So do we have a number of tanks that are about equal to the number of phones stolen? So these are tanks that are from these outdoor exchange stations where you can insert an “empty” tank and remove a full one? There is a lot of space at the bottom of a propane tank. That could easily hide some explosives and a cell phone and tucked into a spot in the midst of full tanks....at a gas station....or where grandma gets her prescriptions filled?
Looks to be about twice as many phones as propane tanks. Which figures out about right if you figure two phones per tank - one for the detonator on the tank and one to set it off.
