Information available so far indicates the devices used in the first three explosions were triggered as soon as they were picked up or moved, meaning they don’t require opening to detonate. The more sensitive triggering switch apparently used in these devices makes them more dangerous than the average parcel bomb. They are liable to explode at the slightest jostling or tilting. This means not only avoiding all contact with suspicious packages is essential, but not even approaching them is key.
And the March 18 device’s success, despite significantly different design, further suggests that the bombmaker behind these attacks is an accomplished one, and is likely to have received some training, perhaps as a military or police explosive ordnance disposal technician. Due to the bombmaker’s versatility, future bombings could use other methods to detonate devices, such as an infrared beam, pressure plate or remote control. Residents in Austin, as well as surrounding areas, should therefore be on the lookout for, and avoid, suspicious items and even roadside debris that could conceal explosive devices.
Sending a parcel through FedEx will leave many more pieces of evidence for investigators to develop. Still, there is a risk that further devices concealed in legitimate parcel packages are still in circulation. Anyone in the area who sees anything suspicious or out of place should keep their distance and alert authorities immediately.
