Investigators say there is a possible match between the NY and NJ bombs as far as design is concerned and they used similar triggering devices, They are quick to point out that no positive has been proven yet as the investigation is still continuing. Gov Andrew Cuomo revealed that the two devices in New York were similar to each other and both used a cell phone as a timer. The second device, which was found about four blocks away from the one that exploded did not detonate. The FBI is taking it back to Virginia for comprehensive examination.
Earlier, New York Governor Andrew Cuomo said the two devices in New York — a bomb that exploded Saturday night in the Chelsea neighborhood and an unexploded pressure-cooker device found nearby — were similar to one another. Officials told CNN the two devices in New York City both used a cell phone as a timing device. The phones were also similar in design, officials said.
Three devices along a charity-race route in New Jersey — only one of which exploded — were also rigged to detonate using a cell phone as a timer.
The devices in New Jersey contained black powder, which is an easily attainable explosive ingredient, several law enforcement officials told CNN. The FBI is planning to take the New York pressure-cooker device to its lab in Quantico for further analysis.
None of the devices are very sophisticated, but they show enough know-how to be lethal, officials said.
