Three pipe bombs found in New Jersey and two IEDs that terrorized New York City on Saturday all have one thing in common – cell phones.
An old-school flip phone was used as a timer in all five home-made bombs. Authorities said they still have not found any indication the incidents in New Jersey and New York are related, but in both cases flip phones were used as timers to detonate the explosives.
All phones used as detonators were similar in design, according to PIX 11. This comes as CNN claimed to have seen video which places the same man at 23rd and 27th streets in Manhattan – where one bomb detonated and another pressure cooker device failed to detonate.
The security footage from Saturday reveals a man dragging what appears to be a duffel bag on wheels near to the bomb detonated on 23rd street. This was 40 minutes before the blast Another video also appears to show the same duffel bag on 27th street.
In this video, the man seen at both locations leaves it and then two men approach the bag and remove a white garbage bag. It is not know if the two men are connected with the individual seen at both locations.
‘We don’t have everything in. Think of a jigsaw puzzle out in the street right now,’ said NYPD Chief of Detectives Robert Boyce. ‘Do we think they’re related? Yes, we have to move in that direction, but right now we’re not ready to make those calls yet.’
The explosions happened on the same day a pipe bomb went off near a Marine Corps charity run in New Jersey and nine people were stabbed by a man at Minnesota mall – leading some to say America underwent three terror attacks in the space of 12 hours.
‘We do not have any specific evidence of a connection, but that will continue to be considered. We’re not taking any options off the table,’ New York City Mayor Bill de Blasio said.
Investigators told NBC 4 New York all the old-fashioned flip phones were found attached to the devices. Authorities have also said another similarity was the lack of know-how that went in to making the bombs. Out of the five devices found or detonated on Saturday, three failed to work as designed.
An undetonated pressure-cooker explosive had a cell phone attached to it and New York Governor Andrew Cuomo said the device was similar to the one that exploded in the Manhattan neighborhood of Chelsea. Additionally, the devices found in New Jersey contained an easily obtainable explosive black powder.
Residue of an explosive often used for target practice that can be picked up in many sporting goods stores was also found in the Manhattan bombing, a federal law enforcement official said Sunday.
The residue comes from Tannerite and may be important as authorities probe whether the blast was connected to the unexploded pressure-cooker device found by state troopers just blocks away, as well as the pipe bomb blast in New Jersey.
No Tannerite residue was identified in the New Jersey bomb remnants, in which a black powder was detected, said an official who spoke to The Associated Press on condition of anonymity.
Tannerite, which is often used in target practice to mark a shot with a cloud of smoke and small explosion, is legal to purchase and can be found in many sporting goods stores.
Experts said a large amount would be required to create a blast like the one Saturday night, as well as an accelerant or other ignitor.
