The suspect (or suspects) is not ringing the doorbell with the delivery, Manley said, so it is unclear how long the packages were on the victims' porches before they saw and moved them.

\"What we know is when the victims have seen these packages on the front porch, they have gone out and handled them in some way or another and have had the explosions occur,\" Manley said.

There was \"significant damage\" to the porch involved in the March 2 blast as well as at least one of the blasts this morning, Manley said.

\"These devices can explode in many ways, either by being moved or being opened so that’s why I want to reiterate the importance that if you see something that’s out of place, do not handle it, do not move it, do not touch it. Call us,\" Manley said.
