The citys mayor spoke to nbc about concern for the state of the country. Extremely concerned for the residents of the community, but more importantly extremely concerned for everybody in the state or country where somebody can drop a backpack in a garbage can with no timers and you have to wonder how many people could have been hurt. I dont have the expertise to determine the blast function of think people could have been severely hurt or injured if they were in the vicinity when that went off. Here with more on the investigation there. Reporter good morning. The mayor here of elizabeth, new jersey says multiple devices have been discovered here. When the bomb squad was cutting into the first device, we heard a loud explosion sending ce the area in different directions. The mayor says it was one of a backpack full of five devices that suddenly went off. Theyre now looking at the other four devices and trying to recover them and remove them from the area. The mayor says they were looking that devices and concerned about them when the bomb squad had been here for three or four hours and we heard all of a sudden that explosion. At first we were told it was a controlled explosion. Not. And he said had this bag of suspicious devices gone off, it was about 300 feet from the pub. It could have killed or maimed several people. The situation still unfolding. Still a very fluid situation. Back to you guys. And overnight, Law Enforcement officials tell nbc news they may have a possible suspect that scene. One of the bombs which Authorities Say was f shrapnel, went off during a busy saturday night injuring 29 people.
