Investigators have not found any evidence that an explosion in New York Saturday was tied to an earlier blast in New Jersey, New York City Mayor Bill de Blasio said Sunday.  In NYC, 29 people were injured, but thankfully none of the injuries were considered to be life threatening, and they  have all been released from the hospital.

"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," de Blasio said.

 "We know there was a bombing. That much we do know. We know it was a very serious incident," he said.
 "But we have a lot more work to do to be able to say what kind of a motivation was behind this. Was it a political motivation? Was it a personal motivation? We do not know that yet."
