the initial shooting at ‘West A.J.’ early this morning, police believed the suspect left the campus… It was during that investigation that the suspect returned to the campus prepared to kill as many people as possible. This was a premeditated act of mass murder, planned well in advance.”
