At least three dead and four injured during a shooting at a festival in Seattle. Thousands had gathered for the annual Bite of Seattle food and music festival near the space When it started shooting, when everyone started running, everyone got scared. I mean pushing each other, running over signs. Police say two men were involved in a gunfight. Officers responded and addressed one of the shooters. That person gave up and was taken into custody. There was another person that we believe that was also involved that fled the scene. Two victims declared dead at the scene. A third died in the hospital. Officials say four other victims all suffered gunshot wounds ranging from a two-year-old boy to 39 years old. It's one thing to note, one of the four victims that was taken to the hospital was a toddler. Again, this is a terrible, terrible event. Federal authorities joined the investigation. Bill Daley, formerly with the FBI, calls it a challenging crime scene with no fixed cameras in the 74-acre park.

So that's where perhaps technology, cell phone data will come into play to be able to identify where this person is. Police are asking witnesses to come forward with what they saw in any video that could help the investigation.
