EDISON - Authorities say there are over 1,000 people from 30 federal, state and local law enforcement agencies working to find the person or people responsible for the deaths of three people at the Boston Marathon Monday.
Granville Long, a former senior FBI agent, helped lead the investigation into the Oklahoma City bombing. He says cell phones and surveillance cameras have contributed enormously to the amount of information available to investigators. The challenge is sorting through that information to find real clues into the crime.
Long says the FBI looks for patterns in the vast amounts of data that may not be obvious at first. Cell phone records of calls made in the area of the bombings have already been subpoenaed. It may take a few days, but Long says eventually there will be helpful information.
